Embodiment Construction

[0006] Composition standards and preparation methods of medicines:

[0007] 1. Drug No. 1: crush quicklime into powder, mix it with sodium hydroxide 1:1, and then dilute it with tap water at a ratio of 1:4 to form a liquid. The pH value is 14.

[0008] 2. Drug No. 2: After mixing half of the solid polyaluminum chloride and polysilicon chloride together, dilute it with tap water at a rate of 1:3. Then use 30% concentration of liquid hydrochloric acid and coal-fired boiler electrostatic precipitator dry dust in a ratio of 10:1 to prepare and soak, then add polyaluminum chloride and polysilicon chloride liquid to adjust the pH value within 2-3.

[0009] 3. Drug No. 3: Mix 1 / 3 of Japanese-made PAM with a molecular weight of 12 million to 16 million, domestic polyacrylamide with a molecular weight of 8 million, and polycyclic aromatic hydrocarbons with a molecular weight of 6 million, and dilute with 0.25mg‰ or 1mg‰ of tap water to prepare liquid.

[0010] 4. Drug No. 4: Dilute ...

Abstract

This invention relates to chemicals for removing sludge from industrial wastewater. This inventive chemical is composed of various kinds of chemical agents being proportionally prepared and diluted into liquid. When utilization, the same is dissolved in wastewater for three or four times of different periods. The inventive chemical can destroy the chemical bonds in wastewater, Change the properties of the waste water, so making the suspension being separated from water thoroughly and removing COD, SS, ammonia-nitrogen and having reasonable pH value, meeting the effluent standards issued by environmental protection department, or being reused to production. This invention method and chemicals can not produce secondary pollution.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment and purification. Background technique [0002] The production wastewater discharged from industrial production has brought greater pressure to environmental governance. Using the original anaerobic, aeration, amplitude flow, sedimentation or biological methods to treat industrial wastewater can no longer adapt to the current rapid industrial development. environmental hazards. Contents of the invention [0003] The purpose of the present invention is to solve the problem of separation and purification of pollutants and water in industrial wastewater in a short period of three minutes, so as to achieve the discharge or reuse of purified water quality standards, and the use of medicaments so that the separated waste residue will not cause pollution to the environment. Secondary pollution. [0004] The technical proposal of the present invention is: adopt a kind of industrial waste...
