Abstract

The invention relates to a flocculation agent formula for treating electroplating waste water. The flocculation agent formula is characterized by comprising the following raw materials in parts by weight: 30 to 60 parts of 5 to 15 percent polyacrylic acid liquid with the molecular weight of 6 to 8 millions; 20 to 30 parts of 20 to 30 percent polysilicate aluminium solution, 2 to 10 parts of ferrous hydroxide, 2 to 10 parts of diatomite, 25 to 35 parts of aluminum hydroxide, 10 to 12 parts of silicon dioxide, 10 to 12 parts of active carbon, 10 to 12 parts of N,N-dimethyldodecylamine-N-oxide, 10 to 12 parts of manganous-manganic oxide, and 10 to 30 parts of water. The flocculation agent provided by the invention integrates dual effects of adjusting PH and flocculating, can realize the flocculation of impurities in the waste water while adjusting the electroplating waste water, and is better in flocculation effect.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a coagulant formula for electroplating wastewater treatment. 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 a...
