Ability increases to 128,670,000 ton per days from 640,000 ton per days, and National urban wastewater treatment rate is up to 73%.Bioanalysis is carried out at sewage
Reason is that the degraded and removal of pollutant are realized by the vital movement of microorganism, the sterilized heel row of supernatant after processing is up to standard
Put, but 60~80% pollutant formation sludge enters sludge treating system, and from 1978 to 2010, sewage treatment plant produced
Dewatered sludge increase to 6800 ton per days from 150 ton per days, sludge per year over 10% to be incremented by, such as 50,000,000 tons wet muds
(80% is aqueous) needs 40,000 mu of ground daily by 2m height landfills, such as all burnings, and only handling is stacked and discharged with regard to over ten billion
Serious secondary pollution will be produced, from processing of the elimination pollution angle only to sludge progress more thoroughly, the purpose of sewage disposal
Just it is really achieved, otherwise can only regards that will pollute from liquid-phase conversion is solid phase (or semi-solid phase) as.
Therefore it is a critically important environmental protection subject that low cost, which effectively solves its sludge problem,.Sludge emission reduction method has very
It is many, but all there is certain limitation.Only it is that volume is slightly reduced such as sludge dewatering；Sludge is directly utilized, and risk or cost are very
It is high；Ultrasonic grind also is carried out to excess sludge, it is difficult to industrialize and mineral matter is also difficult to decrement；Acid adding alkali chemolysis ore deposit
Material or heating hydrolysis, can increase chemical raw material or cost is significantly increased and biological cycle is influenceed.
