Further, increased aeration tank between described acidication equalizing tank and settling tank, and described aeration tank is provided with underwater aeration machine.
Further, described cascade filtration pond and reuse tank have been set up middle reuse water tank, and described middle reuse water tank is connected with backwashing pump.
Further, the sterilizing agent of described sterilization pool preferably adopts ozone strong oxidizing agent as sterilizing agent, because ozone strong oxidizing agent can not cause damage or destroy people, animal and environment, thereby has improved practicality and the safe reliability of system.
In the utility model, above-mentioned sterilizing agent is not limited only to use ozone strong oxidizing agent as sterilizing agent, also can select according to practical situation.
Further, for improving filtration efficiency and the precision of sewage disposal, employing hollow-fibre membrane is also set in film processing system described in the utility model, thereby has effectively improved efficiency and the precision of sewage water filtration.
In film processing system during the utility model is above-mentioned, preferably adopt hollow-fibre membrane, but be not limited only to this, also can please select by money according to reality.
Further, be the water quality that raising system is disposed of sewage, described cascade filtration pond is provided with charcoal absorption film, and then has realized the object that improves effluent quality.
Cascade filtration pond during the utility model is above-mentioned preferably adopts charcoal absorption film, but is not limited only to this, also can please select by money according to reality.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model, by adopting cascade filtration film processing system, makes to be obviously better than through the middle water effluent quality of the utility model processing the effluent quality of traditional activated sludge process.
(2) the utility model also has advantages of that floor space is little, saves more than 50%, and then reduced investment running cost than the floor space of traditional activated sludge process.
(3) the utility model operation is simple, substantially can realize unattended duty, is not subject to the variation of temperature, the water yield, and compact equipment, can move continuously according to practical situation easy care simultaneously.
