Problems solved by technology

[0002] At present, with the development of industrialization, there are more and more production sewage, and arbitrary discharge will cause adverse effects on the environment. In order to improve the environment, sewage treatment technology has emerged as the times require. Or the water quality requirements for reuse, and the process of purifying it, sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Into the daily life of ordinary people; sewage treatment agent has become an important part of sewage treatment, some sewage treatment agents are not effective, and the treatment agent with good sewage treatment effect is high in cost

Abstract

The invention discloses a sewage processing agent and a preparation method thereof. The sewage processing agent is prepared from the following raw materials in parts by weight: 30 to 40 parts of cationic flocculant, 30 to 40 parts of sodium chloride, 10 to 15 parts of lithopone, 5 to 10 parts of polyethylene imine, 5 to 10 parts of critic acid, 8 to 10 parts of zinc oxide, 4 to 6 parts of active carbon, 5 to 10 parts of polymeric silicate aluminum sulfate, 5 to 10 parts of polyacrylamide, 20 to 30 parts of composite synergist, 8 to 10 parts of corn starch, and 50 to 100 parts of deionized water, wherein the composite synergist is one or more of ferric chloride, sodium lignosulfonate, polymeric aluminum chloride, and sodium acetate. The provided sewage processing agent can effectively remove oil stain, suspensions, COD and BOD of sewage, and prominently improve the clarity of water.
