CGAN high ammonia nitrogen sewage
Ammonia nitrogen wastewater mainly comes from coal chemical, chemical fertilizer, coking, petrochemical, pharmaceutical, food and other industries. A large amount of ammonia nitrogen wastewater discharged into the water body not only causes eutrophication of the water body, causes black body odor, but also increases the difficulty and cost of water treatment. And biological damage. CGAN technology is a new technology developed based on our company's patented technologies (ZL 201210051165.2, ZL 200820096218.1), and has won the Guiyang Excellent Patent Award. This technology optimizes the water quality characteristics of high ammonia nitrogen wastewater based on traditional processes, and systematically integrates pretreatment, activated sludge method, biofilm method and advanced treatment technology to achieve short-range nitrification and reduce drug consumption during ammonia nitrogen degradation. And electricity consumption, improve ammonia nitrogen treatment efficiency, and achieve sewage treatment standards.
This technology has been successfully applied in Bangladesh Sharjah Fertilizer Plant, Hong Kong Wuyuan, Kaiphos Group, Meifeng Group, Danhua Group and other enterprises, and achieved good results.
The process flow is as follows:
