Description
Technical field
The utility model belongs to environmental technology field, particularly a kind of sludge treatment equipment.
Background technology
Along with the municipal sewage treatment Facilities Construction progressively raise speed with the sewage centralized treatment rate improve the sharp increase of sludge of sewage treatment plants generation day by day.According to relevant prediction, China's municipal effluent amount also has in next two decades and increases substantially, and quantity of wastewater effluent will reach 440 * 108m3/d in 2010; The year two thousand twenty quantity of wastewater effluent reaches 536 * 108m3/d; Sludge quantity accounts for 0.3%～0.5% (volume) of sewage quantity usually or is about 1%～2% (quality) of sewage load.And if sewage is carried out advanced treatment again, sludge quantity also can increase by 0.5～1 times.At present wastewater treatment in China amount and processing rate not high (4.5%), and annual about 9,000,000 t of mud that discharge in municipal sewage plant, but also with the speed increment in every year about 10%.Lagged behind the greatly paces of China environmental protection and improvement of the severe situation that sewage sludge harmlessness is handled have caused showing great attention to of government and relevant departments.
Country " 12 " planning, will increase day by day 4,500 ten thousand tons of sewage treatment capacity of China, the centralized treatment of urban sewage rate reaches 70%, and China's mud generation is also unprecedented soaring.And municipal sludge have capacity big, unstable, be prone to characteristics such as corruption, foul smelling, poisonous and harmful, do not handle or mishandlingly will cause serious secondary pollution accidents such as pollutent invasion underground water, foul gas erosion atmosphere.
At present; Deeply dehydrating sludge is most, and what adopt is lime mummification dehydration technique, this technology before use, must be first to first mud dewater (first moisture percentage in sewage sludge about 96%); Preposition dehydration floor space is big; This technology takies plant area's land used in a large number also need outside the dehydration car, building between truck with grout mixer and water tank and the airing workshop after the use, and the sludge treatment expense is high.And the mud that produces in the WWT has higher water ratio, because moisture and mud granule bonded characteristic, contains a large amount of surface water and capillary waters that determined by its surface property and mud unity structure in the mud.This type moisture is by solid particulate absorption or be wrapped in granule interior; Because it is firm by the very powerful negative charge in periphery; And average out with positive charge in the water nuclear, adopts traditional dewatering machine to handle and have certain restriction, can only slough free water partly; Therefore, the conventional dehydration processing unit only can be handled water ratio 70%-80%.
The sludge treatment technology that sludge modification press filtration drying technique is up-to-date is with high-pressure compressing, in conjunction with the mode of chemical conditioning, destroys the irreducible water structure earlier, changes it into free water, cooperates high-pressure compressing again, can the water ratio of sludge dewatering be reduced to below 45%.
Therefore, be badly in need of that exploitation one cover is applicable to that current municipal sludge deep dehydration needs with the supporting equipment of sludge modification press filtration drying technique.
