Embodiment 1

[0018] 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 R24m rake type thickening tank of coal preparation plant. Put the coal slime water into the R8m 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 R8m 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 4P 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 test run once hour, the amount of treated coal slime water is 690m 3 Use 200kg of treating agent of the present invention, promptly every cubic meter of...

Embodiment 2

[0020] Embodiment 2, the waste water of a certain oil production plant adopts the present invention to be processed, and the processing result is as shown in the following table:

[0021] project pH SS(mg / L) COD (mg / L) Oil (mg / L) Oilfield raw water sample 7.5 144.2 890 334 Clear water sample after coagulation and settlement 7.2 58 64 4.89.

Abstract

The invention discloses a detergent which is characterized in that the detergent contains Al<+++>, Fe<+++>, Mg<++> and a small amount of Mn<2+> and lithopone, the Al<+++> accounts for 30-50%, Fe<+++> accounts for 10-30%, Mg<++> accounts for 30-50%, and the detergent is prepared by mixing by adopting a general method. A certain amount of water is taken, proper amounts of aluminum sulfate (the purity is 95% or more), ferric sulfate (the purity is 95% or more) and magnesium sulfate (the purity is 95% or more), manganese sulfate (the purity is 95% or more) and lithopone are added, and uniform stirring is conducted at room temperature to a complete dissolution state, wherein the optimal ratios of the contents of Al<+++>, Fe<+++> and Mg<++> are as follows: the content of Al<+++> accounts for 40%, the content of Fe<+++> accounts for 10%, the content of Mg<++> accounts for 40%, the content of Mn<2+> accounts for 6% and the content of lithopone accounts for 4%, and the percentage is weight percentage.

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 surrounding liquid to remove the pollutants in the water. A method of contamination. At present, in some industries, such as coal slime water, oily wastewater from oil fields, printing and dyeing wastewater, papermaking wastewater, etc., the chemicals used have poor treatment effects, slow settling speed, high cost of chemicals, 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 a...
