Wastewater treatment equipment is a kind of efficient sewage treatment equipment.It has the characteristics of high biological density, strong anti-pollution ability, low power consumption, stable operation, easy maintenance and so on.The following Xiaobian introduces the commonly used wastewater treatment equipment treatment technology types.

Wastewater treatment equipment in common use of several treatment technologies

1.MBR process technology

Membrane bioreactor MBR is a high technology developed in the 20th century.It is the combination of membrane separation technology and biological technology of domestic sludge.Solid liquid separation makes effluent quality good, suspended matter and turbidity close to zero, and buried wastewater treatment equipment can be directly reused after treatment.

2.Constructed wetland treatment technology

Rural domestic sewage is treated in septic tanks, and the supernatant enters the inlet well through the collection pipe and flows into the sedimentation tank through the grid. The sedimentation supernatant is pumped into the first-level constructed wetland and then into the second-level constructed wetland.Wastewater from the secondary constructed wetland is returned to the water purification pond, which can be used for greening, irrigation or overflow into a nearby pond.

3.Stable pond treatment technology

In China, especially in the area of water shortage and drought, the stabilization pond is an effective way to utilize wastewater resources.In recent years, it has become a technology that has been promoted in our country.Compared with the traditional secondary biological treatment, algae pond has many unique characteristics.For the relatively rich land resources, the technical level is relatively backward in the rural areas, sewage treatment technology has a higher promotion value.

4.Aerobic biological treatment system

Aerobic biological treatment system is a common treatment technology in rural sewage treatment.Aerobic biological treatment process has its own advantages and disadvantages.Selection should be carefully demonstrated according to the actual situation, with the focus on economic application.
