Description

The sludge dewatering solidification processing method
Technical field
The present invention relates to a kind of sludge treatment technology, especially relate to a kind of efficient, less energy-consumption, be easy to the sludge dewatering solidification processing method of the desilting mud of operational management.
Background technology
The mud that produces in dredging engineering often adopts the stacking mode or is transported to the off-lying sea and does and abandon processing, and such processing mode or take a large amount of land resourcess perhaps has a strong impact on effective utilization of oceanic resources.Mostly contain in addition the pollutents such as heavy metal, organic matter in mud, this just will inevitably cause to soil and ocean environment the severe contamination of destruction.
At present, the discarded restraining factors that become China's river management and oceanographic engineering development of dredging silt, dredging silt has caused the attention of personages of various circles of society and relevant departments on the impact of environment.Therefore, the development of sludge treatment technology has very important meaning for environment protection.
As far back as late 1980s, Britain, France, Sweden, Holland and the developed country quite a lot such as Australian have just carried out comprehensive development and utilization in the commercialization mode to mud.Britain, France have begun to utilize mud to be main raw material, make high-efficient purification fuel, and its calorific value exceeds 30% than common coal, and can not give off obnoxious flavour in combustion processes; Germany has developed the factory that mud was collected, processed in many families specially, and a year treatment capacity reaches more than 300,000 tons; Japan has begun to produce all kinds of material of construction with mud.The fragment of brick of making take mud as main raw material has good permeability, lightweight, and color is the advantage such as modulation easily, has become the best-selling goods of world market.Yet in China, due to technical elements, mud there is no reasonable outlet.The mode of utilizing for mud only limits to agriculturally as fertilizer.
The sludge solidification treatment technology that adopts both at home and abroad at present is physics dewatering and coagulating and high-temperature digestion sintering.Adopt the physics method for airing need take the big area place, and be subject to weather effect, processing efficiency is low, is difficult to satisfy the requirement of large-scale dredging engineering; Employing high-temperature digestion sintering method disposal mud expense is high, treatment capacity is limited.
Summary of the invention
In the lake dredging up process of sea, current river, mud exists and is untreated or the drawback such as processing efficiency is low, the purpose of this invention is to provide a kind of efficient, less energy-consumption, has been easy to the sludge dewatering solidification processing method of the desilting mud of operational management.
The present invention realizes by following technical measures, and a kind of sludge dewatering solidification processing method comprises following steps:
(1), sandstone separates: the mud in the Jiang Hai lake is extracted out through pipeline, separated, sandstone discharged after washing through sand-gravel separation device, rest part enters settling tank;
(2), solid-liquid initial gross separation: add flocculation agent in settling tank, the weight ratio of mud and flocculation agent is 5: 0.01, and the mixed solution of gained is slightly made the standing effect that just reaches preliminary solid-liquid separation;
(3), add solidifying agent: add solidifying agent in the mud of step (2) gained, the weight ratio of mud and solidifying agent is 10: 1, stirs after dosing, and mud and solidifying agent are mixed;
(4), press filtration: mud press filtration 20min under 0.6MPa pressure of step (3) gained realizes further mud-water separation, obtains the silt consolidation body of water ratio<30%;
(5) draining: the water that produces in step (2) and step (4), is discharged after processing to water treatment system through pipe influx.
As a kind of optimal way, the sand-gravel separation device in described step (1) adopts high strength manganese steel roller separation screen cloth and drum-type to clean, and sandstone is separated and wash afterwards and discharge.
As a kind of optimal way, the flocculation agent in described step (2) comprises main solidifying agent: polymerize aluminum chloride, compound coagulant aids: compound diatomite, sorbent material: phosphoric acid salt and conditioning agent: sulfuric acid lime.Add in proportion according to amount of sludge in practical application, dosing is through stirring postprecipitation 10min.
Concrete, the weight ratio of described solidifying agent each component is cement 10~30, flyash 30~60, lime 20~30, kaolin 3~5 and promoting agent 0.5~1.
The invention belongs to the chemosetting method, adopt this method that mud is disposed, processing efficiency is high, easy construction, and is easy to apply, and adopts the present invention to process gained silt consolidation body water content<30%, can be used as the road base layer filler, and is respond well.The core of the technology of the present invention is to solidify to take off dry systems, the present invention integrates the functions such as sandstone separation, flocculation sediment, chemosetting and filter-press dehydration, and make two moisture in treatment step from, converge, recycle after simple process, this technology has reached resource utilization and the water circuit recycling of mud simultaneously.
Mud after processing through the present invention, not only processing efficiency is high, and reduced investment, and running cost is low, can reach the engineering application level; Isolated water is as clear as crystal when water treatment system is discharged, and the SS value is less than 20mg/l.
