Abstract

The invention discloses a sewage purifying agent for improving sewage purification effect, which comprises the following components in parts by weight: diatomite, 45-55 parts; light calcium carbonate, 30-40 parts; vermiculite powder, 35-45 parts powder; dickite, 25-35 parts; sericite powder, 10-20 parts; quartz sand, 15-25 parts; natural gypsum, 15-25 parts; zinc stearate, 4-8 parts; carboxymethyl fiber A mixture of cellulose and sodium alginate, 5-7 parts; the weight ratio of the carboxymethyl cellulose and sodium alginate is 4-6:1. The sewage purifying agent provided by the invention can efficiently degrade organic matter in sewage, significantly reduce COD value and total nitrogen content, and improve sewage purification effect. The preparation method of the sewage purifying agent of the present invention is simple, does not need large-scale equipment, can be produced on a large scale, and has low cost.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to sewage treatment, in particular to a sewage purifying agent for improving sewage purification effect, which is used for sewage treatment. Background technique [0002] At present, many factories in our country, especially chemical factories, paper mills, pharmaceutical factories, sugar bran factories, starch factories, etc., discharge wastewater in the production process with varying degrees of toxicity, which seriously pollutes the environment and endangers people. The health of the population has become a serious constraint on economic development. [0003] There are two main methods of sewage treatment: one is the physical and chemical method, that is, the coagulation method; the other is the biochemical method. Physicochemical method has a good effect on removing chroma, heavy metals and phosphorus. The biochemical method has a good removal effect on organic pollutants,...
