According to the changes in regulations and how to deal with them in the factories, this project held 2 regulation briefing sessions and invited experts and scholars to give lectures on relevant content, with a total of 169 people participating. In addition, 270 companies under the jurisdiction of Tainan City under the strict control of ammonia nitrogen were inspected. Sampling work, audit rate 100.0%. In addition, this plan also implements the key inspection work in the Sanyexi River Basin. It has carried out 134 inspections and 86 samples of 54 enterprises listed in the Sanyexi River Basin, and has checked 102 unregulated enterprises in the Sanyexi River Basin. Complete the location of its discharge outlet and confirm whether it is a project listed in the Water Pollution Prevention and Control Law; and conduct water quality sampling once a month for 7 sampling points in the Sanye River Basin. The water quality of these 7 measuring stations is moderately polluted to seriously polluted. Comparing the environmental benchmarks related to the protection of human health, there were 6 stations with copper exceeding the standard and 5 stations with nickel exceeding the standard; in addition to water quality, this plan also selected 6 points in Sanye River to implement copper, chromium and lead in the sediment. , cadmium, zinc, nickel, mercury, arsenic, etc., except for cadmium, all other items have exceeded the upper and lower limit values of the sediment quality index items. Cooperate with the in-depth inspection mechanism of the Environmental Protection Bureau, select 10 manufacturers who have a record of sanctions in the past three years and are subject to stricter control of ammonia nitrogen for in-depth inspection, and invite experts and scholars to the site for inspection and guidance, collect common problems in in-depth inspections, and use the amount of dosing Adding too much is the most, and there are also situations where the operating conditions of the water treatment program are set incorrectly or the design of the treatment program is wrong, resulting in a reduction in the efficiency of the treatment program. Poor, are all factors that lead to poor wastewater treatment procedures. In the first and second half of the year, 103 community sewage and sewers under the jurisdiction of Tainan City will be inspected once respectively. 206 inspections have been completed, with a success rate of 100.0%. All the community sewage and sewers inspected comply with relevant regulations; The city’s water and fertilizer management objects were cleared and declared, and the collection and notification work, as well as the promotion of domestic sewage source pollution reduction, have been held for 5 sessions, with a total of 454 participants. In response to the abnormal situation of the surface water body reported by the public, this plan assists in the implementation A total of 3 projects were carried out for the identification of algae in water sampling, all of which were caused by the release of a large amount of organic matter, resulting in the phenomenon of eutrophication of algae proliferation.
