Analysis of drinking water quality in Haiyang City

/ Article ID :1001-5914 (2000) 04-0242O1 analysis of drinking water quality in Haiyang City, Juan Lian Jianwei Zhang Dongmei Xin high at the red (Haiyang City, Shandong Province, Health and Epidemic Prevention Station, 2651..) In the Circuit DOI: R123 .1 Document code: C sea water by urban residents mainly from the Health-tim groundwater, surface water. To understand the water quality of domestic water and industrial waste pollution, to grasp the dynamic changes from 1991 to 1998 the city's raw water were Tim bacteria, determination of physical and chemical indicators. Randomly selected 5 representative tapping points and the county a total of 183 samples of resident (left grid rural eastern and western Xin'an Township, north of Xu store. Southern Fengcheng City R /; Tu17 /,[link widoczny dla zalogowanych], 2 / with the Township ,[link widoczny dla zalogowanych], Central Village),[link widoczny dla zalogowanych], testing method then GB575O - 1985 I464 were detected in water samples, the mean value of the data points on behalf of Xuan. Detection of targets and evaluation criteria by GB5749-1985 showed good water quality in eastern and total hardness ranged from 37.5 ~ 95.5mg / L, compounds the boat in the flesh 24.5 ~ 60.5mg / L, nitrate fluoride were below 3.50mg / L, water basically unaffected pollution; west coast. Total water hardness, chloride, fluoride salts stone roller, bacterial indicators were higher than those east,[link widoczny dla zalogowanych], the pit was no significant difference in total study treatment (P> 0.05). The northern mountains to the north store mainly brown, Xu store is the second industrial center of the city, industrial waste pollution is caused by an important reason for commitment. North Wing-quality total hardness, nitrate, fluoride, bacterial indicators were significantly higher than the east, west (P o.05), may be related to organic pollution. City resident unsolicited analysis of wood quality is good. The groundwater quality is poor, and the geological knot skim and accompanied the dye on the surrounding wells,[link widoczny dla zalogowanych], underground surface water bacterial indicators sum significant difference (P <0.05) Fengcheng southern coast, water hardness, fluoride salts partial stone roller high, in part out of the water column of zinc. East, West and central differences (<005). Important reason for water pollution is industrial waste. The results from the analysis of water samples to see: the East and West offer good water quality. Central Fair. Spine stores north, south along the Mei poor water quality, the zinc, arsenic and manganese in the column out, the main factor is the industrial waste pollution, the long-term health hazards of drinking on the great body of water in the nitrite and nitrate on the health of babies harmful. Meanwhile the body of nitrate or nitrite and amines can form N-nitrite based teratogenic carcinogenic properties of sets, which appeal to the whole society, government and environmental protection departments to take effective measures to sound like anti-industrial waste treatment , out of the water purification and disinfection treatment, so as to protect water sources. Improve water quality and ensure public health purposes
