This project assists two evaluation meetings arose in the company of relevant authorities to review the progress of key monitoring stations as follows: (1) utilization of animal manure resource (2) reduction of the pollution (3) current status of the wastewater management plan and (4) its assessment scores. In addition, as the strengthening inspection is implemented toward animal husbandry, the outcome including the amount of fine and the number of inspections, samples as well as infractions will be scrutinized thoroughly via monthly rolling adjustments. In order to improve the efficient disposal of the livestock manure though either the cooperation amid farms or centralized waste treatment, thirteen steering sessions took place in following places, inclusive of one in Taoyuan City, one in Kaohsiung City, one in Chiayi County, one in Tainan City, one in Changhua County, five in Yunlin County, two in Pingtung County, and one in Hualien County. Each session invited two committee members to conduct site surveys and give feedback to assist the re-examination work of which the cycle accounted for up to thirteen times. According to the analysis of the single purchase rate of the 11 cases containing anaerobic fermentation equipment in the completed power generation, and it is recommended that the purchase rate of biomass energy with anaerobic digestion equipment should be increased year by year to encourage the industry to develop biogas power generation. On the other hand, the project has handled eight agricultural and animal husbandry briefings; it has conducted an agricultural and animal husbandry survey to understand targets’ willingness and to lessen their concerns for the amount of irrigation and its efficiency. Besides, several meetings involving enterprises and livestock farms also were held, three seminars and ten consultation meetings included. The purpose of the meetings is (1) Taiwan Sugar Corporation(TSC) Land Irrigation Planning Research and Consultation Meeting, inviting TSC and relevant agricultural and forestry units to participate in the discussion of the feasibility of biogas slurry and biogas residue irrigation and afforestation land, (2) Yunlin vermicompost site and test site ammonia nitrogen emission reduction technology discussion and business meeting, and (3) Discussion on the feasibility of animal husbandry discharge and drainage of agricultural irrigation and drainage and the procedures for stopping irrigation of biogas slurry and biogas residue. By doing so, for one thing, relevant policies, known as appropriate recycle of livestock manure, can reach more publicity; for another, more resources can be used efficiently and less discharge of livestock waste into rivers. Case studies referring to biogas slurry and residue as fertilizer have been completed, and two analytical evaluations related to actual irrigation and quality of underground water as well as soil have been examined all together. Plus, six townships sites to promote irrigation matters to increase farmers' willingness to water. This project is to collect and organize the statistics from nine assigned rivers; the data consist of the basin environment, water quality, distribution of pollution, the emission list, and analyses between animal husbandry resources and water quality. Through continuous examination and discussion, current utilization and possible suggestions are represented. Evaluate the operational effectiveness of the small modular anaerobic fermentation tank in Yunlin Livestock Farm, which has been subsidized by the Department for 110 years set up a single-stage anaerobic treatment facility test site to conduct performance, including at least wastewater treatment efficiency, pollution reduction benefits, biogas production, copper and zinc changes in sediment, effluent water and sediment totality Phosphoric anhydride and total potassium oxide content data, and provide suggestions for the optimal operation mode respectively, and prepare operation and maintenance manuals to facilitate future application and promotion of livestock farms. For small and medium-sized pig farms, improve their livestock wastewater treatment procedures, adjust short-cut nitrification-anaerobic ammonium oxidation technical parameters, limit the mechanistic relationship between nitrite and nitrate in livestock wastewater, and directly allow nitrite to react with the original material. The ammonia nitrogen in the wastewater reacts into nitrogen and escapes into the atmosphere, greatly reducing emissions of greenhouse gases such as CO2 and N2O; extracting specific proteins and cellulose digestive enzymes in agricultural waste as feed additives to activate the digestive system of pigs and change pig feces and urine microorganisms Bacterial phase, moderately adjust the parameters of the livestock wastewater aeration unit to achieve the occurrence of anaerobic ammonium oxidation in the wastewater, reduce the ammonia nitrogen concentration of the livestock wastewater, and simultaneously reduce the conductivity and COD concentration. As the addition time increases, the livestock wastewater has a downward trend.
