Abstract: 98% of the wastewater in the dairy industry belongs to the whey washing wastewater, the main components of the wastewater are protein, fat, dry matter, etc., and the biochemical performance is particularly good. The wastewater treatment process of dairy products is hydrolytic acidification + anaerobic + good nutrition process. In general dairy production enterprises, the average COD of wastewater inlet is 2000-2500mg/l, and the anaerobic part of the wastewater treatment process can produce a large amount of biogas. In the early design of wastewater treatment of dairy products, most of them were discharged by direct combustion of the torch, which not only wastes resources, but also has ecological environment and safety production risks. This paper considers that a set of biogas recovery and treatment system and biogas boiler system can be designed to realize resource recovery and utilization, which can not only save energy, but also reduce the total carbon emission of enterprises. After analyzing the sewage index of Mengniu Dairy (Maanshan) Co., LTD., this paper decided to first collect the gas generated in the anaerobic stage by using biogas recovery system, then use biogas desulfurization device to remove the sulfur in the gas, and finally enter the biogas boiler for combustion and output steam for utilization. The above treatment process can effectively utilize biogas and achieve energy saving and consumption reduction.Abstract: 98% of the wastewater in the dairy industry belongs to the whey washing wastewater, the main components of the wastewater are protein, fat, dry matter, etc., and the biochemical performance is particularly good.

Abstract: In recent years, with the rapid development of China's industry, the risks of new pollutants have become increasingly apparent. From China's long-standing emphasis on "attaching importance to the governance of new pollutants" to the Ministry of Ecology and Environment's issuance of the "List of Key Controlled New Pollutants (2023 Edition)" in conjunction with relevant departments, screening, monitoring, and risk assessment of new pollutants in China have become particularly important. This article mainly introduces the continuous progress China has made in screening and identifying strategies and analytical methodologies, developing research strategies from "substance to risk" and "risk to substance", and building a high-throughput multifunctional group toxicity analysis system (ITA). It also establishes a methodological framework for evaluating the environmental behavior of potential pollutants. Currently, there are four types of new pollutants that have received widespread attention internationally, including persistent organic pollutants, endocrine disruptors, antibiotics, and microplastics. According to China's current research status and development trends of new pollutants, combined with the latest research progress on new pollutants, several reflections and suggestions are proposed, including strengthening research and technical exchanges on new pollutants, improving the investigation and monitoring technology system, improving laws and regulations, and establishing a sound standard and specification system.Abstract: In recent years, with the rapid development of China's industry, the risks of new pollutants have become increasingly apparent.
