Analysis of several common types of sewage settling devices.

        In the common sewage sludge treatment projects, most of them use sedimentation tank for sludge sedimentation and concentration. Compared with the integrated sedimentation device, the investment cost of sedimentation tank is relatively less, but the treatment enterprise is required to have a large enough area for use. However, the design principles of sedimentation tank and sedimentation concentration equipment are basically the same. According to the sedimentation types adopted, they can be divided into: horizontal sedimentation, radial sedimentation, vertical sedimentation and inclined tube sedimentation.

1、 Advection sedimentation

This type of sludge settling device has the advantages of good settling effect, easy construction, strong adaptability to the change of impact load and temperature, etc. The disadvantage is that it needs a large area, and the work operation management is more complex, and the workload is large.

2、 Radial flow precipitation

      This type is mostly used in large-scale sewage treatment plant, but less in the field of sewage treatment in sand making, mineral processing and other industries. The utility model has the advantages of good operation effect and convenient for mechanical mud scraping, but at the same time, because the water flow in the pool is not easy to be uniform, the flow rate is not stable, the sedimentation effect is poor, the requirements for construction quality are high, and the operation management is complex.

3、 Vertical flow sedimentation

       Vertical flow sedimentation tanks are mostly used in small and medium-sized sand and gravel sewage treatment systems (the concentration tank of hydrogen purification body produced by Doyen China is a vertical flow sedimentation device). The utility model has the advantages of small floor area and convenient sludge discharge, and the disadvantage is that the construction of the sedimentation tank is difficult and the cost is high due to the large depth of the tank.

4、 Inclined tube plate sedimentation

       This type is widely used as secondary sedimentation in sand and gravel wastewater treatment system. Its advantages are good hydraulic conditions, high sedimentation efficiency, small volume, less land occupation, and its disadvantages are much smaller materials and higher operation cost.

       The concentration tank of the three hydrogen purification body is a fast concentration and purification device designed and developed by Doyen China, a mud treatment equipment manufacturer, for the problems of the sand washing wastewater in the sand washing industry, such as difficult treatment, unable to effectively recycle, large environmental pollution and high treatment cost. Compared with the sewage settling facilities used in most domestic projects, the equipment has the advantages of fast processing speed, small floor area, less equipment failure and so on. It is an ideal equipment for various sand making and beneficiation enterprises to concentrate sewage sludge! The equipment is a vertical flow sewage settling device, which retains the advantages of the type of small floor area, convenient sludge discharge and so on. At the same time, due to the high degree of integration of the equipment, not only the construction is convenient, but also the equipment can operate automatically, with high efficiency and very small operation cost.
