Description

Multifunctional anaerobic tank water distribution and sludge discharge device Technical Field The utility model relates to the technical field of leachate sewage treatment equipment, in particular to a water distribution and sludge discharge device of a multifunctional anaerobic tank. Background At present, in the leachate sewage treatment process, an anaerobic tank is most commonly used for decomposing organic substances and converting organic wastes into biogas. In the actual operation process of the anaerobic tank, the problems of sludge deposition and scaling seriously affect the treatment efficiency and the operation stability. Wherein, because of the too high concentration of calcium and magnesium ions in the sludge deposition and scaling process, scaling is easy to generate, and the scaling cannot be avoided, thereby causing water outlet blockage and directly affecting the treatment efficiency of the anaerobic tank. Thus, the problem of sludge deposition is a major problem in the operation of anaerobic tanks. Since sewage contains a large amount of suspended substances and colloidal substances, these substances gradually precipitate and accumulate at the bottom of the anaerobic tank during the anaerobic reaction. If the deposited sludge cannot be discharged comprehensively and effectively, the sludge is accumulated in the tank continuously. On one hand, excessive sludge accumulation occupies the effective volume of the anaerobic tank, reduces the sewage treatment capacity and the equipment treatment capacity, and on the other hand, long-term sludge deposition can cause sludge aging and hardening to influence the activity and the metabolic function of anaerobic microorganisms, thereby reducing the anaerobic reaction efficiency and the treatment effect. Secondly, the concentration of calcium and magnesium ions in the leachate sewage is too high, scaling is easy to generate, and the inner diameter of the pipeline is reduced. If the water outlet pipeline is blocked seriously or even completely due to scaling, the water flow section is reduced, and the water flow resistance is increased, so that the water outlet is not smooth, and the normal operation of the sewage treatment system is affected. In the sludge discharge pipe, the scale formation may hinder smooth discharge of sludge, cause sludge accumulation, and may also cause equipment malfunction, increasing maintenance costs and downtime. In view of the foregoing, it is desirable to provide a multifunctional anaerobic tank water distribution and sludge discharge device to overcome the above-mentioned drawbacks. Disclosure of utility model The utility model aims to provide a multifunctional anaerobic tank water distribution and sludge discharge device, which aims to solve the problem that a sludge discharge pipeline of an anaerobic tank is easy to scale, and a sludge discharge system can be backwashed through an external water inlet pipeline, so that the scale of the pipeline is slowed down, the maintenance period is prolonged, and the overhaul cost is reduced.
