Municipal wastewater, including domestic sewage, industrial wastewater and runoff sewage, etc., is collected by the urban drainage network and transported to the wastewater treatment plant for treatment. Urban wastewater treatment process, should be used in a variety of forms according to local conditions, according to the use of urban sewage or discharge destination at the same time to consider the natural purification of water bodies and the purification of sewage in the process of utilization. Determine the degree of treatment of wastewater and the corresponding treatment process. Treated sewage, whether for industrial, agricultural or external discharge, should meet the national standards.Municipal wastewater treatment is divided into three levels, namely, primary treatment (mechanical treatment), secondary treatment (biological treatment), and tertiary treatment (advanced treatment). The primary treatment mainly uses grids, sand settling tanks, sedimentation tanks and other structures to remove the insoluble suspended matter in the sewage. The secondary treatment mainly removes colloids and dissolved organic matter from the effluent of the primary sedimentation tank. Typical equipment is biological aeration tank (or biofilter) and secondary sedimentation tank. Tertiary treatment mainly removes nutrients (nitrogen and phosphorus) and other hard-to-degrade substances from the secondary effluent. The main methods are flocculation, filtration, adsorption, ion exchange and other physical and chemical methods. The purpose of tertiary treatment is to avoid eutrophication of water bodies or reuse water. Municipal wastewater treatment. Generally, the primary treatment is to be treated. Second-stage treatment as the main body. Tertiary treatment is rarely used.
In the process of municipal wastewater treatment, polyacrylamide is needed, and the specific choice of suitable polyacrylamide needs to be selected according to the selection experiment. The effect of polyacrylamide treatment is mainly depends on the degree of fit, it is accurate model selection or not, which is closely related to the size of the selection range, the wider the range, the more models, it is more likely to choose the right model. Guangdong Shouxin Environmental Protection Materials Technology Co., Ltd. is a global polyacrylamide brand with stable quality, after more than ten years of development Shouxin brand polyacrylamide has two advantages are more obvious：
1. More models of polyacrylamide: There are 107 different models of polyacrylamide, which can provide customers with accurate selection experiments and pick out more cost-effective polyacrylamide models for customers.
2. Stability of polyacrylamide products: As Guangdong Shouxin Environmental Protection Materials Technology Co., Ltd. is a global polyacrylamide brand with stable quality, there is less concern about the production cost, and it will strictly control the quality, and through professional technical engineers and advanced testing equipment, it will do strict double supervision and testing when it comes to incoming and outgoing products, and the qualified products will be put into storage to ensure the stability of the products.
It is also due to the above advantages that Shouxin's polyacrylamide is favored by the majority of municipal wastewater treatment customers.
