Problems solved by technology

In this process, since the moisture content of the compost product is as high as 70% to 80%, the moisture content of the dung residue is high, the degree of reduction is not high, and the cost of subsequent treatment is relatively high

Embodiment Construction

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Please refer to figure 1 Shown, below in conjunction with embodiment description a kind of dehydration method of fecal sludge sewage advanced conditioning, its method flow process is:

[0019] First of all, collect all the fecal sewage in the septic tanks into the excrement collection tank, and then use the pipeline pump to pump the fecal sludge sewage from the fecal collection tank into the fecal conditioning tank, and then, A conditioning catalyst is added inside the dung slag conditioning tank, and the agitator installed inside the dung slag ...

Abstract

The invention relates to a dehydration method for deep conditioning of dung sludge sewage. The dehydration method comprises the following steps: a dung sludge sewage solution is pumped into a dung sludge conditioning pool through a pipeline pump; a multistage treatment technology of carrying out a chemical reaction, a plant liquid micro-mist reaction and an alkaline washing reaction on componentscontained in the dung sludge sewage in sequence by a conditioning catalyst is adopted, so that the dung sludge sewage is subjected to dehydration, carboxyl free radical oxidized refractory substancesare decomposed, pollutants, alkaline and acidic stink in waste gas are removed, and a dung sludge sewage solution is formed; then an extruding, heating and deep dehydration processes are carried out on the dung sludge sewage solution through a plate-frame diaphragm filter press, so that the water content of dehydrated dung sludge is 20% or lower; and in addition, most bacteria are killed by high temperature. The water content of dehydrated dung sludge residues is greatly reduced, so that the reduction degree of treatment of dung garbage is improved. Moreover, the dung garbage residues can be used for preparing organic fertilizers or biomass dyes, so that balance of the natural ecological environment is protected.

Description

【Technical field】 [0001] The invention relates to a dehydration method and a dehydration device used in the advanced conditioning of feces, sludge, and sewage in the field of environmental protection. 【Background technique】 [0002] With the increasing population of the society, more and more feces are produced by consumers every day. However, in the current existing technology, in order to solve the pollution caused by the treatment of feces to the surrounding environment, generally, feces are used. The harmless treatment technology of slag sewage, its process is that the dung enters the grill machine through the discharge pipe, and the large solid matter in the dung sludge is removed by the grill machine, and the dung sludge is formed after the debris. After the sludge is dehydrated, it enters the composting stage, and after a period of high-temperature aerobic fermentation, composting products are formed. During this process, since the moisture content of compost product...
