With the increasing attention paid by the country to sewage treatment and rectification work, some enterprises still do not have complete knowledge of domestic sewage treatment equipment. Here, the editor will introduce how domestic sewage treatment equipment operates. Domestic sewage treatment equipment is a commonly used sewage treatment equipment in daily life, and there is a sedimentation process during the treatment of sewage. So, how does domestic sewage treatment equipment precipitate?

1、 Domestic sewage treatment equipment is generally free settling, with low concentration of suspended solids, and the settling process does not change the shape of particles.

2、 Flocculation and sedimentation of domestic sewage treatment equipment can occur during the sedimentation process, which is a type of sedimentation of low concentration virtual floating particles. Due to the increase in particle mass caused by flocculation, the sedimentation rate accelerates and increases with depth.

3、 At the interface of domestic sewage treatment equipment, sedimentation occurs. When the concentration of suspended solids in the sewage increases to a certain value, due to the interference between particles, all particles precipitate as a cluster, forming a clear and visible mud water interface between the sludge and water. At this time, all particles have the same sedimentation rate and precipitate at the same speed. The lower part of the activated sludge secondary sedimentation belongs to this type.

4、 The compaction sedimentation of domestic sewage treatment equipment occurs during the sedimentation process of high concentration solid particles. Due to the high SS, the particles aggregate and support each other, and the moisture between the base particles is pressed out by the gravity, water depth, and self gravity of the upper particles, resulting in the concentration of sludge. The concentration process in the sludge hopper of the secondary sedimentation tank and the concentration process of the sludge in the concentration tank are subject to contraction sedimentation.

The above is an introduction to how domestic sewage treatment equipment settles. Sedimentation is an important process in domestic sewage treatment equipment, and sewage is transformed into water that meets discharge standards through many steps. Each step is essential.
