摘要
根据水质指标评价法对两污水厂进水进行可生化性分析,探讨进水可生化性对污水厂处理效果的影响。对2座污水处理厂进、出水中CODCr、BOD5、TN、TP进行监测,从m(BOD5)/m(CODCr)和m(TP)/m(CODCr)比值判断进水可生化性对出水中BOD5、TN、TP去除效果的影响。试验结果表明:通过对进水可生化性的分析,可以判断可溶性有机物的去除效果,但是对于TN、TP的去除效果还不足以进行可靠的判断。
The biodegradability of the influent water in two wastewater treatment plants was analyzed based on water quality index evaluation method, and the influence of biodegradability on wastewater treatment effect was discussed at the same time. The mass concentrations of CODcr, BODs, TN and TP in the influent and effluent water of the said two plants were monitored, and then, the effect of influent biodegradability on BODs, TN and TP removal was estimated according to the ratios of m（BODs）/m（CODcr） and m（TP）/m（CODcr）. The results of the test showed that： through the analysis of the influent biodegradability, the removal efficiency of soluble organic matters could be estimated; however, the estimations on the removal efficiency of TN and TP were not accurate enough.
