Embodiment Construction

[0014] The pretreatment facilities at the source of domestic sewage outside the sewage treatment plant are built into high-level mud storage and digestion tanks. A large number of high-level mud storage and digestion facilities are distributed in the living areas outside the sewage treatment plant, and the sewage generated in the sedimentation tank of the sewage treatment plant Sludge is divided into small batches, and transported to multiple high-level sludge storage and disposal facilities by sludge trucks, and the sludge is input at the front end of the high-level sludge storage and treatment facilities. The amount of imported sludge does not exceed the high-level sludge storage and treatment In the container space of one or more grids at the front end of the facility, when the sludge at the front end of the high-level sludge storage and treatment facility has been digested and decomposed for a long time and stabilized, the stabilized sludge will The sludge will continue to ...

Abstract

The invention provides a method for treating sludge by gathering, distributing and accommodating. The method is mainly characterized in that a sludge treatment mode of breaking up the whole into parts is adopted, a plurality of high-level stored sludge accommodation treatment facilities are established outside a sewage treatment plant, so that the sludge generated by the sewage treatment plant is transported into the high-level stored sludge accommodation treatment facilities in batches to be stabilized, the stabilized sludge is stored in the high-level stored sludge accommodation treatment facilities for a long time, or is cleared and transported to a sludge disposal site to be finally treated. According to the method, the problem that a large space is occupied when sludge stable treatment is performed in the sewage treatment plant by adopting a sludge gathering, distributing and accommodating technology, and a solution for treating the gathered sludge in a dispersed mode is formed.

Description

technical field [0001] The invention relates to a method for sludge treatment and disposal. Background technique [0002] The principles of sludge treatment and disposal are stabilization, harmlessness, and resource utilization. A large amount of sludge produced by domestic sewage treatment facilities includes degradable sludge and refractory sludge, most of which are degradable Sludge, according to the principle of sludge balance and consumption, there is a limit to the cumulative growth of degradable sludge. When the sludge input and sludge decomposition reach a balance, the total amount of degradable sludge is in a balanced state, accounting for a small part The refractory sludge is the sludge that accumulates linearly and grows. Let the degradable sludge be fully decomposed, and other refractory sludge will become stabilized sludge. Stabilization of sludge can be achieved through anaerobic digestion, and sludge digestion and decomposition The longer the time, the higher...
