Description

High-efficient solid-liquid separation equipment of independent assortment formula

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to high-efficient solid-liquid separation equipment of independent assortment formula.

Background

A precipitation separation process commonly adopted in the water treatment technology is mainly a sedimentation tank. In the 20 th century before the 60 th, advection type, vertical type and radial type sedimentation tanks were mainly adopted, and in the first time of the 60 th, various clarification tanks were prevalent, and in the 70 th, inclined tube and inclined plate sedimentation tanks were mainly adopted. Early settling ponds had much lower efficiency, both deep and occupied area. The efficiency of the inclined plate or inclined tube sedimentation tank designed according to the shallow tank theory is obviously improved, and the actual efficiency is usually 7-10 times that of the horizontal flow sedimentation tank. Because the water flow between the inclined pipes (plates) is in a laminar flow state, the hydraulic radius is small, the Re value is low, the Fr is high, and the hydraulic condition is good, the sedimentation and separation are more facilitated. The efficient sedimentation can save a large amount of construction land for water treatment engineering, the inclined tube (plate) sedimentation tank can be divided into an upward flow mode, a downward flow mode and a lateral flow mode, and the upward flow inclined tube (plate) is successfully applied to the engineering.

However, the upward inclined tube (plate) sedimentation tank still has some problems in practical engineering application:

(1) the falling sludge separated by the inclined pipe/inclined plate and the separated clear water occupy a channel, and mutual interference is formed between the falling sludge and the separated clear water, so that the sludge discharge effect is not ideal.

The inclined tube (plate) sedimentation tank separates the lower sludge from the upper clear water by using the inclined tube (plate), and achieves the purpose of purification by using the sedimentation of water in the rising process. And the sludge particles that precipitate and descend are easily supported by the top of the rising clear water in the descending process, and some smaller sludge particles can float to the top of the inclined tube to form secondary flocculation deposition, so that the precipitation effect is influenced.

(2) Sludge is easy to deposit in the inclined tube (plate) to block the inclined tube, and particularly, a large amount of accumulated sludge is retained at the top of the inclined tube, so that the inclined tube is easy to block or collapse along with the lengthening of the operation time. The main reason for this problem is that the honeycomb or rectangular structure of the inclined tube/plate is liable to form a lateral restraining force at the included angle when the surface sludge slides down, which hinders the sludge from sliding down, thereby causing vicious circle and finally blocking the inclined tube.

In practical engineering, every time the inclined tube (plate) sedimentation tank operates for a period of time, the tank is frequently emptied and washed manually, so as to ensure smooth production.

(3) Algae are easy to breed in the sedimentation tank, water outlet holes are blocked, and the water purification efficiency is reduced.

Because the effluent of the inclined tube (plate) sedimentation tank is arranged at the upper part and the clear water has larger area, a large amount of algae can be bred under the irradiation and transmission of sunlight to block the water outlet hole of the water collecting tank, so that the water collecting tank needs to be manually cleaned, and the operation is very troublesome.
