The survey is conducted on the livestock industry in Yunlin County, including the distribution location of the livestock industry, the percentage of pollution contribution, and the relative location of key impact stations. Animal husbandry, mainly investigated in Beigang River Basin, Xinhuwei River Basin, Zhuoshui River Basin, Dayilun Pai, Bajiaoting Pai, Shicuoliao Pai, Youcailiao Pai, Magongcuo Pai and Niutiaowan Pai The location distribution of animal husbandry in other areas, and the relative locations of key water quality measuring stations including Tuku Bridge, Fengqiao, and Haifeng Bridge.
According to the distribution of animal husbandry and the pollution load in Yunlin County, a list of suggested livestock farms (215) that proposed guidance on the use of biogas slurry and residues for agricultural land fertilizers was carried out to investigate the compliance of on-site equipment and regulations of livestock farms, so as to understand the waste of livestock farms ( The current status of wastewater treatment facilities, the number of days of anaerobic fermentation, the use of biogas collection, the conditions of agricultural land that can be irrigated with biogas slurry and residue, and publicize with livestock farmers the application conditions, methods and related water pollution for using biogas slurry and residue on agricultural land Act, and has completed 10 publicity briefings; and has completed the purchase of 1,000 publicity materials. The production of the promotional program on animal husbandry and urine resources for TV media was completed on November 8, and it was broadcast on Jialian and Beigang Cable TV Company for one month (November 16-December 15).
Integrating the transportation and irrigation operations of livestock manure resources utilization has successfully coordinated 10 farms to assist in carrying operations, and assisted in carrying other livestock farms that have not yet installed vehicles for the utilization of livestock manure resources for irrigation operations. In addition, a total of 611 livestock farms have been obtained for the recycling of biogas slurry and residues. The livestock farms have a total of 242 vehicles for transporting biogas slurry and residues and 59 individual reuse vehicles, a total of 301 vehicles. Also matchmaking to establish at least 5 teams of animal husbandry excrement and urine resource utilization transportation and irrigation teams, each team has at least 2 irrigation vehicles, and the team composition targets include livestock farms that are subsidized to purchase biogas slurry and residue transportation vehicles or set up and purchase vehicles by themselves .
Applying for the use of biogas slurry and residue for agricultural land fertilizer has guided 70 livestock farms to apply for operations, and has sampled 70 points of biogas slurry and residue, 140 points of groundwater quality background value detection, and 210 points of soil quality background value detection. In addition, tracking soil and groundwater monitoring operations after biogas slurry or biogas residue irrigation, has completed 106 livestock farm sampling, 231 points of groundwater quality monitoring operations and 326 points of soil analysis and monitoring operations. At the same time, it assisted 16 livestock farms to handle changes and 46 farms to handle extension operations.
A total of 611 animal husbandry manure resources were used, the approved irrigation amount was 2,253,433.9 metric tons per year, the area of irrigated farmland was 1,466.09431 hectares, the pollution was reduced and the biochemical oxygen demand (BOD) was 14,559 metric tons, and the suspended solids (SS) was 18,807 metric tons. About 121,000 packs of Taifei No. 5 fertilizer can be saved every year.
Completed the establishment of the LINE official account for the recycling of livestock manure and urine resources, and 406 livestock farmers and farmers have joined. In addition, the Yunlin County Biogas Slurry and Residue Farmland Fertilizer Use Promotional Website has been updated, maintained and built, and the administrative report has been filled in every month The Environmental Protection Department of the Institute of Animal Husbandry Manure Resource Utilization Management Examination Tracking Management System.
