Wastewater Treatment of MMA High Organic Matter and High Cyanide Production in Chemical Enterprises
In order to improve the treatment efficiency of MMA high organic matter and high cyanide wastewater,this article designs a wastewater treatment technology for chemical enterprises to produce MMA high organic matter and high cyanide.MMA wastewater is divided into two parts:pre-treatment and biochemical treatment.In the pre-treatment stage,cyanide and organic matter are treated,and the pH value of the wastewater is adjusted to meet the effluent standard.In the biochemical treatment stage,nitrification solution is used to treat NH3-N,cyanide,and other pollutants such as COD in wastewater.By controlling pH value and iron carbon mass ratio,efficient COD treatment can be achieved.After using ozone catalytic oxidation technology,COD changed from 26 000 mg/L to 150 mg/L;NH3-N changed from 150 mg/L to 5 mg/L;the cyanide content may be negligible;the pH value increased from 2.5 to 6.8,indicating a better wastewater treatment effect.Ozone catalytic oxidation technology plays an important role in the treatment of MMA high organic matter and high cyanide wastewater,and can meet the production needs of chemical enterprises.
