Research on treatment of domestic wastewater by integral OCO process

It has reported an improved domestic wastewater treatment process, integral OCO process, which comprised bio-film and activated sludge process. Compared with the traditional one, it possesses the following advantages. First, it combines the bio-chemical reactor with the secondary clarifier, which saves floor area and capital expenditure. Second, self-driven reflux of sludge has been carried out, so expenditure for the facilities purchase, operation and maintenance can be cut down. Third , it makes full use of the advantages of both bio-film and activated sludge process. The experimental results indicate that the process is effective for domestic wastewater treatment.
