氯碱化工企业高盐废水治理

Treatment of high salinity wastewater in chlor-alkali chemical industry enterprises

废水的高盐度以及盐度变化对微生物有抑制作用,破坏微生物的代谢功能并降低生物降解能力,导致废水有机物去除率和脱氮效率明显降低,微生物絮凝效果变差。通过工艺技术改造,降低废水全盐量和排放量,稳定排水水质,对提高废水生物处理效果将起到促进作用。

The high salinity and salinity changes of wastewater can inhibit microbial activity,destroy the metabolic functions of microorganisms and reduce the ability of biodegradation. The organic matter removal rate and denitrification efficiency of wastewater will be significantly decreased,and the effect of microbial flocculation will be worse. Through technological transformation,it can reduce the total salt content and discharge of wastewater and stabilize the water quality of drainage,which will promote the improvement of the biological treatment effect of wastewater.
