High-efficiency multifunctional remover and preparation method thereof

Abstract

The invention relates to a high-efficiency multifunctional remover and a preparation method thereof. The remover is prepared from 99-99.5mass% of sodium hypochlorite, 0.05-0.2mass% of potassium permanganate, 0.15-0.3mass% of potassium ferrate and 0.3-0.5mass% of polyferric sulfate. The preparation method of the remover comprises the following steps: adding 99-99.5mass% of sodium hypochlorite into a reaction kettle, stirring for dissolving sodium hypochlorite, adding 0.05-0.2mass% of potassium permanganate, stirring for 0.5-1h until complete dissolving, adding 0.15-0.3mass% of potassium ferrate, stirring and reacting for 0.5-1h, finally adding 0.3-0.5mass% of polyferric sulfate, and stirring for 0.5-1h until complete dissolving in order to obtain a purple red liquid product. The interaction of three strong oxidants, different timeliness to organic matters and the flocculation of polyferric sulfate allow the highest removal rate of organic pollutants to reach 95% and the cost to only account for 1 / 10 of the cost of an ordinary remover, so the remover provided by the invention has the advantages of high processing efficiency and low cost.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a high-efficiency multifunctional remover and a preparation method thereof. Background technique [0002] With the rapid development of my country's chemical industry, various new chemical products are widely used, especially in heavy polluting industries such as medicine, chemical industry, electroplating, printing and dyeing, etc., while improving product quality, it also brings increasingly serious environmental pollution. The problems are mainly manifested in: the concentration of organic pollutants in wastewater is high, the structure is stable, and the biochemical properties are poor. It is difficult to achieve standard discharge by conventional processes, and the treatment cost is high, which brings great pressure on enterprises to save energy and reduce emissions. [0003] In order to curb the trend of environmental deterioration, the state has carried ...

AI Technical Summary

Problems solved by technology

But in terms of the overall level, the current sewage treatment technology in the domestic environmental protection industry is relatively backward. The removers used in traditional water treatment have the ability to remove pollutants in water such as chroma, COD, ammonia nitrogen, total phosphorus, and some heavy metals. Relatively single, even some removers still have the problem of no actual processing capacity, which is far from the expected effect, and ordinary removers also have problems such as high processing cost and low processing efficiency, so a new generation of high-efficiency multi-functional remover is developed it seems necessary
