目前,我国医院污水消毒处理效果的监测均采用碘量反滴定法测定余氯;三步多管发酵法测定总大肠菌群。两种检测方法虽然准确可靠,但需要较多的试剂、器材和一定的实验条件。为便于基层医院污水处理站开展医院污水检测工作,保证污水排放质量,我们研制了GW—1型医院污水监测箱。 GW—1型医院污水监测箱,选用DPD余氯目视比色器测定余氯;A-1培养液一步 At present, the monitoring of effluent disinfection treatment in hospitals in our country adopts residual iodine titration to determine residual chlorine. The three-step multi-tube fermentation is used to determine total coliforms. Although the two detection methods are accurate and reliable, they need more reagents, equipment and certain experimental conditions. In order to facilitate the sewage treatment at the grass-roots level hospital sewage treatment station to ensure the quality of sewage discharge, we developed a GW-1 hospital sewage monitoring box. GW-1 hospital sewage monitoring box, use DPD residual chlorine visual colorimetric determination of residual chlorine; A-1 culture medium step
