Abstract:
Based on the investigation and field measurement of the water supply, sewage drainage network and the sewage treatment plant, this paper presents the localized data of comprehensive water supply and sewage discharge quota, pollutant discharge coefficient and pollutant discharge quota in Jinan urban district. The results showed that the water demand quota in households was in the range of 65-75 L/(cap·d). The apparent comprehensive water supply quota was in the range of 260-270 L/(cap·d). The apparent comprehensive sewage discharged quota was in the range of 280-330 L/(cap·d). And the apparent discharge coefficient was in the range of 0.95-1.09. The main reason why the discharge coefficient is close to or even greater than 1 may be the existence of self-provided wells that can not be counted, and the groundwater may be infiltrate into the pipe networks. As a result, COD and NH3-N apparent discharge quotas were 85.1 g/(cap·d) and 11.1 g/(cap·d), respectively.
