摘要
利用生物工程技术筛选、驯化出能够去除水中微污染有机物的工程菌 ,并以颗粒活性炭为载体采用物理吸附法将其人工固定化 ,然后用于微污染水的处理。通过对高锰酸盐指数的连续测定 ,试验结果表明 :工程菌人工固定化形成的生物活性炭对微污染水中有机物去除率较高 ,并且稳定 ,高锰酸盐指数去除率平均 4 0 % ;出水高锰酸盐指数 <2 5mg L ,浊度 <1 0NTU ,细菌总数 <10 0cfu mL ,总大肠菌群未检出。
The technology of engineering bacteria was used to select and domesticate engineering bacteria which can remove the organic micr-pollutants in slightly polluted water.Then the eng-bacteria were immobilized by physico-adsorption using the carrier of granule active carbon to treat the slightly polluted water.The index of permangante was tested continuously.The result of the test was that the bio-activated carbon had the characteristic of high removal rate and stabilizaiton,and whose average removal rate of the index of permanganate was 40%,with the index of permanganate <2 5 mg/L,turbidity<1 0 NTU,the amount of bacteria<100(cfu/mL);and total coliform group is not found in the final effluent.Therefore,the technology of immobilized bio-activated carbon has the characteristic of high efficiency,stabilization and security in treating micro-polluted water or advanced treatment of drinking water.
