摘要
通过对集成式污水处理装置工艺和运行参数进行优化,选择水力停留时间为32 h、回流比为100%、好氧区DO 2 mg/L为最佳运行工况。并在此基础上,研制出一体化处理设施——净化槽,在北京市大兴区庞各庄镇梨花村对其进行了示范应用,结果表明净化槽具有一定的耐冲击负荷的能力,出水水质稳定,对于推动北京平原地区农村生活污水达标排放具有重要意义。
Through optimization of operating parametersand the processof integrated sewage treatment plant,the best operating conditions are HRT 32 h,reflux ratio 100%,aerobic zone DO 2 mg / L. The studydeveloped the integrated treatment facilities-purification tank on the basis. The technology is applied in the village Panggezhuang Town of Daxing District in Beijing. The results showed that the purification tank has a capacity of some of the resistance to shock loading. The water quality is stable. It has great significance topromote rural sewage discharge standards of Beijing plain area.
