Overview of livestock in Taiwan, Pingtung County is second place, and livestock wastewater has high concentration of organic matter, suspended solids, salinity and high pollution load characteristics. If it is not properly treated, it will threat to the natural environment and domestic water. In order to reduce livestock pollution, and effectively improve the Pingtung's water quality and environment, we will keep promote policy about reuse Liquor and fiber digestate in Pingtung. In order to promote policy about reuse Liquor and fiber digestate as Farmland Fertilizers, this project handled 15 publicity sessions, with 1,635 attendees. A total of 1,512 tons of Liquor digestate was provided to farmers for trial use, and 35 agricultural lands were successfully matched to join the ranks of biogas slurry irrigation. This project establish livestock counseling team, and provide 50 livestock farms customized counseling and improvement suggestions. The main shortcomings are too much sludge in the anaerobic tank or sedimentation tank (78%), insufficient retention time for anaerobic fermentation (72%), and too low SV 30 (64%). For livestock farms that want to use Liquor and fiber digestate , we have arranged to perform the application condition check and on-site survey, and 87 livestock farms have been assisted plan for Implementing Liquor and Fiber Digestate as Fertilizer for Farmlands. Assisted 27 livestock farms to reuse effluent water. Assisted in submitting 14 livestock farms to submit change applications and submitting monitoring reports of the ground water and soil of 92 sites to the local competent authority for reference. The monitoring data all meet the monitoring standards. Due to the lack of data on the flow of rivers. This project implements water measurement at key stations. The daily monitoring flow of Jiuru Bridge is 414,720 CMD and 374,400 CMD on holidays; The daily monitoring flow of Changnong Bridge is <75,456 CMD on weekdays and <71,424 CMD on holidays. The daily monitoring flow of Xingshe Bridge is 407,520 CMD on weekdays and 419,040 CMD on holidays. The water quality of Shashe Creek is at a moderate to severe pollution level. The characteristics of high ammonia nitrogen and high biochemical oxygen demand indicate that the pollution sources in this basin are mainly people’s livelihood and livestock wastewater. In order to effectively integrate Pingtung's inspection and guidance resources, and to divide the scope of inspection with the Environmental Protection Agency and the inspection plan team, and only poor quality of the discharged water are collected and sent for inspection during the inspection. This plan has completed 849 inspections of livestock and collected 48 water quality samples. The non-compliance rate reached 100%, of which 81% were severely exceeding the standard. The total number of violations reported on livestock farms was 143 times, and the fines amounted to approximately NT$7.24 million. According to the ''2021 Water Pollution Prevention and Control Assessment Plan'' announced by the EPA, assisted in the development of the ''2021 Water Pollution Prevention and Control Assessment Plan Key Station Pollution Reduction Plan''. For achieve good evaluation results, we had followed up each project every month, hold regular meetings to conduct rolling reviews, formulate implementation plans for various plans to execute, and assist submit Q1~Q3 results about Pintung river quality and the 2021 water pollution prevention and control evaluation project results report.
