This extended plan mainly carries out the effectiveness tracking of approved irrigation, promotes the utilization of animal husbandry and urine resources, and sets up a fleet of irrigation and transportation vehicles. Regarding the effectiveness tracking of livestock farms that have been approved for application of biogas fermentation residue, there are 72 times of groundwater monitoring for high and low water level periods (including 12 times of retest, excluding EPA monitoring station and shared groundwater monitoring well) and 87 times of soil monitoring operations which have been completed. The monitoring results have not exceeded the soil pollution monitoring standards. Regarding the groundwater monitoring, there are 8 times (5 times for the upstream and 3 times for the downstream) after the retesting in the low water level period. The overtake number after the retest in the high water level period is 6 times (4 for the upstream and 2 for the downstream). It is because the monitoring well is located in the upstream of the irrigation area, and it should not be caused by the application of the biogas fermentation residue in this case. In addition, the livestock farms that exceeded the standard in the downstream, after examining the records of irrigation, in the case of an unapplied behavior, the other application amount only accounts for 22.8% of the approved irrigation amount. Therefore, it is suspected that the downstream ammonia nitrogen exceeding standard should not be caused by the application of biogas fermentation residue, and the monitoring data should be obvious. The upward trend is the benchmark, and groundwater will continue to be monitored in order to clarify whether there is a significant increase in the ammonia nitrogen measurement. At this stage, it is recommended that the farmers can continue irrigation. Moreover, the irrigation condition was tracked every three months, and there are 29 field experts submit the evaluation report.
As for the promotion of animal husbandry utilization, the amount of water, waste (sewage) water discharge and reprocessing margin have been designed according to waste (sewage) water treatment facilities. We selected 22 animal husbandry operators for promotion, and investigated the raising scale, waste (sewage) water discharge, and available agricultural land area within 5km of the livestock farms operators, as well as developed feasibility strategies for animal husbandry and urine resources. As of November 30, 22 counseling and field surveys have been completed. There are 19 sessions with willingness, 11 of which are willing to accept the pig manure and urine, including the 5 which has been applied on June 20, August 29, September 21 and October 18. There are 1 sessions of composing, 2 sessions of livestock farm matching, 2 sessions of negotiation, 1 session of acceptance. There are 8 sessions that are not willing to accept the admission of other fields. The main reason is that they only want to do self-power generation, and the epidemic prevention problem has been applied for by the Council of Agriculture, Executive Yuan.
Regarding 5 animal husbandry applications, it is estimated that the annual resource utilization will be 292,605.9 metric tons, the daily reduction of BOD is 5,371.1 kg, SS is 6,333.1 kg, and NH3-N is 308.6 kg. The pollution reduction amount reached the target set by the Environmental Protection Administration, Executive Yuan. It is expected to improve the pollution load of key monitoring stations, reduce the water pollution control cost of about 1,579,270 NTD, and got 11,582,910 NTD revenue from sales of electricity sales.
In addition, there have been 7 publicity meetings or seminars completed, with 116 participants, a press conference on the results of livestock and feces and urinary resources held on October 30, and 1 animal husbandry and feces recycling treatment plan observation and learning activity from November 1 to 3, 2018. It brought visitors to understand the recycling of biogas power generation, biogas fermentation residue, agricultural waste developed into renewable energy (fuel rods) and solid waste recycling. The actual number of participants was 71, but some participants were unable to participate in the whole process due to personal factors. According to statistics, the number of people participating in the observation and learning activity was 40, 500 leaflets were prepared, and 13 roll up banners were made to demonstrate the outcomes of the use of the biogas fermentation residue as fertilizer for animal husbandry.
As for the establishment of biogas fermentation residue fertilizer transportation and irrigation system, according to the statistics, there are 12 animal husbandry applicants who are willing to apply for the application of the vehicle or the farmland storage bucket, whereas 58 applicants with unwillingness. The main reason for the investigation is that the purchase funds for the existing tank trucks, mainly for pipeline irrigation are too high. The subsidy for the purchase of tank trucks exceeds 3.5 tons, required a large truck driver's license. In addition, we also carried out the construction of the liquid and sewage residue and the use of the transportation and irrigation system according to the investigation of the application of the vehicle. The implementation of this expansion plan assisted 12 animal husbandry companies who are willing to apply for biogas fermentation residue irrigation operation plan on July 10 and 11. The project team assisted the second batch of animal husbandry who wished to apply for a biogas fermentation residue operation plan on November 27 and 28. A total of 9 farmland storage buckets and 7 irrigation vehicles were purchased in advance. We continue to assist animal husbandry to carry out the painting of “farmland biogas fermentation residue irrigation” in the vehicles or tanks.
