Abstract

The utility model provides a domestic sewage treatment system for solving the domestic sewage treatment problem, which mainly structurally comprises a sewage pump, a sedimentation tank, a primary filtering tank, a high pressure pump, an ultrafiltration membrane filtering tank and an ultraviolet sterilization tank. The sewage pump is connected with the primary filtering tank, the primary filtering tank is connected with the ultrafiltration membrane filtering tank via the high pressure pump, and the ultrafiltration membrane filtering tank is connected with the ultraviolet sterilization tank.

Description

Domestic sewage processing system

Technical field

The utility model relates to a kind of domestic sewage processing system, belongs to water treatment field.

Background technology

Present most of sanitary sewage all is unprocessed direct discharging, both pollutes to environment, again waste water resource.Chinese patent: disclose the dense water depth treatment system of a kind of middle-end reuse water one-level No. 200920204474.2, this system's primary structure comprises raw water pump, first-stage reverse osmosis film, two-pass reverse osmosis film and high-pressure pump.Raw water pump connects by first high-pressure pump and first-stage reverse osmosis symphysis, and the first-stage reverse osmosis film connects by second high-pressure pump and two-pass reverse osmosis symphysis.Though this system can better must dispose of sewage, and obtains industrial reuse water, applicable surface is narrow, can't the fine sewage that must handle other field, and for example sanitary sewage, and this system adopts twice pressurization, the energy consumption height.

The utility model content

The utility model provides a kind of domestic sewage processing system for solving the sanitary sewage disposal problem.

The technical solution of the utility model is: a kind of domestic sewage processing system comprises sump pump, settling tank, primary filter pond, high-pressure pump, ultrafiltration membrance filter pond, ultra-violet sterilization pond.Sump pump links to each other with the primary filter pond, and the primary filter pond links to each other with the ultrafiltration membrance filter pond by high-pressure pump, and the ultrafiltration membrance filter pond links to each other with the ultra-violet sterilization pond.

Be connected with reuse tank as preferred ultra-violet sterilization pond.

In sum, the utlity model has following advantage:

The utility model adopts first post precipitation to filter germ-resistant again processing route, can effectively must alleviate the operating pressure in ultrafiltration membrance filter pond, and handles and thoroughly can directly use as domestic water.And native system only adopts once pressurization, has reduced energy consumption.

Description of drawings

Fig. 1 is a system chart of the present utility model.

Embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model provides a kind of domestic sewage processing system, and this system mainly comprises sump pump, settling tank, primary filter pond, high-pressure pump, ultrafiltration membrance filter pond, ultra-violet sterilization pond, reuse tank.Sump pump links to each other with the primary filter pond, and the primary filter pond links to each other with the ultrafiltration membrance filter pond by high-pressure pump, and the ultrafiltration membrance filter pond links to each other with the ultra-violet sterilization pond, and the ultra-violet sterilization pond links to each other with reuse tank.

Principle of work of the present utility model is: sewage is earlier through the settling tank precipitation, removes wherein density greater than water and water-fast impurity.The water of discharging afterwards flows into the primary filter pond, through strainer filtering wherein density smaller or equal to water and water-fast impurity.Through the high-pressure pump pressurization, reach the required seepage water pressure of ultra-filtration membrane then, flow into the ultrafiltration membrance filter pond.Impurity soluble in water can be removed in the ultrafiltration membrance filter pond, flows into the ultra-violet sterilization pond from the water of wherein discharging, and through ultra-violet sterilization, can obtain comparatively clean water source.It is stand-by that the water of discharging from the ultra-violet sterilization pond at last flows into reuse tank.

It is more reasonable that the utility model is handled the arrangement of route route, most of impurity and microorganism in the energy treating water.And owing to only adopted once pressurization, energy consumption is low.Realized the processing reuse of sanitary sewage.

Claims

1. domestic sewage processing system, it is characterized in that: comprise sump pump, settling tank, primary filter pond, high-pressure pump, ultrafiltration membrance filter pond, ultra-violet sterilization pond, described sump pump links to each other with the primary filter pond, described primary filter pond links to each other with the ultrafiltration membrance filter pond by high-pressure pump, and described ultrafiltration membrance filter pond links to each other with the ultra-violet sterilization pond.

2. a kind of domestic sewage processing system according to claim 1 is characterized in that: described ultra-violet sterilization pond also is connected with reuse tank.
