Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] A sludge reduction treatment system, such as attached figure 1 As shown, it includes a first cylinder 1, a second cylinder 2 and a feed pipe 3; the outlet end of the feed pipe 3 is correspondingly arranged above the first cylinder 1, and the sewage to be treated flows in from the feed pipe 3 In the first cylinder 1, the sewage here refers to the mixture of sludge and water with high water content before reduction treatment; the side wall of the first cylinder 1 is provided with a number of first filter windows 12 , the bottom is connected with a sludge discharge pipe 11; after the sewage enters the first cylinder 1, the sludge part is deposited downward under the action of gravity and then sucked away by the sludge discharge pipe 11, while the water in it is under the action of static pressure After filtering through the first filter window 12, it reaches the o...

The invention discloses a sludge reduction treatment system which comprises a first barrel, a second barrel and a feed pipe, wherein an outlet end of the feed pipe is correspondingly arranged above the first barrel; sewage to be treated flows into the first barrel through the feed pipe; a plurality of first filtration windows are arranged in a side wall of the first barrel; a sludge discharge pipeis communicated with and arranged at the bottom of the first barrel; the first barrel is sleeved by the second barrel; a filtration cavity with an opening in the upper end is defined by the second barrel and the first barrel; a plurality of second filtration windows are arranged in a side wall of the second barrel; a wastewater pool is correspondingly arranged below the second barrel; two-stage filtration of the sewage has the advantages that part of sludge and water can be quickly separated in a smaller container through the first filtration windows with larger pore sizes and then fine filtration is accomplished by the filtration cavity with a larger volume; the two-stage filtration avoids the problems of easy blocking and easy accumulation due to slow treatment in the traditional singlefiltration; and the working efficiency of the system is significantly improved.
Description
technical field [0001] The invention relates to sludge treatment technology, in particular to a sludge reduction treatment system and a sludge treatment process method thereof. Background technique [0002] Sludge from industrial production not only has rot and a strong pungent smell, but also contains a large number of germs, heavy metals and carcinogens. If these sludges are allowed to be piled up or directly buried, it is very easy to pollute nearby large areas of soil and groundwater resources, endangering the environment and human health. As a process for stabilizing and improving sludge composition, thermal hydrolysis is often combined with subsequent digestion processes to effectively degrade sludge and convert it into combustible gas for resource recycling. Some sludge is mixed with a large amount of sewage and enters the treatment system. Before thermal hydrolysis, there is another important step is sludge reduction, which is to remove a large amount of water in it...
