 Second, the construction method 

 1, the use of a cesspool above the entrance of the hole used for the construction, equipment, personnel, and sludge for this discrepancy. 

 , Cut off water to the water to solve the problem of temporary drainage during construction. 

 , Sewage pool area is large, year-round closure of the accumulation of sewage sludge fermentation tanks will have a very strong toxic and harmful gases. From safety considerations, we pool operation, located in the site safety officer is responsible for safe working full-time to ensure foolproof.
