Issue 35/2013 - 100% recovery rate of effluent sludge from long-term refinery production

100% recovery rate of long-term production drainage sludge

Recently, the Changling Refinery "sludge reduction" emission reduction device was fully connected and put into operation
smoothly.
The device transports 1.
5~2 tons of sewage and sludge to the CFB boiler
every day.
They are harmlessly burned after reasonable proportions and mixing with coke and coal, producing high and low pressure steam and electricity, and effectively reducing the discharge of
solid waste from enterprises.

The treatment process of a large amount of oil sludge, dross and activated sludge generated by refining and chemical enterprises is complex, expensive and has certain environmental risks
.
The operation of the device can improve the economic efficiency of the enterprise and is conducive to environmental protection
.

The project started construction in the second half of 2012, the overall process adopts domestic advanced sewage sludge refining technology, the localization rate of equipment reaches 99.
5%, with the characteristics of large processing capacity, simple operation, stable operation, etc.
, and the recovery rate of oil sludge reaches 100%.
