Embodiment 1

[0016] Embodiment 1 uses the above sewage treatment agent to carry out treatment test to certain mine coal slime water, and this coal slime water is the middle part water in the φ 24m rake type thickening pond of coal preparation plant. Put the coal slime water into the φ8m concentrator, add the sewage treatment agent of the present invention into the pipe that has been driven in, and the coal slime water after the dosing will settle in the φ8m thickener. After precipitation, the supernatant overflows to the clear water tank and is reused for coal washing. After sedimentation, the flocs are pumped to a belt filter press with a diaphragm pump for dehydration. The test uses a 4Ps water pump to pump coal slime water with a flow rate of 70m 3 / h, adding the treatment agent of the present invention to control the flow rate is 0.7 ~ 0.8m 3 / h, the test runs for 8 to 12 hours at a time, and the amount of coal slime water treated is 690m 3 Use 200kg of treating agent of the present...

Abstract

The present invention relates to environment protection technology. The sewage treating agent contains Al iron, Fe ion, Mg iron, Mn ion and lithopone, and is compounded by mixing water, aluminium sulfate, ferric sulfate, magnesium sulfate, manganese sulfate and lithopone through stirring for complete dissolving. It has the advantages of wide use range, high deposit rate, good quality of treated water, low cost, no corrosion to steel structure, no toxicity, no pollution and relatively high safety, and it may be widely used for effluent treatment in oil field, coal mine, textile mill, printing and dyeing mill, etc. and city sewage treatment.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection. Background technique [0002] The chemical precipitation method is widely used in sewage treatment. It is to add some chemical agents to the waste water to make it chemically react with the pollutants in the waste water to form insoluble solid products, and then separate the solid and liquid to remove the water. A method of contamination. At present, the chemicals used in some industries, such as coal slime water, oily wastewater, printing and dyeing wastewater, and papermaking wastewater, have poor treatment effects, slow settling speed, high chemical costs, and some enterprises have caused serious corrosion of equipment. [0003] During the production of coal mines, a large amount of slime water is produced, and if the water is not treated in time, it will cause serious pollution. The existing coal slime water treatment method mostly adopts chemical treatment, adding polyalu...
