Abstract

The invention discloses a water purifying agent for treating petroleum refining wastewater. The water purifying agent comprises, by weight, 25 to 40 parts of polyaluminum ferric chloride, 10 to 30 parts of aluminum chloride, 6 to 20 parts of ferrous sulfate, 15 to 20 parts of magnesium chloride, 10 to 20 parts of sodium sulfate, 2 to 4 parts of bacterial powder, 2 to 6 parts of an enzyme preparation, 15 to 20 parts of diatomite, 15 to 35 parts of Chinese medical stone and 3 to 15 parts of a fruit shell filter material. The water purifying agent for treating petroleum refining wastewater realizes effective treatment of wastewater, substantially decreases the discharge amount of COD, has the characteristics of good water purification effect, fast water purification speed, high security and no secondary pollution, reduces the discharge of sewage, improves the quality of wastewater, enables treated water to have high transparency and can be recycled.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a water purifying agent used for the treatment of petroleum refining wastewater. Background technique [0002] Since modern times, with the continuous development of the petroleum industry, especially in the era of the automobile industry, the amount of crude oil imported by my country has continued to increase each year, and the production scale of domestic petroleum refineries has continued to expand. The petroleum refinery wastewater discharged by these petroleum refineries has become more and more More and more, the impact on the environment is also increasing. However, the current treatment effect of petroleum refining wastewater is relatively poor, and it is difficult to meet the needs of modern production. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the present invention provides a water purifying agent for...
