Sludge slurry treatment method and integrated system

Abstract

The invention belongs to the technical field of sludge slurry treatment, and particularly discloses a sludge slurry treatment method and an integrated system. The sludge slurry treatment method comprises the steps: S1, evenly stirring and feeding sludge slurry into a curing agent stirring box, adding a curing agent into the curing agent stirring box and stirring, and obtaining slurry-curing agentmixed slurry; S2, pumping the slurry-curing agent mixed slurry into a flocculating agent stirring box, uniformly adding a flocculating agent solution in the pumping process, and then stirring to flocculate and deposit the slurry-curing agent mixed slurry to obtain slurry-curing agent-flocculating agent mixed slurry; S3, pumping the slurry-curing agent-flocculating agent mixed slurry into a filterpress for dehydration to obtain a mud cake, and treating the mud cake through a granulating device to obtain mud particles. The sludge slurry with ultrahigh water content is directly converted into dense mud particles through the integrated flocculation conditioning-filter pressing dehydration-granulation device so that the problem that the tail end of a huge amount of sludge slurry is difficult to dispose can be effectively solved, and the obtained mud particles and plain soil mixed filler can relieve the dilemma of serious shortage of sandstone filler.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and more specifically relates to a sludge treatment method and an integrated system, especially a high water content sludge for civil engineering, port channel engineering, river and lake dredging engineering, etc. An all-in-one system and method for rapid processing. Background technique [0002] Every year, due to the treatment of the water environment, a large amount of dredging mud will be produced from port terminals, waterways and inland rivers and lakes, and there will be nowhere to place a large amount of engineering mud due to engineering construction (hereinafter, dredging mud and engineering mud are collectively referred to as ultra-high water content sludge). How to quickly and effectively deal with such a huge amount of ultra-high water content sludge has always been a difficult problem for the engineering community. At present, the following methods are mainly used for th...

Problems solved by technology

[0007] In view of the above defects or improvement needs of the prior art, the present invention provides a sludge treatment method and an integrated system, the purpose of which is to directly convert ultra-high water content The conversion of silt slurry into dense silt particles can effectively solve the problem of difficult disposal of a huge amount of silt slurry with ultra-high water content at the end. At the same time, the obtained filler mixed with mud particles and plain soil can alleviate the severe shortage of sand and gravel filler to a certain extent. , and the operation is simple and efficient
