Problems solved by technology

[0003] After the completion of many chemical sewage treatment facilities, the operating costs are high, even exceeding the capacity of the sewage discharge enterprises, and the expensive facilities have become decorations.
After chemical companies spend huge sums of money to build sewage treatment stations, the quality of the effluent water cannot meet the standards or the quality of the sewage is unstable, which cannot meet the requirements of the environmental protection department, thus bringing huge losses to the company

Abstract

The invention discloses a primary physicochemical enhanced treatment coagulant for chemical waste water and relates to the technical field of chemical waste water treatment. The coagulant is prepared from, by weight, 10 kg to 18 kg of ferric sulfate, 8 kg to 12 kg of aluminum polysilicate, 4 kg to 9 kg of sodium lignosulfonate, 3 kg to 7 kg of carbon nanotubes, 5 kg to 8 kg of nano-zinc oxide, 3 kg to 6 kg of activated carbon fiber, 2 kg to 5 kg of polyvinyl alcohol, 2 kg to 5 kg of organic montmorillonite, 3 kg to 8 kg of phenolic resin, 1 kg to 4 kg of rapeseed oil, 1.5 kg to 3 kg of gas carbon black, 0.5 kg to 2 kg of propolis, 2 kg to 5 kg of calcium stearate and 8 kg to 12 kg of iron powder. According to the coagulant, chemical waste water is treated jointly by the carbon nanotubes, the nano-zinc oxide, the activated carbon fiber and other physicochemical reagents, the treatment speed is high, COD and BOD of the waste water can be effectively reduced, and organic matter in the waste water can be effectively removed.

Description

Technical field: [0001] The invention relates to the technical field of chemical sewage treatment, in particular to a coagulant for primary physical and chemical enhanced treatment of chemical sewage. Background technique: [0002] The most important characteristics of chemical wastewater are: large changes in water quality and quantity, low B / C ratio, and poor biodegradability. General chemical sewage also has high chroma, and the pH value is mostly strongly acidic or strongly alkaline, so it is difficult to treat, and the treatment of chemical sewage has become a worldwide problem. [0003] After the completion of many chemical sewage treatment facilities, the operating costs are high, even exceeding the capacity of the sewage enterprises, and the expensive facilities have become decorations. After chemical companies spend huge sums of money to build sewage treatment stations, the quality of effluent water cannot meet the standard or the quality of sewage is unstable, whi...
