Location       ShandongChina

Challenge
The design capacity of the WWTP is 1,200,m3/h，below data shows the influent and effluent parameters of the plan 设计规模为 1,200,m3/h， 污水厂进出水指标如下：

Solution

The post MBBR process, for further degradation of refractory organic matters.

后置 MBBR 工艺，用于难降解有机物的进一步生物处理。

Results

The MBBR Influent COD 80~100mg/l, Effluent COD 50~60mg/l, remove rate is more than 30%. MBBR 进水 COD 值 80~100mg/l，出水 COD 50~60mg/l，去除率高达 30%以上。
