The interception trunk and forward year after the completion of sewage treatment plants can effectively reduce the downstream sewage: CODcr 2790 吨, BOD5 5150 吨, SS 2790 吨, TN 429 吨, TP 42.9 tons.

This sewage interception mains and forwards sewage treatment plant completed each year after can effectively reduce the downstream CODcr sewage: 5 5150 2790 tons, BOD SS 2790 tons, 429 tons, TN TP 42.9 tons and tons.

After this truncation dirty collecting main and the forward sewage treatment plant completes every year to be possible to reduce effectively to the downstream emissions sewage: CODcr 2790 tons, BOD5 5150 tons, SS 2790 tons, TN 429 tons, TP 42.9 tons.

This sewage intercepting main pipe and long-term sewage treatment plants after the completion of each year will effectively reduce the dumping of sewage into the downstream: CODcr 2,790 tonnes, BOD5 5,150 tonnes, SS 2,790 tonnes, TN 429 tons, TP 42.9 tons.

The interception trunk and forward year after the completion of sewage treatment plants can effectively reduce the downstream sewage: CODcr 2790 吨, BOD5 5150 吨, SS 2790 吨, TN 429 吨, TP 42.9 tons.
