Vertical type no-layering sludge aerobic fermentation system and treatment method

Abstract

The invention discloses a vertical type no-layering sludge aerobic fermentation system and a treatment method. The fermentation system comprises a fermentation bin, air supply devices and a discharge device, wherein support bodies are arranged in the fermentation bin; each air supply device comprises multiple air supply units arranged on two opposite side surfaces of the fermentation bin; an oxygen sensor and a temperature sensor are arranged between adjacent air supply units, and the discharge device is arranged at the bottom end of the fermentation bin. The treatment method comprises steps as follows: a mixed material containing the support bodies is sent to the fermentation bin; the air supply devices are controlled according to the oxygen sensors and the temperature sensors, so that the material is subjected to aerobic fermentation; after aerobic fermentation is completed, the mixed material containing the support bodies is output; the support bodies and the mixed material are separated through screening. According to the vertical type no-layering sludge aerobic fermentation system and the treatment method, the mixed material and the support bodies are mixed, the stacking height of the mixed material is increased by means of a lateral distributed intelligent air supply system, the land occupation area is reduced, the oxygen environment distribution is uniform, and energy is saved.

Description

technical field [0001] The invention relates to a sludge treatment equipment, in particular to a vertical non-layered sludge aerobic fermentation system and a treatment method. Background technique [0002] With the rapid development of my country's economy, the problems of shortage of water resources and serious water pollution in my country have become increasingly prominent. In order to control and alleviate the current situation of water pollution, a large number of sewage treatment plants have been built in my country. According to statistics, by the end of 2011, there were 2,996 urban sewage plants in my country, with a daily treatment capacity of 112.44 million square meters. At the same time, at present, the amount of sludge discharged by my country's urban sewage treatment plants is about 9 million tons (calculated with 80% water content, the same below), and it is increasing at a rate of 10% every year. Therefore, a huge amount of sludge needs to be obtained urgen...

Problems solved by technology

[0011] In view of the problems existing in the above-mentioned prior art, the present invention proposes a vertical non-layered sludge aerobic fermentation system and treatment method, in which an artificial support is mixed into the mixed material in the fermentation bin to act as a support for the mixed material in the heap With the function of the skeleton, the gravity of the upper mixed material can be transmitted downward through the supporting structure that is connected with each other until it acts on the bottom plate, which can prevent the lower mixed material from being directly compacted by the gravity of the upper mixed material, and can effectively increase the stacking height , and can ensure the ventilation of the pile, which solves the problem that the fermentation bin in the prior art can only be piled up to about two meters, requires a lot of leavening agents and conditioners, and has high costs; in addition, a lateral distributed intelligent air supply system is adopted , which can not only ensure the uniformity of the oxygen environment in the fermentation chamber, but also save energy
