Abstract

The invention relates to an oily water cleaning agent and a preparation method thereof. The oily water cleaning agent contains the following components in parts by weight: 15-30 parts of polyaluminum chloride, 5-12 parts of anionic polyacrylamide, 7-16 parts of lime, 3-10 parts of sodium hypochlorite, 3-8 parts of sodium lignosulfonate, 3-7 parts of diammonium hydrogen phosphate and 5-15 parts of sodium benzenesulfonate. The oily water cleaning agent provided by the invention has a very strong flocculation function, has good sterilizing effects and can reduce the oil content in wastewater from 120mg / L below 8mg / L and the suspended matter content from 285mg / L below 15mg / L.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to an oily sewage purifier and a preparation method thereof. Background technique [0002] At present, domestic water consumption and industrial water consumption are increasing, and the amount of wastewater discharged is also increasing. Most of these wastewaters contain oil pollution. When these wastewaters are discharged into rivers and lakes, they will cause pollution and affect human beings and ecological balance. Therefore, these wastewaters must be treated before being discharged. There are few types of purifiers for treating oily wastewater, and their purification effect is relatively simple, which cannot meet the needs of wastewater treatment. Contents of the invention [0003] Technical problem to be solved: Aiming at the shortcomings of existing oily wastewater purifiers with few types and single effect, the present invention provides an oily wastewater purifier and a p...
