Abstract
The utility model discloses a reverse-flow type domestic sewage treatment device. The reverse-flow type domestic sewage treatment device comprises a water filter, a membrane system, a far-ultraviolet light reactor, a SBR (Selective Beacon Radar) reactor, a separator, a first finished product storage tank, a second finished product storage tank and a high-pressure pump, wherein the water filter is connected to an inlet end of the membrane system through a pipeline, the high-pressure pump is arranged on the pipeline, an outlet end of the membrane system is connected to the far-ultraviolet light reactor which is connected to the SBR reactor, the upper end of the separator is connected to the SBR reactor, and the side surface and the bottom of the separator are respectively connected to the first finished product storage tank and the second finished product storage tank. Compared with the prior art, the reverse-flow type domestic sewage treatment device disclosed by the utility model has the advantages that treated sewage is recycled, so that the discharge amount of sewage can be reduced so as to protect environments, and as the components and the temperature of the treated sewage are very close to the components and the temperature of underground water, the treated sewage can mix with the underground water very well, so that formation swelling is effectively prevented, the ground temperature is effectively prevented from dropping excessively, and the environments are protected well.
Description
Technical field
The utility model relates to a kind of waste disposal plant, specifically a kind of sewage treatment unit of the return-flow type for the treatment of sanitary sewage.
Background technology
In recent years, country progressively strengthens the water-saving and emission-reducing dynamics, sewage drainage standard further improves, contain more leftovers, leftovers and greasy dirt in people's sanitary sewage, they float on the water surface or submerged in the water, affect the foster exchange of air and water termination, and the greasy dirt be dispersed in water can be decomposed by microbiological oxidation, Gu oils not only reduces the rate of exchange of oxygen but also can consume the dissolved oxygen in water, makes water quality deterioration.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, and a kind of return-flow type sewage treatment unit is provided.
Technical scheme: in order to realize above purpose, return-flow type sewage treatment unit described in the utility model, it comprises filter, the film system, the extreme ultraviolet light reactor, the sbr reactor device, separating machine, the first finished product basin, the second finished product basin and high-pressure pump, described filter is connected with described film system upstream end by pipeline, and pipeline is provided with high-pressure pump, the exit end of described film system is connected with the extreme ultraviolet light reactor, described extreme ultraviolet light reactor is connected with described sbr reactor device, described separating machine upper end connects the sbr reactor device, its side is connected respectively the first finished product basin and the second finished product basin with bottom.
Be provided with filtering net in described filter.
Described sbr reactor device is provided with two thief holes, small-sized air compressor and dissolved oxygen meters, described two thief holes are located at respectively bottom and the middle part of sbr reactor device, described small-sized air compressor is located at the bottom of sbr reactor device, described dissolved oxygen meter be located at the sbr reactor device above.
Beneficial effect: return-flow type sewage treatment unit described in the utility model, have the following advantages: filtering net is installed in filter, solid matter insoluble in sewage first can be filtered out, then allow sewage enter in the film system, by ultra-filtration membrane, greasy dirt is processed for the first time, adopt extreme ultraviolet light oxidation-SBR technique to be processed sewage, take full advantage of extreme ultraviolet light to the COD in sewage, BOD and greasy dirt are effectively removed, by processed sewage, re-injection not only can reduce quantity of wastewater effluent with protection of the environment and also because of its component and temperature and underground water very approaching, can mix with underground water well and effectively prevent that stratum from expanding and ground temperature decline is too much, environment is played to good protection.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
