目前处理含油污水主要应用核桃壳、石英砂磁铁矿这两种过滤层的滤罐,由于这两种滤罐均需定期停止过滤进行滤罐反冲洗,由于反冲洗完成至滤料重新稳定着床过程中滤罐过滤性能下降,对水质造成影响,同时未用低压稳流技术改造过的滤罐还存在反冲洗过程中跑滤料和憋压的问题。针对现有滤罐反冲洗过程中存在的问题,本文就连续砂滤技术处理含油污水技术进行研究,为污水过滤探讨一种新技术。 At present, the main application of oily wastewater treatment walnut shell, quartz sand magnetite these two filter layer cans, as both cans are regularly filtered to stop the canister backwash, as the backwash to filter to stabilize Bed filter performance during the decline, affecting the water quality, while not using low-pressure steady flow technology has also been able to transform the filter backwash process in the filter media and hold back pressure problems. In view of the existing problems in the backwashing of the canister, this paper studies the continuous sand filtration technology to treat the oily wastewater, and discusses a new technology for wastewater filtration.
