Abstract

The invention discloses a sewage purifying agent, which comprises the following ingredients (by weight): 45-55 parts of bentonite, 30-40 parts of heavy calcium carbonate, 35-45 parts of silica micropowder, 25-35 parts of clay, 10-20 parts of sericite powder, 15-25 parts of quartz sand, 15-25 parts of zeolite, 4-8 parts of calcium stearate, and 5-7 parts of a mixture of iron ore and cellulose. The weight ratio of iron ore to cellulose is 4-6:1. By the use of the sewage purifying agent provided by the invention, organic matter in sewage can be efficiently degraded, COD value and total nitrogen content can be remarkably decreased, and sewage purification effect can be enhanced. A preparation method of the sewage purifying agent is simple; no large-scale equipment is required; the product is suitable for large-scale production; and cost is low.

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. Background technique [0002] 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, nitrogen and phosphorus, but the removal rate of COD is low, the decolorization effect is poor, and a large amount of sludge will be generated, causing secondary environmental pollution. The general biochemical method requires that the wastewater has good biodegradability, the proportion of various nutrients is coordinated, the concentration is appropriate, and the concentration of substances that inhibit biological growth is not higher than the range that microorganisms...
