基于双池人工快渗系统的洗浴废水处理效果研究

Study on the Treatment Effect of Bathing Wastewater based on Double Pool Constructed Rapid Infiltration Systems

洗浴废水的直接排放会导致水体污染和水资源浪费,探寻高效低耗的洗浴废水处理方法,对推进水资源的循环利用具有重要意义。构建双池人工快渗系统处理洗浴废水,考察了其对洗浴废水中表面活性剂(LAS)、COD、NH+4-N、TN、TP的去除效果及机理。结果表明,当进水LAS、COD、NH4^(+)-N、TN、TP浓度分别为4.1~12.6、70.2~182.5、3.5~8.7、5.2~13.3、0.8~3.7 mg/L时,双池人工快渗系统对其平均去除率分别为96.7%、87.5%、96.4%、91.2%、92.8%,出水指标均达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A排放标准。双池人工快渗系统对洗浴废水中LAS、COD、NH4^(+)-N、TN、TP表现出良好的去除效果,可为其再生利用提供一条新途径。

The direct discharge of bathing wastewater will lead to water pollution and waste of water resources.The research It is of great significance for efficient and low-consumption methods for bathing wastewater treatment is of great significance to promoting the recycling of water resources to.explore high-efficient and low-cost methods for bathing wastewater treatment.A double pool constructed rapid infiltration system was constructed to treat bathing wastewater,and its The removal effects and mechanism ofto surfactants such as LAS,COD,NH4^(+)-N,TN and TP fromin bathing wastewater were investigated.The results showed that when the concentrations of LAS,COD,NH4^(+)-N TN and TP in influent wereis 4.1~12.6,70.2~182.5,3.5~8.7,5.2~13.3 and 0.8~3.7 mg/L respectively,the average removal rates of them bythrough using the double pool constructed rapid infiltration system wereis 96.7%,87.5%,96.4%,91.2% and 92.8% respectively,and the pollutant concentrations in effluent wereare all up to first level A standard according to the discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002).The double pool constructed rapid infiltration system showshad a good removal effect on LAS,COD,NH4^(+)-N,TN and TP in bathing wastewater,which can provide a new way for its regeneration and utilizationrecycling.
