Technique of traditional sewage disposal of collect Chinese style gains ground relatively in home, but the issue that is put in expenses of high investment, expensive operation, and the effect is not stable, realize stability to amount to mark to discharge hard. After carrying out new nation to discharge a standard especially, no matter be in,economic cost still is handling effect side, a lot of enterprises are carried out hard or bear to be treated existingly corrupt mode. The reporter learns, one kind come from the United States " technology of A Keman zoology " , in order to invest little, get effective fast advantage help company spans capital and technical doorsill.
The tradition is treated corrupt mode, high yield of big devoted unlikelihood goes out
The expert points out, the liquid waste processing system of average company uses traditional content to change law and biochemical way, cannot undertake complete processing to the industrial waste water that complex, Gao Nong spends part, and the effect is not stable, because this realizes stability hard,amount to mark to discharge. This also is to come to a lot of enterprises for years industrial contaminant discharges gross all the time hard revolutionary the prime cause that drop.
In addition, the enterprise built sewage disposal system to raise taller requirement to capital and technology. If say, the big company with rich actual strength still can increase investment, through using advanced technology, increase early days earth to build the method such as investment to ensure amount to mark, medium and small businesses faces the pressure that invests cost to appear unable to do what one wants very much to do. After carrying out new nation to discharge a standard especially, no matter be in,economic cost still is handling the effect two respects, a lot of medium and small businesses are carried out hard or bear to be treated existingly corrupt mode.
Zoology technology is efficient treat industrial waste water, for the enterprise solution is stranded
Industry of our country spin discharges liquid waste every year many tons 900 million, among them 80 ％ are liquid waste of printing and dyeing. Liquid waste of printing and dyeing still has decolour difficulty, contain machine content concentration advanced characteristic, the Chongzhongzhi in job of the sewage disposal that be regarded is heavy.
Fosan 3 Shui Mou is large printing and dyeing mill, have treating capacity of 40 thousand tons of industrial waste water everyday. System of original sewage disposal is put in the problem with not stable water quality giving water from beginning to end, COD and chroma cannot amount to mark. To solve this one difficult problem, this factory uses technology of A division tendril to undertake transforming to system of original sewage disposal, use plant area pond of oxidation of extensive of tendril of division of A of unused land construction, amid installs A Keman to give birth to voice radical, undertake to the sewage of original system eduction deepness is handled. The system is transformed need not increase specific power consumption newly. Finishing after 16 days, float oxidation pond already achieved very tall processing efficiency. Via detecting, COD cuts down 47.5mg/L from 119.3mg/L, cut down nearly 60% , SS cuts down 155.4mg/L from 677.7mg/L, cut down amount to 77% , chroma criterion from 50 times drop 12 times, water quality giving water promotes apparently, the processing of low cost deepness of liquid waste of printing and dyeing came true in home.
