Sludge heatless drying treatment device and method

Abstract

The invention provides a sludge heatless drying treatment device and method. The sludge heatless drying treatment device comprises an extrusion mechanism, a filtering mechanism, a strip discharging mechanism, an adjusting mechanism and a drying mechanism; the filtering mechanism is arranged at the left end of the extrusion mechanism, a collecting device is arranged on the filtering mechanism, and the collecting device comprises a second flow meter, a first alarm and a first controller; the strip discharging mechanism is arranged at the left end of the filtering mechanism; the adjusting mechanism is arranged at the left end of the strip discharging mechanism; and the drying mechanism is arranged at the left end of the adjusting mechanism. According to the sludge heatless drying treatment device and method, water in sludge can be discharged through extrusion, the sludge is dried through filtering, strip discharging and drying, heating and drying are not needed, and energy is saved; meanwhile, the water outlet amount of the filtering mechanism is detected through the second flow meter, and when the water outlet amount is smaller than the preset water outlet amount, the first controller controls the first alarm to give out an alarm prompt; and a worker is reminded to overhaul the filtering mechanism, so that the filtering performance of the filtering mechanism is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sludge athermal drying treatment device and method. Background technique

[0002] In human production and life, a large amount of sewage and sludge will be produced, such as domestic sludge, construction sludge, industrial sludge, etc., especially the sludge output of wastewater treatment plants is larger, and the sludge of wastewater treatment plants has a high water content. , high organic matter content, difficult dehydration, easy corruption and odor, etc., if not handled properly, it will cause serious secondary pollution, which has become a common environmental problem faced by all cities and towns. The core issue of sludge treatment is dehydration. Only when the moisture content of sludge is reduced to a certain level can subsequent final disposal, such as incineration, pyrolysis, composting, landfill, etc. be carried out.

[0003] At present, sewage treatment ...
