Livestock Wastewater Ammonia Nitrogen Recovery Promotion and Reducing Total Maximum Daily Load Strategy in Pingtung County,2023

Absrtact
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. A total of 7,308 tons of Liquor digestate was provided to farmers for trial use, and 41 agricultural lands were successfully matched to join the ranks of biogas slurry irrigation. This project establish livestock counseling team, and provide 30 livestock farms customized counseling and improvement suggestions. The main shortcomings too much sludge in the anaerobic tank or sedimentation tank (90%),too much sedimentation scum (80%) and are too low SV 30 (67%). 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 79 livestock farms have been assisted plan for Implementing Liquor and Fiber Digestate as Fertilizer for Farmlands. Assisted 47 livestock farms to reuse effluent water. Assisted in submitting 8 livestock farms to submit change applications and 33 livestock farms to submit extend applications. Submitting monitoring reports of the ground water and soil of 163 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 427,680 CMD and 457,920 CMD on holidays; The daily monitoring flow of Xingshe Bridge is 2,304,000 CMD on weekdays and 2,332,800 CMD on holidays. The daily monitoring flow of Gangsi pumping station is 5,313,600 CMD on weekdays and 5,472,000 CMD on holidays. Cooperate with the PTEPB to carry out special inspections on livestock farms, and only poor quality of the discharged water are collected and sent for inspection during the inspection. This plan has completed 90 inspections of livestock and collected 2 water quality samples. According to the ''2023 Water Pollution Prevention and Control Assessment Plan'' announced by the Ministry of Environment ,assisted in the development of the ''2023 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 first half results about Pintung river quality and the 2023 water pollution prevention and control evaluation project results report.
