基于小城镇污水处理实验研究

Experimental Study on Wastewater Treatment in Small Towns

基于小城镇污水处理实验研究,以水厂进水为实验原水,培养生物膜至固着状态,研究对进水浓度下出水指标变化情况,计算各指标去除率。常温状态下(20℃以下)检测记录运行中各项污染指标,对比原指标均有较大的提升,实验工艺抵抗冲击能力强,处吨水费用0. 404元,满足《城镇污水处理厂污染物排放标准》一级A标准要求,为提标改造提供理论技术支撑。

Through experimental study on wastewater treatment in small towns,taking the water from the water plant as the experimental raw water,the cultivation of biofilm to the solid state was conducted to study the change of the effluent index under the water concentration and calculate the removal rate of each index.Under room temperature(20℃)in the operation of the inspection record,the pollution indexes,compared with the original indexes,had large improvement,satisfied the requirement of level of A standard(Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant).The experimental process had strong anti-impact ability,various water outlet indexes were improved,and the processing cost was 0.404 RMB per ton of water,which provided theoretical and technical support for the improvement of the standard.
