Question 8: What are the contents of the industrial wastewater testing project? Abstract: Industrial wastewater includes production wastewater and production sewage, which refers to wastewater and waste liquid produced in industrial production, including industrial raw materials, intermediate products, by-products and pollutants produced in the production process. Water discharged during production.
Harm of industrial wastewater
The increasingly serious water pollution has posed a great threat to human survival and safety. Heavy industry wastewater, which has become the sustainable development of human health, economy and society, includes production wastewater and production sewage, which refers to wastewater and waste liquid produced in industrial production, including industrial raw materials, intermediate products, by-products and pollutants produced in the production process. Water discharged during production.
Harm of industrial wastewater
The increasingly serious water pollution poses a great threat to the survival and safety of human beings and becomes the main obstacle to the sustainable development of human health, economy and society. According to the survey of international authoritative organizations, in developing countries, 80% of various diseases are spread by drinking unsanitary water, which causes at least 20 million deaths worldwide every year. Therefore, industrial water pollution is called the world's number one killer.
(1) Whether the discharge exceeds the standard. Mainly check whether the COD in supervisory monitoring results, online monitoring results and factory effluent monitoring results exceeds the standard, and also pay attention to other indicators, such as total phosphorus and ammonia nitrogen. If it exceeds the standard, there must be corresponding detection documents; If the monitoring results exceed the standard by more than 30%, we should carefully find out the reasons and correct them.
(2) Whether the monitoring frequency meets the requirements. On-line monitoring device should operate normally. Supervision and monitoring should be at least once every quarter. The factory basically has to ensure that it is monitored once a day.
(3) Check the consistency of supervisory monitoring data with online and factory monitoring data on the day of sampling.
(4) Accounting removal efficiency. The closer the influent concentration is to the design concentration, the higher the removal rate of sewage treatment facilities.
(5) influent concentration. The abnormal increase or decrease and excessive fluctuation of influent concentration should be paid attention to and explained.
