Embodiment Construction
[0006] The present invention will be further described in detail below in conjunction with the flowchart.
[0007] Each CASS reaction pool is composed of three parts, namely the bacterial group selection area, the facultative oxygen area and the main reaction area. The flora selection area is set at the front of the CASS pool, which is a small volume pool (about 10% of the total volume of the reactor), and most of the selection area works under anaerobic or facultative oxygen conditions.
[0008] Use the sludge return pump to pump the sludge from the main reaction area and mix it with the new sewage, which not only can
[0009] The activated sludge can be quickly adsorbed, and it can also speed up the removal of dissolved substances, and it can also remove refractory substances
[0010] Play a better role in the replacement, of course, can also effectively release the phosphorus in the sludge under anaerobic conditions.
[0011] Setting the bacterial group selection area bef...
