滦河原水水质应急预处理方法研究

Study on emergency pretreatment of raw water quality in Luanhe River

模拟水质恶劣的情况下,滦河原水经于桥水库流至塘沽某水厂的全过程,考察了沿途投加KMnO4复合盐、NaClO溶液和CuSO4溶液3种处理剂以及活性炭吸附剂的预处理效果。结果表明:经过不同的处理剂预处理及活性炭吸附后,原水水质都得到明显改善。其中,KMn O4复合盐和CuSO4溶液的投加效果更为明显,UV254最高去除率达到67. 69%,藻类去除率达到99. 73%,经过预处理后原水已能够满足下游水厂的处理要求。

Simulation of the whole process of Luanhe raw water flowing through the Yuqiao Reservoir to a water treatment plant in Tanggu was carried under the bad water quality. The pretreatment effect was investigated by adding KMn O4 compound salt,NaClO solution and CuSO4 solution as well as activated carbon adsorbent along the passway. The results show that the quality of raw water has been significantly improved after pretreatment with different treatment agents and adsorption with activated carbon. Among them,the effect of KMn O4 compound salt and CuSO4 solution was more obvious,the highest removal rate of UV254 is 67. 69%,algae removal rate is 99. 73%. After pretreatment,the raw water could satisfy the treatment requirements of downstream waterworks.
