Tainan City-112 Tainan City Livestock Wastewater Ammonia Nitrogen Recovery Promotion Plan

英文摘要 The start date of this plan is April 28, 2020, and the plan implementation period is November 30, 2020. This year, 30 companies have been matched with priority to promote the use of biogas residue and biogas slurry as agricultural land fertilizer, and completed Submit 30 applications for biogas slurry and biogas residue as agricultural land fertilizer points to the Agriculture Bureau for review, of which 28 are pig farms and 2 are cattle farms. Seven of them are located upstream of key measuring stations in the watershed under their jurisdiction (accounting for 33% of the total), with a total irrigation area of 17.05 hectares and an irrigation volume of 29,545 metric tons. In 112 years, we have passed the guidance of Longfeng Livestock Farm, Dachengcheng-Nanxi Livestock Farm, Qingyao Livestock Farm, Shanghao Livestock Farm, Wangjiang Breeding Livestock Farm, Jinhong Livestock Farm, Yongnian Livestock Farm, Chunquan Livestock Farm, Tongqun Livestock Farm, 17 livestock farms, including Zhenxing Livestock Farm and Lin Jinjie Livestock Farm, applied for the release of runoff water for recycling. A briefing session will be held after August, and a total of two regulatory briefing sessions will be held in August. During the meeting, a preliminary willingness survey and satisfaction survey form will be distributed to livestock farmers, allowing the livestock industry and farmers to check whether they are willing to carry out livestock manure, urine and slurry digestion. After the meeting, the staff will conduct a survey and statistics on the willingness of the farmers to use fertilizers. For those who are interested in animal husbandry and farmers, dedicated personnel will further contact them to conduct on-site surveys and assess the on-site conditions. If they meet the conditions, dedicated personnel will match the livestock households and farmers. An application was made for the use of livestock manure, slurry and biogas residue as fertilizer for agricultural land. A total of 205 people attended the three regulatory briefings. The monitoring of groundwater demonstration households in 2012 is 111 livestock farms, and the monitoring of soil demonstration households is 111 livestock farms. The groundwater quality background value detection operation in the irrigated agricultural land area should include items such as conductivity, ammonium nitrogen (NH4+-N) or ammonia nitrogen, etc. And groundwater well data (coordinates/land number/well depth), and the soil quality background value detection operation of irrigated agricultural land should include soil saturated extraction liquid conductivity, copper, zinc and other items, as well as soil texture, and sampling location information (Coordinates/Place No.), as of November 18, 111 demonstration households (204 points) have completed soil quality monitoring operations, and 204 soils have been collected, of which 204 monitoring reports have been obtained. The monitoring results of the issued monitoring report show that the heavy metal copper (Cu) in the soil meets or falls below the 85% limit of the "Soil Pollution Monitoring Standard (Food Crop Farmland)": 102 mg/kg, with an average value of 11.4 mg/kg, a maximum value of 40.2 mg/kg, and a minimum value of 0.97 mg/kg; soil heavy metal zinc (Zn) all meets or is lower than the "Soil Pollution Monitoring Standards (Food Crop Farmers)" (Ground) 85% limit": 221 mg/kg, the average value is 77.36 mg/kg, the maximum value is 209 mg/kg, and the minimum value is 37.2 mg/kg. The soil conductivity monitoring results show that the average value is 309.27 μS/cm, the maximum value is 2,330 μS/cm, and the minimum value is 30 μS/cm, which are all in line with the expert recommended benchmark value of 4000 μS/cm for stopping irrigation (based on the test results of saturated extracted liquid ). Demonstration households monitor the groundwater quality background value of 111 fertilizer use plans, with a total of 164 monitoring wells. As of November 17, 2020, 164 monitoring wells have been surveyed. The average ammonia nitrogen concentration in Tainan's groundwater is 1.93mg/L. The maximum value is 26.8 mg/L, and the minimum value is 0.01 mg/L. Among them, 16 groundwater wells have exceeded the irrigation stop benchmark set in the application. Further follow-up analysis has shown that the average groundwater ammonia nitrogen concentration in recent years is 2.03 mg/L, which is higher than the second Similar to the groundwater monitoring standard (0.25mg/L), especially in Yunlin, Chiayi, Tainan and other places that are also part of the Jianan groundwater division, the concentration of ammonia nitrogen in groundwater is significantly higher. The ammonia nitrogen pollution