Abstract

The invention discloses a low-cost domestic sewage treatment agent. The low-cost domestic sewage treatment agent contains polymerized ferric chloride, polyacrylamide, polyethyleneimine, bentonite, sodium chloride, lime, an adsorbate, sodium carbonate and a pH regulator. The treatment agent has the advantages that domestic sewage can be treated effectively, the cost is low, the effect is good, the pollution to ecological environment caused by the domestic sewage is alleviated, the removal ratio of suspended solids in the sewage reaches 98.3%, the BOD (Biochemical Oxygen Demand) removal ratio is 95.2%, the COD (Chemical Oxygen Demand) removal ratio is 96.8%, and the chroma is 5.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a low-cost domestic sewage treatment agent. Background technique [0002] With the continuous improvement of people's living standards, human water consumption is also increasing, and domestic sewage is also increasing. If sewage is discharged into nature without treatment, it will inevitably pollute nature. Therefore, how to properly treat sewage has become a problem. to the survival of future generations. Some of the existing domestic sewage treatment uses physical methods that consume more manpower and material resources, and some use sewage treatment agents for chemical treatment, but the cost is high and the treatment effect is not satisfactory. Contents of the invention [0003] The object of the present invention is to provide a low-cost domestic sewage treatment agent for the above-mentioned existing defects. The treatment agent can effectively treat domestic...
