Environment-friendly harmless water treatment agent

Abstract

The invention discloses an environment-friendly harmless water treatment agent which comprises polyferric sulfate, polyaluminum chloride, ethanol, ethanolamine, sodium silicate, calcium chloride, phosphorus pentoxide, natural organic acid, acrylamide, fly ash, calcium carbonate and potassium persulfate. The contents, in parts by weight, of the polyferric sulfate, the polyaluminum chloride, the ethanol, the ethanolamine, the sodium silicate, the calcium chloride, the phosphorus pentoxide, the natural organic acid, the acrylamide, the fly ash, the calcium carbonate and the potassium persulfate are as follows: 6-10 parts of the polyferric sulfate, 6-10 parts of the polyaluminum chloride, 6-10 parts of the ethanol, 4-6 parts of the ethanolamine, 4-6 parts of the sodium silicate, 10-15 parts ofthe calcium chloride, 4-6 parts of the phosphorus pentoxide, 4-6 parts of the natural organic acid, 4-6 parts of the acrylamide, 10-20 parts of the fly ash, 6-10 parts of the calcium carbonate and 6-10 parts of the potassium persulfate. The water treatment agent provided by the invention can be used for effectively carrying out scale inhibition, color removal, flocculation, disinfection and heavymetal removal on sewage, is an environment-friendly harmless water treatment agent, and is long in treatment time, good in effect, high in efficiency and easy to degrade.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an environmentally friendly and harmless water treatment agent. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of ...

AI Technical Summary

Problems solved by technology

Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: ①floating and suspended solid particles of large and small sizes; ②glue ③Pure solutions, especially industrial sewage, have heavy metal hazards inside and many harmful bacteria in the sewage. It is difficult for traditional sewage treatment agents to effectively treat them comprehensively, and multiple processes are required for scale inhibition. , decolorization, flocculation, antivirus and removal of heavy metals, the cost is high and the water treatment agent itself is not easy to degrade, which is not environmentally friendly
