Plant tar and can be deposited on surrounding and the boiler air duct inwall of boiler furnace, have a strong impact on production
The normal usage energy of boiler and service life.Relevant governmental gives up for solving residue still later
The pollution treatment problem of liquid have employed again centralized burning process, is given up by the residue of each manufacturing enterprise
Liquid concentration is transported to solidification disposal of waste center and burns.Solve partial contamination although it is so
Problem, but the process burned also is to increase the process of carbon emission, has also burnt residue simultaneously
The resource of recoverable in waste liquid: as dimethylformamide (be called for short DMF) so and
The theory of the energy-saving and emission-reduction that the whole world is advocated is the most opposed, and the treating capacity of incineration disposal method
It is limited for postscript, substantial amounts of residue waste liquid or pile up like a mountain, burning disposal cost in addition
The highest, the burden of manufacturing enterprise to be laid particular stress on, enterprise's existence manages to arrange steathily the most phenomenon.Burn
Produced substantial amounts of heat energy during burning also could not utilize, the most also can be produced secondary pollution.
