摘要
根据煤气化废水水质特点,采用石灰法进行预处理,去除废水总硬度和悬浮物,在SBR池前增加好氧生物选择池去除废水总磷,在SBR池增加MBR生物膜反应器,提高出水水质和处理能力,改造后实现达标排放。
Coal gasification wastewater with its special characteristics was pretreated to remove the total hardness and suspended solid by lime stone method. An aerobic biological selection pool was added before SBR pool to remove the total phosphorus,while an MBR biological membrane reactor was installed in SBR pool to enhance the effluent water quality and treatment capacity. The excellent drainage water quality can meet the requirements of environment protection standards.
