A kind of 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 made of the following components according to the mass percentage: sodium hypochlorite: 99% to 99.5%, potassium permanganate: 0.05% to 0.2%, and potassium ferrate : 0.15% ~ 0.3%, polyferric sulfate: 0.3% ~ 0.5%. The preparation method is as follows: add 99% to 99.5% sodium hypochlorite in the reaction kettle, stir until the sodium hypochlorite dissolves, add 0.05% to 0.2% potassium permanganate, stir for 0.5 to 1 hour, until completely dissolved, add 0.15% ~0.3% potassium ferrate, stir for 0.5-1 hour, finally add 0.3%-0.5% polyferric sulfate, stir for 0.5-1 hour until completely dissolved to obtain a purple-red liquid product, the above components are mass percentages. The beneficial effects of the present invention are: through the interaction of three strong oxidants and the different timeliness of organic matter, combined with the flocculation of polyferric sulfate, the removal rate of organic pollutants in water can reach up to 95%, and the cost is low. Only 1 / 10 of ordinary remover, high treatment 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 ...

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
