Description

A sewage separation device after treatment

technical field

The utility model relates to the field of sewage treatment equipment, in particular to a treated sewage separation device.

Background technique

Water pollution refers to the amount of pollutants discharged into a water body that exceeds the content of the substance in the water body and the environmental capacity of the water body, resulting in changes in the physical, chemical, and biological properties of the water body, causing the inherent ecosystem and The function of the water body is destroyed.

In recent years, my country's environmental protection department has done a lot of prevention and control work in water source protection. However, due to the large number of pollution sources and the constraints of existing conditions, the pollution of water sources in the country is still showing a worsening trend. At present, more than 90% of urban waters are seriously polluted, and the water quality of nearly 50% of key cities and towns does not meet the water quality standards for drinking water sources. It can be seen that although my country has done a lot of work in water pollution prevention and control in recent years, the water quality of many rivers and lakes is still gradually deteriorating. Under the premise that my country's fresh water resources are already very scarce, unpolluted fresh water sources are becoming less and less. That is to say, my country's waterworks have to face the use of more polluted raw water whose water quality does not meet the requirements as a source of drinking water.

At present, my country's sewage treatment is facing three most prominent problems: 1) serious shortage of funds; 2) low level of sewage treatment; 3) low treatment efficiency of sewage treatment operating devices.

Contents of the invention

The technical problem solved by the utility model: in order to separate the solid-liquid-gas of the treated sewage, so as to obtain water resources that can be used directly, the utility model provides a treated sewage separation device.

In order to achieve the above object, the utility model adopts the following technical solutions:

A sewage separation device after treatment, including an outlet pipe, an exhaust pipe, a sedimentation area, an annular water collection area, and a three-phase separator, wherein the exhaust pipe, the sedimentation area, and the three-phase separator are connected sequentially from top to bottom; The three-phase separator communicates with the annular water collection area; the outlet pipe is connected to one side of the annular water collection area.

Further, at least one water outlet pipe is provided on the annular water collection area.

Further, the outlet pipes are evenly distributed on the annular water collection area.

Preferably, the three-phase separator is located in the middle of the annular catchment area.

Preferably, the plane of the annular catchment area is higher than the plane of the sedimentation area.

Beneficial effect

Compared with the prior art, the utility model has the following beneficial effects:

(1) The treated sewage separation device described in the utility model separates the treated sewage twice through the sedimentation zone and the three-phase separator, which can improve the water quality;

(2) The treated sewage separation device of the utility model has a simple structure design and is suitable for various cylindrical sewage treatment devices.

Description of drawings

Fig. 1 is a kind of structure schematic diagram of sewage separation device after treatment;

Among them, 1. Outlet pipe; 2. Exhaust pipe; 3. Sedimentation area; 4. Ring catchment area; 5. Three-phase separator.

Detailed ways

Example 1

As shown in Figure 1, a sewage separation device after treatment includes an outlet pipe 1, an exhaust pipe 2, a sedimentation area 3, an annular water collection area 4 and a three-phase separator 5, wherein the exhaust pipe 2, the sedimentation area 3 and The three-phase separator 5 communicates sequentially from top to bottom; the three-phase separator 5 communicates with the annular water collection area 4 ; the outlet pipe 1 is connected to one side of the annular water collection area 4 .

At least one water outlet pipe 1 is provided on the annular water collection area 4 , and the water outlet pipes 1 are evenly distributed on the annular water collection area 4 .

Wherein, the three-phase separator 5 is located in the middle of the annular water collection area 4 .

The plane of the annular catchment area 4 is higher than the plane of the settling area 3 .

The parts and functions thereof of the treated sewage separation device described in the utility model are described in further detail below, specifically as shown in Table 1:

Table 1 Names and uses of each part of the device

The treated sewage is transported to the sedimentation zone 3, where solid-liquid separation is carried out; then solid, liquid and gas are further separated in the three-phase separator 5, and the treated water flows into the ring-shaped catchment zone 4, and It is discharged through the outlet pipe 1; the gas generated during the separation process is collected and discharged through the exhaust pipe 2.
