Processing material for chemical wastewater, preparation method and system, and control method

Abstract

The invention belongs to the field of chemical industrial pollution government, and discloses a processing material for chemical wastewater, a preparation method, a system, and a control method. The processing material comprises is prepared from the following materials: 6-8 parts of molecular sieves, 11-13 parts of sulfonated coal, 3-6 parts of polyferric sulfate, 8-11 parts of polyacrylamide, 3%of nitrobacteria wastewater, 9-14 parts of activated carbon, 2-7 parts of soy protein, 5-8 parts of attapulgite, 2-6 parts of sodium lignin sulfonate, 6-7 parts of sodium benzenesulfonate, 5-10 partsof maleic anhydride grafted polypropylene, 3-6 parts of nanometer particle inorganic material, 2-7 parts of bentonite and 3-8 parts of sodium sulfate. According to the processing material for chemicalwastewater, heavy metal ions in water can be effectively neutralized, water quality is purified, and meanwhile, the processing material has a good adsorption function for suspended solids. Water quality is purified, meanwhile, the nitrobacteria can be added to carry out biological purification, and excessive nitrides in the wastewater are decomposed.

Description

technical field [0001] The invention belongs to the field of chemical pollution control, and in particular relates to a treatment material, preparation method, system and control method for chemical wastewater. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Chemical wastewater is the process wastewater, cooling water, waste washing water, equipment and site washing water and other wastewater discharged in chemical production. If the waste water is discharged without treatment, it will cause different properties and different degrees of pollution of the water body, thereby endangering human health and affecting industrial and agricultural production. Chemical wastewater generally has the following characteristics: (1) The water quality is complex, with many by-products, and the reaction raw materials are often solvent-like substances or compounds with ring structures, which increases the difficulty o...

Problems solved by technology

If the waste water is discharged without treatment, it will cause different properties and degrees of pollution to the water body, thereby endangering human health and affecting industrial and agricultural production.

Chemical wastewater generally has the following characteristics: (1) The water quality is complex, with many by-products, and the reaction raw materials are often solvent-like substances or compounds with ring structures, which increases the difficulty of wastewater treatment; (2) The pollutant content in wastewater is high. It is caused by the incomplete reaction of raw materials and the entry of a large amount of solvent media used in raw materials or production into the wastewater system; (3) There are many toxic and harmful substances, and many organic pollutants in fine chemical wastewater are toxic and harmful to microorganisms

(4) There are many biodegradable substances, the B / C ratio is low, and the biodegradability is poor; (5) The chroma of wastewater is high

[0008] The existing technology has low degradation efficiency for industrial wastewater, high chroma of wastewater is difficult to purify, and cannot meet the needs of producers and processors

[0009] The preparation system of the prior art has a low degree of intelligent operation, is inconvenient to operate, and the quality of the obtained product is poor

[0010] The current treatment methods for low-concentration refractory organic industrial wastewater have high operating costs and low treatment efficiency.
