Abstract

The utility model relates to an integration treatment of living sewage, which integrates the functions of an aeration tank, second sedimentation tank and mud return system into one tank. The tank body is divided into one subsiding region and two aeration regions by separation plates; the bottom of the settlement region and the aeration regions are communicated; the outgoing water of aeration regions from the bottom of the separation plate goes to settlement region, then overflows from the settlement region after natural settlement process; the overflowed water is the standard yield water. The device has the advantages of low investment and operation cost, small occupied area and simple operation.

Description

The sanitary sewage integrated treatment unit

Technical field

The utility model relates to a kind of sewage treatment unit, belongs to technical field of sewage.

Background technology

At present, known Sewage treatment systems is to be formed by connecting with pipeline and relevant device by several parts such as primary sedimentation pond, aeration tank, secondary sedimentation basins, mud return-flow system and sludge treating systems.Sewage enters primary sedimentation pond post precipitation supernatant liquor and enters aeration tank aeration processing, mud enters sludge treating system, the sewage of handling by aeration enters the superfluous shallow lake of secondary sedimentation basins, supernatant liquor in the secondary sedimentation basins enters next process sterilization back reuse or effluxes, secondary sedimentation basins mud has part to return the aeration tank by the mud return-flow system, and another part enters sludge treating system.It is too many that this Sewage treatment systems drops into facility, causes the cost of investment height, and floor space is big, running cost height, complicated operation.

Summary of the invention

In order to restrain the deficiency of the above-mentioned several respects of the existing Sewage treatment systems of eye, the utility model provides a kind of can not only accomplish to drop into that facility is few, cost of investment is low, floor space is little, running cost is low, simple to operate, and can make the water treatment index reach the sanitary sewage integrated treatment unit of discharging standards.

The scheme that the utility model solves its technical problem is: aeration tank, secondary sedimentation basins, several parts of mud return-flow system are arranged in the body of same pond, with dividing plate the pond body is divided into negative area and aeration zone three parts, negative area and bottom, aeration zone communicate, the aeration zone water outlet enters the negative area from the lower partition, then in the negative area natural subsidence, overflow from top, negative area at last, the water that overflows is exactly treat effluent up to standard.Waste disposal plant negative area bottom design becomes 55-65 degree angle, to realize the mud natural back flow, does not need to increase power.

The utility model has the advantages that, can make waste disposal plant simple in structure when reaching discharging standards disposing of sewage, reduce processing links, it be few to realize dropping into facility, and cost of investment is low, and floor space is little, and running cost is low, and is simple to operate.

Description of drawings

Below in conjunction with accompanying drawing the utility model embodiment is described further.

Fig. 1 is an embodiment schematic top plan view of the present utility model;

Fig. 2 is the I-I sectional view of Fig. 1.

1. pond bodies among the figure, 2. clear water spilling water groove, 3. dividing plate, 4. clear water effluent trough, 5. blast pipe, 6. sewage draining exit, 7. sewage water inlet pipe, 8. aeration zone, 9. negative area, 10. kerve.Clear water spilling water groove (2) edge in the body of pond, to the height of top, pond horizontal plane be 200 millimeter.Dividing plate is divided into aeration zone and negative area to whole pond.Fig. 1 is the parallel connection of two monomer devices, and each monomer device can use separately, also can the use in parallel of a plurality of monomer devices.

Embodiment

In the embodiment shown in fig. 1, pond body (1), clear water spilling water groove (2), dividing plate (3), clear water effluent trough (4) are done all to form an integral body with concrete casting in the process in the pond system, also available steel plate is welded (if pond body (1), clear water spilling water groove (2), dividing plate (3), clear water effluent trough (4) are made of unlike material, can connect by built-in fitting).Sewage water inlet pipe (7) can be arranged on optional position, top, aeration zone.

In embodiment illustrated in fig. 2, blast pipe (5) connects aerating system.Sewage draining exit (6) is the unnecessary mud of removal system regularly.The pond body conjunction plane of pond body (1) both sides and kerve (10) is designed to the scarp at 55-65 angle, and the mud natural back flow that helps negative area (9) is to the aeration zone (8).Aerating system is installed in the kerve, influences the effect of settling of negative area (9) when preventing aeration.Before sanitary sewage enters integrated treatment unit, at first remove bigger solid impurity in the sewage through the barrier machine, enter water collecting basin again, stablize to keep the integrated apparatus water inlet by the water collecting basin regulating pondage, put into half pond sewage to integrated apparatus then, put into bacterial classification again, and provide pressurized air to begin aeration for the device aerating system, conform with the domestication biological inoculum.Adopt during the domesticated strain and be interrupted water inlet, after the settling tank water outlet reaches discharging standards, adopt water inlet continuously again, and increase the water yield gradually, till reaching the designing treatment amount.Sewage adds from top, aeration zone, in the aeration zone with biological inoculum fully contact produce aerobic reaction after, enter the negative area by the lower partition again, in the uphill process of negative area, play sedimentation and anaerobic reaction double effects simultaneously, water quality further is purified.In the device operational process, can not interrupt aeration,, must stop into water in case have a power failure, so as not to cause bacterial classification to run off and sewage in line.

Claims

1, a kind of sanitary sewage integrated treatment unit, form by major portions such as pond body, dividing plate, clear water spilling water groove, clear water effluent trough, blast pipe, sewage draining exit, sewage water inlet pipes, it is characterized in that aeration tank, secondary sedimentation basins, mud return-flow system all are arranged in the body of same pond.

According to right 1 described sanitary sewage integrated treatment unit, it is characterized in that 2, dividing plate is divided into aeration zone and negative area three parts to whole pond, the pond body conjunction plane of body two sides, pond and kerve is designed to the scarp at 55-65 angle.

3, according to right 1 or 2 described sanitary sewage integrated treatment units, it is characterized in that each monomer device can use separately, also can the use in parallel of a plurality of monomer devices.
