The annual production of sludge is increasing, 80% of which is not stabilized and harmless, and it is expected to exceed 60 million tons in 2020.

How to treat the huge amount of sludge produced behind the well-functioning urban sewage treatment plants?

"Thirty-one percent of the sludge disposal methods in China are landfills, which have not been stabilized and are likely to cause secondary pollution to the environment. 3.45% of the sludge and waste mixed landfill, the sludge actually belongs to the landfill category; 44.83% of the sludge was used for agriculture. 3.45% of the sludge was incinerated." This set of data released at the first pearl river delta water treatment exchange conference truly reflects the current situation of sludge disposal in China.

The dilemma of sludge treatment and disposal in urban sewage treatment plants in China is that the yield is large, the composition is complex, most of the sludge has not been stabilized, harmless treatment and disposal, easy to cause secondary pollution. However, many people still have insufficient understanding of the harmfulness of sludge, and the current situation of sludge disposal is worrying

Treating water without treating mud is equal to not treating water; Water treatment does not treat mud, pollution transfer.
