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 11 publicity sessions. A total of 1,524 tons of Liquor digestate was provided to farmers for trial use, and 37 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 are too low SV 30 (100%),too much sludge in the anaerobic tank or sedimentation tank (90%),and insufficient retention time for anaerobic fermentation (57%).
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 83 livestock farms have been assisted plan for Implementing Liquor and Fiber Digestate as Fertilizer for Farmlands. Assisted 30 livestock farms to reuse effluent water. Assisted in submitting 8 livestock farms to submit change applications and 37 livestock farms to submit extend applications. Submitting monitoring reports of the ground water and soil of 114 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 453,600 CMD and 444,960 CMD on holidays; The daily monitoring flow of Xingshe Bridge is 1,232,640 CMD on weekdays and 1,182,240 CMD on holidays. The daily monitoring flow of Gangsi pumping station is 1,843,200 CMD on weekdays and 2,404,800 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 197 inspections of livestock and collected 11 water quality samples. The total number of violations reported on livestock farms was 13 times, and the fines amounted to approximately NT$280 thousand.
According to the ''2022 Water Pollution Prevention and Control Assessment Plan'' announced by the EPA, assisted in the development of the ''2022 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 2022 water pollution prevention and control evaluation project results report.
