- Abstract:
- The upgrading and reconstruction project of a sewage treatment plant with scale of 5 000 m3/d in Guangdong Province has the problems such as land shortage and investment limitation, and it also needs to meet the requirement of non-stop production during the renovation process. Therefore, the micro-flocculation and filtration advanced treatment unit was added to the original CASS treatment process, and the disinfection system was upgraded. The purpose of the secondary contact flocculation between microflocs and filter material and filtration and interception of pollutants were realized by using micro-flocculation combined with high-speed deep filtration technology packed with special high porosity and large contaminant capacity media. After the upgrading of the project, the effluent quality stably met the discharge standard, and the operating cost only increased by 0.132 yuan/m3. The application of this technology in the upgrading project has the advantages of less footprint area, lower investment, short construction period, simplified system and convenient operation and maintenance, and it is worthy of further promotion.
