Abstract

The invention relates to a black-odor river channel treatment process. The process includes 1), black-odor river channel pretreatment, namely adding a polymer aluminum chloride solution and palladiumcharcoal to channel sewage, pumping the mixture to a sedimentation tank statically after mixing, adding the alkaline polymer aluminum chloride solution and palladium charcoal to a supernatant, pumpingthe mixture to the sedimentation tank statically after mixing, adding a polyacrylamide flocculant aqueous solution and palladium charcoal to clear liquid, pumping the clear liquid to the sedimentation tank statically after even mixing, and collecting flocculate in the sedimentation tank; 2), odor treatment, namely treating the flocculate collected in the step 1), in the presence of air to reach the discharge standard under the condition of heating and pressure; 3), river channel sludge treatment, namely forming the river channel sludge by extrusion to obtain a catalyst support material via heat treatment. The black-odor river channel treatment process has the advantages of high odor removal efficiency, high added value and the like.

Description

technical field [0001] The invention relates to the field of black and odorous river sewage treatment, in particular to a black and odorous river treatment process. Background technique [0002] With the rapid development of the national economy, the pollution of river water is becoming more and more serious. The river water not only has a lot of suspended solids, but also the water is smelly, which seriously affects the cleanliness and self-purification ability of the river. It is necessary to treat the river water regularly. However, the river is black and smelly. The treatment of water bodies and the resource utilization technology of river sludge are current industry problems that need to be solved urgently. Therefore, subject technical experts in various fields conduct research on how to resourcefully treat river water and sludge. Due to the disadvantages of high treatment cost, low treatment efficiency and low added value of products in ordinary river black and odorou...
