Abstract

The invention relates to a wastewater flocculation agent formulation which is characterized by the following components in parts by weight: 30-60 parts of 5%-15% polyacrylic acid liquid with the molecular weight ranging from 6 million to 8 million, 20-30 parts of 20%-30% polysilicate aluminum solution, 2-10 parts of ferrous hydroxide, 2-10 parts of diatomaceous earth, 25-35 parts of polyacrylamide, 10-12 parts of tetrasodium pyrophosphate, 10-12 parts of activated carbon, 10-12 parts of N,N-dimethyldodecylamine-N-oxide, 10-12 parts of trimanganese tetraoxide and 10-30 parts of water; and the flocculation agent provided by the invention integrates the dual effects of pH adjustment and flocculation, can adjust electroplating wastewater, realizes the flocculation of impurities in the wastewater, and has a better flocculation effect.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a waste water coagulant formula. Background technique [0002] Aluminum sulfate, aluminum chloride, polyaluminum chloride and other neutral or alkaline flocculants are usually used to remove suspended solids in wastewater. Among them, aluminum sulfate flocculants have the characteristics of low flocculation temperature, fast reaction speed and wide application range. more. In order to improve the formation of large flocs and improve the removal efficiency, this kind of flocculant usually has a better effect between pH 5-8. Therefore, when treating slightly acidic wastewater such as electroplating, cleaning and other wastewater, a large amount of acid must be added to carry out To adjust the pH, not only need to increase the acid storage equipment, but also the operation is troublesome, which increases the cost of treating alkaline wastewater. In addition, the production of ...
