| 摘 要： | 针对在活性污泥法工艺中究竟应该取消还是保留初沉池这一争论.通过静态和动态沉淀模拟试验,研究初沉池的水力停留时间与初沉池沉降效应的关系,以确定比较合适的初沉池水力停留时间.研究表明,初沉池沉淀时间控制在0.5~1.0h之内应该是适当的,一方面可维持初沉池的本来功能,同时也缓解脱氮除磷中存在的碳源矛盾;另一方面可降低工程基建投资.

| Abstract: | Whether the primary settling tank should be canceled or not in the activated sludge method is a controversial question. In order to probe the relation between the HRT and settling effect of the primary settling tank and to confirm the suitable HRT, both static test and dynamic test are conducted in this research. The research shows that the HRT of primary settling tank can be shortened to 0.5-1.0 hour. In this case, the primary settling tank can keep its original function, and at the same time it can also alleviate the contradiction of carbon sources between the removal of nitrogen and phosphorus; on the other hand, it can reduce the capital expenditure of the project. |
