Embodiment 3

[0022] Embodiment 3 is the best implementation mode.

[0023] Performance Testing:

[0024] The sewage treatment agent prepared in Examples 1-5 is used to treat landfill leachate and chemical waste water respectively, and then the method for detecting COD, ammonia nitrogen and suspended matter is carried out on the landfill leachate and chemical waste water before and after treatment. Sampling analysis and testing were carried out at three sampling times. The contents of the above-mentioned pollutants in the landfill leachate before and after treatment are shown in Table 2, and the contents of the above-mentioned pollutants in the chemical wastewater before and after treatment are shown in Table 3.

[0025] Table 2 shows the content of the above pollutants before and after treatment of landfill leachate

[0026]

[0027] Table 3 is the content of the above pollutants before and after the treatment of chemical wastewater

Abstract

The invention relates to the technical field of sewage treatment and particularly relates to an industrial wastewater treating agent. The industrial wastewater treating agent comprises the following components in parts by mass: 0.8-3 parts of polyacrylamide, 25-35 parts of aluminium polychlorid, 25-55 parts of alums, 3-8 parts of iron trichloride, 0.8-3.4 parts of polymeric ferric sulfate, 1.2-2.5 parts of a coagulant aid, 2-10 parts of plant fiber, 10-30 parts of coal ash, 0.8-2.5 parts of sodium silicate, 2.5-5 parts of sodium sulfite, 0.5-3.5 parts of sodium hypochlorite, 5-10 parts of hydrogen peroxide, 8-15 parts of a sodium carbonate-sodium bicarbonate buffer system and 10-20 parts of sodium-based bentonite. The treating agent has the beneficial effects of wide treated pollutant range, good effect, wide production raw material source, environmental friendliness, no toxicity, good discharged water quality, short process flow, and high process operating safety. The treating agent disclosed by the invention can treat various kinds of wastewater such as chemical wastewater produced in oil fields, mining, steel, electroplating wastewater, dyes, pesticides, wine-making and chemical engineering, and sanitary sewage, papermaking wastewater, river and lake water, rubbish seeping water, leather-making wastewater, and the like; and the treating agent is good in treatment effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an industrial sewage treatment agent. Background technique [0002] my country is a country with a shortage of water resources, how to alleviate the shortage of water resources and pollution has become an urgent problem. [0003] At present, the coagulants commonly used in sewage treatment agents mainly include inorganic flocculants and organic polymer flocculants. Inorganic flocculants are a new type of water treatment agents developed on the basis of traditional aluminum salt and iron salt flocculants. With more and more types and quantities of wastewater discharged from factories, and the water quality becoming more and more complex, pure aluminum and iron salt inorganic polymer flocculants can no longer meet the increasingly high requirements in the wastewater treatment process. Therefore, the research on polysilicate iron aluminum coagulant, polyaluminum iron silic...
