Description
Technical field
The utility model relates to field of sewage treatment equipment, specifically a kind of multi-layer type domestic sewage processing system.
Background technology
Current biological treatment is the main method of sewage disposal, can be divided into activated sludge process and biomembrance process.Activated sludge process is due to technology maturation, and equipment is reliable, is able to widespread use, but there is the problem of fluctuation of service in middle-size and small-size sewage disposal, easily occur sludge bulking, and energy consumption is higher at large-scale wastewater treatment plant.The principal mode of biomembrance process has: biological filter, blodisc and biological contact oxidation process etc., be used for middle-size and small-size sewage disposal.Blodisc is due to features such as processing efficiency are high, maintenance management convenient, working cost is low, oneself is used widely in the process of middle-size and small-size sanitary sewage and trade effluent, and achieve good effect, but current blodisc is owing to being present among sewage for a long time, be easy to cause rotating disk drive-motor to damage, rotating shaft is worn and torn, need often to change, therefore the increase of cost is brought, simultaneously also unusual inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of multi-layer type domestic sewage processing system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of multi-layer type domestic sewage processing system, comprise oxidation zone, denitrification zone, nitrification zone, dirt disengaging zone and sewage discharge district, the top of described oxidation zone is provided with sewage inlet, and the below of sewage inlet is provided with the movable grid bucket arranged, rubbish larger in sewage is stopped by grid bucket, simultaneously when the rubbish in grid bucket is too much, also grid bucket can be taken out cleaning, therefore convenience very, the bottom of described oxidation zone connects ozone generator by pipeline, is oxidized sewage by ozone; Filtering net is provided with between described oxidation zone and denitrification zone, described denitrification zone connects nitrification zone by water pump A, and be provided with aeration plate in nitrification zone, described aeration plate connects air pump by airway, in nitrification zone, inject air by air pump, thus carry out Air Exposure; Blodisc is provided with in described nitrification zone, the drive-motor and blodisc is in transmission connection, the outside of described drive-motor is provided with that engineering plastics are made and airtight outer cover, by outer cover, drive-motor and rotating shaft and sewage thereof is isolated, prevents the sand in sewage from entering in rotating shaft and drive-motor.
As further program of the utility model: described nitrification zone connects dirt disengaging zone by water pump B, and is provided with central tube in dirt disengaging zone.
As the utility model further scheme: described dirt disengaging zone connects sewage discharge district, and sewage discharge district is provided with sewage draining exit.
Compared with prior art, the beneficial effects of the utility model are: the utility model is relative to existing product facility, its packaged type grid bucket can be more convenient the larger rubbish of process, also entirety can shift out cleaning simultaneously, be provided with that engineering plastics are made and airtight outer cover in the outside of the drive-motor of blodisc simultaneously, by outer cover, drive-motor and rotating shaft and sewage thereof are isolated, prevent the sand in sewage from entering in rotating shaft and drive-motor, therefore the work-ing life of equipment is extended, decrease maintenance number of times, reduce cost payout.