potential of Tainan City and Kaohsiung City is much higher than that of other places. In areas with high levels, wellheads that exceed monitoring standards are listed as warning wells, and operators are informed to reduce irrigation. If the level continues to rise, the agricultural authorities will be notified and issued a document notifying operators to temporarily stop irrigation to clarify the reasons. This year, 32 demonstration households (with at least one expert and scholar present) were selected. In August, experts and scholars were invited to conduct on-site survey and counseling for livestock farmers who had applied for irrigation approval. As of November 30, 32 demonstration household counseling sessions had been completed based on various The current status of site irrigation and the current status of equipment lists suggestions and improvements. It is hoped that through coaching, the demonstration households' understanding and practice of irrigation operations will be strengthened. The drainage water quality of this area (7 points including the upstream and downstream of the key measuring station "Province 19 Jiji Shui Stream Bridge", the upstream and downstream of Baweng Drainage, the South Baweng Drainage, and the upstream and downstream of Wencuo Stream (Kui Chai Harbor Drainage)) is conducted every month. Sampling work (RPI water quality project), sampling of the upstream and downstream rivers in the dairy farming area has been carried out every month since the start of the plan. Water quality sampling operations from May to November have been completed. The sampling results of the rivers from May to November show that most of them are seriously polluted. The actual amount of irrigation applied from January to November this year totaled 307,934.39 metric tons, while the approved applied irrigation amount for the whole year was 373,876.7 metric tons/year. However, because most crops such as feed corn, rice, wendan and sweet potatoes are fertilized during the fertilization period. Between summer and autumn, most crops are in the fallow or harvest period in the first half of the year, so the frequency and amount of irrigation are not yet high. However, since the rainy season begins at the end of June, with heavy rainfall and a long rainy season, basal fertilizer application begins in August. The amount of irrigation is on the rise, so the amount of biogas slurry and biogas residue applied for irrigation will increase in the second half of the year. In the future, we will continue to regularly track the usage of operators and farmers, and be required to accurately fill in the irrigation record form. Analyzing the city's 220 approved uses of biogas slurry and biogas residue from 105 to 2012, of which 137 are pig farms and 83 are cattle farms. Analyzing the watershed and administrative district distribution of the 220 applied farms, Tainan City currently approves irrigation The total area is 303.19 hectares, the irrigation volume is 407,551 metric tons per year, and the number of irrigation heads is about 25,910 pigs and 6,887 cattle. It is estimated that it can reduce biological oxygen demand (BOD), suspended solids (SS) and other pollutants, ammonia nitrogen (NH3-N) and other pollutants, BOD is reduced by approximately 883 metric tons/year, SS is reduced by approximately 1,751 metric tons/year, and NH3-N is reduced by approximately 186 metric tons/year, which helps to improve river pollution levels; crops used to irrigate farmland are mainly Pennisetum, green cut corn and feed corn are the main species. The Tainan City Environmental Protection Bureau purchased two 3.5-ton tank trucks starting in 2019. From May 1 to November 30, they carried a total of 944 trips, applied 3,304 metric tons of irrigation, and carried a distance of 3,097 kilometers. The main irrigation applications were Feed corn is the main food, followed by rice, and then sugar cane. It is estimated that the carried irrigation will reduce the pollution of the original water body by 10,447 kilograms, ammonia nitrogen reduction of 779 kilograms, and BOD reduction of 8,185 kilograms, among which the reduction effect of Jishui Creek is the most significant. The detailed cost calculation is shown in Table 3.9.4-2. The charging rates are recommended to be classified according to the kilometers of transportation. There are five levels of classification: at least 187 yuan per ton within 5 kilometers of the round-trip distance, at least 271 yuan per ton within 10 kilometers, and at least 271 yuan per ton within 15 kilometers. The fee per ton within 20 kilometers is at least 322 yuan, the fee per ton within 20 kilometers is at least 390 yuan, the fee per ton within 30 kilometers is at least 495 yuan, and the fee per ton within 50 kilometers is at least 974 yuan.
