Example Embodiment
[0030] Example 1: Fermentation device for sludge composting.
[0031] Kind of like figure 1 The fermentation device for sludge composting treatment of the present invention is shown. The fermentation device of this embodiment is designed according to the processing capacity of 5 t, 80% moisture content sludge (can be adjusted according to the amount of sludge produced per day ). The fermentation device for sludge composting treatment of the present invention includes a fermentation bin body 1, which is a steel plate welded angle iron reinforced cylindrical closed fermentation bin (diameter d=2 m, height h=2.75 m); The bottom of the body 1 is externally connected with a forced ventilation device 3 (this embodiment is an intermittent static forced ventilation device); the bottom of the fermentation bin body 1 is laid with a filter layer, which includes a 20 cm thick gravel layer 12 (stone diameter 10 mm~20 mm) and the barbed wire 13 under the gravel layer 12 (the diameter of the ...
Example Embodiment
[0032] Example 2: Treatment method of sludge composting.
[0033] In the sludge composting treatment method of the present invention, the sludge raw materials to be processed are collected from Qianfeng Sewage Plant, Shiqi Town, Panyu District, Guangzhou City, which is a typical small sewage treatment plant. The sludge raw materials are dehydrated by a belt filter press Afterwards, a dehydrated sludge with a moisture content of about 80% is obtained. The dehydrated sludge is placed in an oven at 105°C for 24 hours to obtain dry sludge. The content of volatile organic compounds in the dry sludge is 52.90%, and the C / N ratio is about Is 8.5. Composting the dehydrated sludge with a moisture content of 80% using the treatment method of the present invention and the fermentation device in Example 1 specifically includes the following steps:
[0034] (1) Add organic conditioning agent: add organic conditioning agent to the dehydrated sludge to be treated to adjust the moisture content,...
