摘　　要：为了解决黑臭水体中磷元素祛除流程繁琐、效率低、成本高的不足,提出了一种新的黑臭水体中高效脱磷工艺。以改性镁铝水滑石为核心,对不同水环境因素下改性铝镁水滑石的吸附效果进行了研究。结果表明,污水中磷浓度越高水滑石的吸附效果越好,新的脱硫工艺对污水中磷的祛除率达到了92.58%,脱磷成本能够降低7.4%。对优化污水除硫工艺,降低污水净化成本具有十分重要的意义。In order to address the shortcomings of cumbersome,low efficiency,and high cost in phosphorus removal process in black and odorous water bodies,a new high-efficiency phosphorus removal process in black and odorous water bodies has been proposed.The adsorption effect of modified magnesium aluminum hydrotalcite under different water environmental factors was studied,with modified magnesium aluminum hydrotalcite as the core.The results showed that the higher the phosphorus concentration in wastewater,the better the adsorption effect of hydrotalcite.The new desulfurization process achieved a phosphorus removal rate of 92.58%in wastewater,and the dephosphorization cost could be reduced by 7.4%.It is of great significance to optimize the sulfur removal process of sewage and reduce the cost of sewage purification.
