巢湖原水生物接触氧化预处理的研究

STUDY ON RAW WATER PRETREATMENT BY BIOLOGICAL CONTACT-OXIDATION PROCESS OF CHAOHU LAKE

本研究以巢湖水直接进行生物陶粒接触氧化预处理试验,试验结果表明生物接触氧化预处理对巢湖水源中的COD_(Mn)、NH_3-N、NO_2^--N、色度、臭味等具有较好的去除效果,从而减轻了常规净水处理工艺的负荷,节约了混凝剂。

'Best results to remove the COD, NH3 -N, NO2 - N, colourity and smell are obtained in the experiment of direct pre-treatment of raw water abstracted from Chaohu Lake in Anhui Province by the ceramsite contacted biological oxidation process (CCBO) and so the loading of conventional water purification process and the consumption of coagulants would be reduced.
