Abstract

The utility model relates to a device for recycling domestic sewage. The device is characterized by comprising a regulating pond (1), an ozone generation device (7) and an air blower (8), wherein the water inlet end of the regulating pond (1) is provided with a grid (2), and the domestic sewage to be treated flows into the regulating pond (1) through the grid (2); the regulating pond (1) is sequentially connected with an SBR (Sequencing Batch Reactor) reaction pond (3), an MBR (Membrane Biological Reactor) reaction pond (4) and a recycling water pond (5) through pipes; the MBR reaction pond (4) returns sludge into the SBR reaction pond (3) through a sludge pump (6); the ozone generation device (7) blows ozone into the water body of the MBR reaction pond (4); the air blower (8) blows air into the water body of the MBR reaction pond (4). The device disclosed by the utility model has the advantages of stable water quality and high water quality of treated effluent water, compact structure and small occupied area and can completely meet the requirement for usage.

Description

One way of life wastewater reusing device
Technical field
The utility model belongs to sewage reuse field, is specifically related to one way of life wastewater reusing device.
Background technology
City domestic sewage finally enters municipal sewage plant and processes, for saving water source, in prior art, some reclamation sets, by being used as greening, landscape water after sanitary sewage disposal and flushing the toilet etc., have been saved water resources greatly, can also reduce the long processing load of municipal sewage treatment.
But the processing water outlet of existing sewage reuse device often can not be completely up to standard, and stable effluent quality neither be fine, the aspects such as landscape water of therefore having relatively high expectations at water, can't rely on the processing water outlet of reclamation set completely.
Utility model content
The utility model provides one way of life wastewater reusing device, processes stable effluent quality, and water quality is higher, can meet service requirements completely, and compact construction, takes up an area few.
For achieving the above object, the technical solution adopted in the utility model is: one way of life wastewater reusing device, comprise equalizing tank, the feed-water end of this equalizing tank is provided with a grid, described pending sanitary sewage flows in equalizing tank through grid, and described equalizing tank is managed successively and connected sbr reactor pond, MBR reaction tank and reuse pool again;
Described MBR reaction tank through a sludge pump by sludge reflux to sbr reactor pond;
One ozone generating-device blasts ozone in the water body of MBR reaction tank;
One gas blower blasts air in the water body of MBR reaction tank.
Further, the film water outlet of described MBR reaction tank is in reuse pool described in a suction pump suction.
Further, in described equalizing tank, be provided with a submersible pump, for by equalizing tank water suction sbr reactor pond.
Principle of work of the present utility model: sanitary sewage is removed macrobead pollution substance through grid, enters the equalizing tank regulating water quality water yield, and equalizing tank water outlet flows into sbr reactor pond.SBR is a kind of high-effective microorganism treatment technology, it is intermittent cycle activated sludge process, in sbr reactor pond, microbial population experiences successively anoxic, anaerobism, aerobic stage on space-time, not only can remove organic pollutant, simultaneously can also intensified denitrification and dephosphorization, also there is good capacity of resisting impact load.The water outlet of sbr reactor pond flows into MBR reaction tank, and MBR technology claims again membrane bioreactor, is a kind of new type water treatment technology being combined with biological processing unit by film separation unit.MBR technology effluent quality high-quality stable, excess sludge production is few, and floor space is little, occasion is not set and limits, and can remove ammonia nitrogen and hardly degraded organic substance, and convenient operation and management is easy to realize automatic control.After SBR technology is combined with MBR technology, safe and reliable, be difficult for causing secondary pollution, the clearance of the pollutents such as organism, ammonia nitrogen, bacterium and virus is high, and can realize automatization and control, and improves the automatization level of sewage disposal.In MBR reaction tank, be also provided with ozone generating-device, ozone can be strengthened except degerming and virus, guarantees that effluent quality is up to standard, and in addition, ozone equipment is integrated in MBR reaction tank, take up space less, and ozone loss is few, can improve treatment effect.
The beneficial effects of the utility model: process stable effluent quality, water quality is higher, can meet service requirements completely, and compact construction, take up an area few.
