地沟式土地处理技术脱磷效果及影响因素研究

Dephosphorization efficiency with under ground-ditch-pattern soil treament and its affecting affecting factors

地沟式污水土地处理技术是一项设备简单、操作管理方便、能耗低、投资少 ,以及较高的净化效率 ,并具有广阔发展和应用前景的实用技术。在对贵州省环科院内地沟式土地处理中试实验进行系统分析的过程中 ,得出该系统具有较高的磷去除率 ,并且不受时间限制 (冬季仍能正常运行 ) ,讨论和分析了BOD5 /TP和CODcr/TP值对TP去除效率的影响以及其最佳去除条件 ,水力负荷的不同对TP去除效率的影响。

Because of its low cost, easy operation and management, the technique of under g round-ditch-pattern soil treatment is practical and has more chances for devel opment. In this paper experimental results show that this system has high remova l rate of TP and is unlimited for seasons. This paper also studies on the differ ent affecting factors for the removal rate of TP.
