Problems solved by technology

When the ventilation rate is small, it will cause low oxygen content, which is not conducive to the survival of aerobic microorganisms; when the ventilation rate is large, it is not conducive to maintaining the temperature of the pile and will increase the release of volatile gases

Embodiment 1

[0034] Dewatered sludge (moisture content 79.8%) and conditioner (moisture content 8%) are uniformly mixed in a certain proportion, so that the initial moisture content is about 64%, and the materials are respectively added to two fermentation tanks for fermentation.

[0035] The temperature of the two tanks varies with time as follows: figure 2 and image 3As shown, the fermenter that does not use the portable sludge aerobic fermentation intelligent diagnosis system for fermentation has difficulty raising the temperature after the fermentation starts, and the time to reach the high temperature period (60°C) is as long as 6.5 days, resulting in a long fermentation cycle and affecting production efficiency ( image 3 ).

[0036] A portable sludge aerobic fermentation intelligent diagnosis system was used for diagnosis, and it was found that the main reason was that the ventilation volume in the early stage was too large, and the temperature would drop after each blast, and t...

Abstract

The invention discloses a portable intelligent sludge aerobic fermentation diagnosis system which comprises an intelligent blower control part and an automatic fermentation process monitoring part; in the intelligent blower control part, a PLC is connected with a blower and is used for controlling the operation of the blower in a programming manner to realize intelligent, timed, quantitative and precise air blowing; the automatic fermentation process monitoring part is used for on line monitoring and recording the temperature and oxygen conditions of the sludge fermentation process in real time and used for feeding back the monitored and recorded temperature and oxygen conditions to adjust and control the fermentation process. As the blower is connected with the PLC used for controlling the operation of the blower in a programming manner to realize intelligent, timed, quantitative and precise air blowing; and meanwhile the temperature and oxygen conditions of the sludge fermentation process are monitored and recoded on line in real time through the automatic fermentation process monitoring part and further fed back to adjust and control the fermentation process, so that the automatic diagnosis and adjustment on sludge aerobic fermentation are achieved and the success of sludge aerobic fermentation is ensured.

Description

technical field [0001] The invention relates to a diagnosis system, in particular to a portable sludge aerobic fermentation intelligent diagnosis system. Background technique [0002] In the actual operation of the sludge aerobic fermentation disposal plant, there are often problems such as unstable fermentation operation of the fermentation tank, difficulty in raising the temperature of the fermentation, insufficient high temperature duration, and more odor release, which eventually lead to fermentation failure. Therefore, it is necessary to carry out intelligent diagnosis on the sludge aerobic fermentation process, and find out the reason of fermentation failure in time and quickly. During the sludge aerobic fermentation process, once the fermentation process starts, the fan becomes the only control means, and the aerobic fermentation process includes a series of process parameters, including temperature, oxygen content, ammonia concentration, hydrogen sulfide concentratio...
