Embodiment Construction

[0024] A treatment method for sludge, the treatment method has the following steps to achieve:

[0025] ⑴. After the primary treatment, the sludge with a water content greater than 70% is added to the treatment liquid and water for uniform stirring treatment. The water content of the treated sludge is 90-98%:

[0026] ⑵. The sludge uniformly stirred in step ⑴ is subjected to a group of cutting and crushing treatments with different particle sizes according to its flow direction:

[0027] Since the sludge structure contains solids, intermediate water between solids, and microscopic water-containing particles of different sizes formed by solids, the water-containing particles account for a considerable proportion of the water content of the sludge. If the water-containing particles are not protected Dehydration of the sludge until the water content is less than 75% will consume huge energy, such as increasing the dehydration pressure, increasing the dehydration temperature and d...

Abstract

The invention relates to a sludge treatment method and treatment system, which realize deep sludge dewatering and create technical conditions for recycling comprehensive utilization of sludge. The treatment method comprises the following steps: (1) regulating the water content of sludge; (2) cutting and crushing the sludge; (3) performing flocculation and filtration aid treatment; (4) draining and dewatering; (5) adding environmental mineral materials; (6) heating, and loosening; and (7) removing moisture. The treatment system adopts a treatment device, wherein the treatment device comprises a storage bin, a shearing dispersion machine, a treatment bin, a draining bin, a slurry pump, a filter press, an ingredient mixing machine, a heating and extruding machine, a loosening and drying machine and a discharging mechanism; the storage bin is connected with the shearing dispersion machine; the shearing dispersion machine is connected with the treatment bin; the treatment bin is connected with the draining bin; the draining bin is connected with the slurry pump; the slurry pump is connected with the filter press; the filter press is connected with the ingredient mixing machine; the ingredient mixing machine is connected with the heating and extruding machine; the heating and extruding machine is connected with the loosening and drying machine; and the loosening and drying machine is connected with the discharging machine. According to the invention, the treatment method is simple, short in process flow and low in treatment cost; and the treatment device is compact in structure, has favorable operation stability and reliability, causes no pollution in the treatment process, and is beneficial to popularization.

Description

technical field [0001] The invention relates to the field of sludge treatment in the field of environmental protection, in particular to a sludge treatment method and a treatment system thereof. technical background [0002] A large amount of sludge is produced in the waste water and various garbage produced in human life. The sludge has become a difficult problem in environmental protection. How to treat the sludge scientifically and environmentally friendly to reduce environmental pollution and resource utilization or return to nature has become a problem. It will become an urgent technical problem to be solved in the industry. [0003] In the prior art, the treatment of sludge is mainly adopted: landfilling sludge—in fact, passively "escaping" sludge, wasting resources, occupying land, and becoming a source of pollution. Incineration of sludge—essentially extreme “elimination” of sludge, using expensive fuel energy to eliminate non-renewable loam resources and secondary ...
