Abstract

The invention discloses a grease sewage treatment agent and belongs to the technical field of sewage treatment agent preparation. The grease sewage treatment agent comprises the following raw materials in parts by weight: 40 to 80 parts of enzyme preparation, 40 to 80 parts of demulsifier, 30 to 60 parts of flocculant, 30 to 60 parts of coagulant aids, 30 to 60 parts of foaming agent, 20 to 50 parts of flotation agent, 20 to 50 parts of bactericide, 10 to 20 parts of corrosion inhibition antisludging agent and 10 to 20 parts of deoxidant. The grease sewage treatment agent disclosed by the invention has the beneficial effects that existence forms of water-in-oil and oil-in-water in water can be broken to rapidly remove a large amount of SS (suspended solid), grease and COD (chemical oxygen demand); the grease sewage treatment agent is high in efficiency and has no corrosivity; secondary pollution cannot be caused to sewage in later stage, and the treatment cost is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of preparation of sewage treatment agents, in particular to a grease sewage treatment agent. 【Background technique】 [0002] Grease wastewater has the characteristics of large water volume, large fluctuations in water quality, high oil content (emulsified oil, soluble oil, phospholipids, soapstock), high COD, high content of suspended solids, strong acidity, and complex components. The current treatment method is mainly biological treatment, supplemented by necessary pretreatment and advanced physical and chemical treatment. The physical and chemical treatment method mainly relies on the addition of flocculants to polymerize the oil and suspended solids in the water body, and separates the oil and suspended solids from the water body by sedimentation or flotation. The flocculants in the background technology are mainly polymerized aluminum salts and iron salts, but in actual water bodies, oil and water ex...
