The engineering research of City life sewage treatment
The sewage from produces to discharge into the nature once more is an extremely complex process. It has much knowledge from the collection of sewage, the determination of water quality and water volume in dirty waterworks and the way of the treatment craft. The design of the sewage treatment plant is extremely complex. To obtain the method of sewage collection, we have chosen the reasonable way by satisfying all kinds of requirements. Considering all kinds of factors to determine the water volume and water quality in dirty waterworks. Contrasting with the multitude processing methods and combined with the fact in the local place, we obtained the reasonable processing craft (the CASS craft). We have completed the regeneration and reuse the sewage, processing and handling with this craft sludge .The sewage treatment enterprise has already rapidly developed, many new theories and new technologies has appeared and many standards had been promulgated. There is much work to do in order to fatherly develop water enterprise.
Key word: Active sludge method, CASS pond, sludge, reuse
