摘要
在小试研究基础上 ,开展了磁种絮凝 高梯度磁分离净化处理城镇污水的扩大连续试验研究。试验结果表明 ,该工艺对去除城镇污水中的磷、重金属有特效 ,并能同时去除其中的CODCr、BOD5、SS ,出水水质达到或接近国家一级排放标准 ,是一种很有发展前途的工艺 ,尤其适用于城市小区、小城镇污水处理厂建设。
The scale-up continuous test of magnetic flocculation and high gradient magnetic separation of municipal sewage was carried out on the basis of lab experiment. The test results have shown that this process have special effect on removal phosphate and heavy metals, and it can also remove COD Cr、BOD 5、SS in municipal sewage, making outflow quality meet or approach the national discharge standards of pullutants for municipal waste water(GB18918-2002). It is a promising technology, especially suitable for community or minor city sewage treatment, enlargement of major city sewage treatment plant and further treatment of outflow from sewage treatment plant.
