氧化沟工艺处理火车站废水的运行与调试

Test Run of Oxidation Ditch Technology for Processing Wastewater of Railway Station

以信阳市火车北站污水处理工程为例,介绍了以一体化氧化沟工艺为主的处理工艺及其主要构筑物如:泵井、平流沉砂池、氧化沟以及接触消毒池的结构特点和设计水力负荷条件等。针对火车站废水特有的含油污量高、可生化性差的特点,指出了其运行与调试过程中应注意的问题。

Taking the wastewater treatment project of North Xinyang Railway Station as an example, this paper introduced the oxidation ditch Technology with its construction characteristics and the hydraulic loading of main structures of processing, including the pumping well, horizontal flow type grit chamber, oxidation ditch, contiguous sterilizer and so on. The operating problems in the test run were pointed out for the high oil content and low biodegradability of wastewater.
