斜管井取黄河渗透水供生活饮用的研究

Study on Inclined Tube Well Collecting Percolating Ground Water of Huanghe River for Daily Drinking

目的 探索为黄河沿岸居民提供经济有效的供水方法。方法 打斜管井深入黄河河床以下 30 m处 ,以大功率水泵抽水 ,经加氯消毒后供生活饮用。于丰、枯水期检测斜管井源水水质并同黄河源水比较。结果 丰、枯水期斜管井源水感官性状及化学指标如 :色度 (5度 )、浑浊度 (<3度 )、硫酸盐 (82 .6～ 84.0 mg/ L)、氯化物 (5 8.7～ 5 7.3mg/ L)、氟化物 (0 .44～ 0 .46 mg/ L)、溶解性总固体 (44 7～ 488mg/ L) ,毒理学指标如 :硝酸盐氮 (<0 .2 5 mg/ L) ,细菌学指标如 :细菌总数 (9.6～ 12 .2 CFU/ ml)和大肠菌群 (0 / ml) ,均优于黄河源水。结论 该取水方法工艺简单 ,投资少 ,供水量稳定 ,水质可靠 。

Objective To explore economic and effective water supplying method for residents living along Huanghe River Methods An inclined tube well collecting percolating ground water with powerful pump in the water bearing stratum in the depth of 30 meters below the riverbed of Huanghe River was built After chlorination,the pumped percolating water was supplied to residents for drinking and living The comparison of the sanitary quality between the percolating water collected from inclined tube well and the untreated Huanghe River water was carried out during plenty water period and low water period Results The organoleptic and general chemical indexes such as color(5 TCU),turbidity(3 NTU),sulfate(82 6~84 0 mg/L),chloride(57 3~58 7 mg/L),fluoride(0 44~0 46 mg/L) and total dissolved solids(447~458 mg/L),toxical index such as nitrate(<0 25 mg/L),bacterilogical indexes such as total count of bacteria(9 6~12 2 CFU/ml) and total coliform(0 MPN/ml),were better than those of source water of Huanghe River during plenty water period and low water period Conclusion This water supply system revealed simple technological process, less investment, stable water capacity and reliable water quality,which was worthy to be popularized
