Abstract

The invention relates to a composite purifying agent used for purifying sewage in a river channel, which comprises the following components by weight: 40% to 90% of benzalkonium chloride, 5% to 25% of polymerization ferric sulfate, 4% to 15% of polyacrylamide, 0.5% to 10% of activated carbon and 0.5% to 10% of effervescent disintegrant. The composite purifying agent further comprises an organic matter degradation agent occupying 0.5-5wt% of the total dose of the composite purifying agent. The composite purifying agent is easy to decompose, fewer in dosage, free of residual, free of secondarypollution, simple and convenient in operation, short in time required to purify water, capable of effectively removing bacteria and algae, degrading organic matter, precipitating floating floc and the like, capable of effectively removing chemical oxygen demand, total nitrogen, total phosphorus and the like, remarkable in turbidity and capable of effectively improving PH and chromaticity of waterbody, thereby being an effective water purifying agent of water bodies such as river channels, lakes and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a composite purifying agent for purifying river sewage. Background technique [0002] With the continuous development of human society and the improvement of urbanization and industrialization, the aggravation of water pollution has become a global problem that needs to be solved urgently. For our country, in the modernization drive, how to solve the water problem is an urgent and important issue. [0003] The traditional sewage treatment technology generally takes a long time to treat and the investment cost is high, which can no longer meet the needs of modern life. However, some sewage treatment methods with better effects require large-scale equipment and huge funds, which are generally difficult for small and medium-sized enterprises. [0004] At present, there are mainly adsorption methods for the treatment of refractory organic wastewater. Ads...
