Movable sludge reduction treatment device and process thereof

Abstract

The invention discloses a movable sludge reduction treatment device and a process thereof. The device comprises a raw sludge tank which is connected with a steam explosion machine; the steam explosionmachine is respectively connected with a water vapor absorption mechanism and a sludge storage tank group; the sludge storage tank group is connected with a fermentation tank; wherein the raw mud pool and the steam explosion machine, the steam explosion machine and the mud storage tank group, and the mud storage tank group and the fermentation tank are respectively connected through conveying mechanisms; and the steam explosion machine and the sludge storage tank group are arranged in the movable box body. According to the technical scheme, the steam explosion machine and the sludge storage tank group are arranged in the movable box body; the structure has the advantages that on-site treatment of sludge can be realized, and the transportation cost of the sludge is reduced; due to the facts that the occupied area of the device is small, and the steam explosion machine and the sludge storage tank set can be moved in a vehicle-mounted mode, the device is suitable for the situation that at present, land resources are insufficient, and production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a mobile sludge reduction treatment device and a process thereof. Background technique [0002] With the development of the economy, the amount of urban sewage continues to increase. According to relevant forecasts, the current annual output of dry sludge in my country is very high. Municipal sludge contains a large amount of N, P, K, Ca and organic matter, and N and P are mainly in organic state, which can be released slowly and have long-term effect. Sludge is a useful biological resource, and if it can be used rationally, it can turn waste into treasure. [0003] Sludge treatment is the harmless processing of sludge, including the removal of heavy metals, pathogens, insect eggs, carcinogens, and organic macromolecules in sludge. The existing relatively new sludge treatment methods mainly include sludge wet oxidation method and membrane bioreactor treatment method. ...

AI Technical Summary

Problems solved by technology

[0004] The sludge wet oxidation method is mainly suitable for the treatment of various refractory organic sludge. The disadvantage is that the equipment is complex and the operation and maintenance costs are high.

The residence time of the sludge in the membrane bioreactor of the membrane bioreactor treatment method is very long, resulting in a long process time, low treatment efficiency, and even avoiding sludge discharge, but the clogging of the membrane and the price of the membrane material limit the promotion of this method application

[0005] Moreover, the limited sludge treatment process takes up a lot of space, resulting in relatively high costs. Therefore, a method that fully meets the requirements of reduction, harmlessness, stabilization, and resource utilization can be realized at the same time with a small footprint and high flexibility. High sludge treatment device is just the problem to be solved by the inventor
