Abstract
The invention aims to provide an electro-osmosis sludge dewatering system. According to the technical scheme, the electro-osmosis sludge dewatering system comprises a feed system, a sludge dewatering system and a discharge system. Sludge with 80% water content which is produced from a sludge treatment plant undergoes caching, and the whole set of feed system with sludge caching equipment is assembled at the front end of electro-osmosis equipment. Thus, utilization rate of sludge which enters the dewatering system can be raised effectively. An electro-osmosis sludge dewaterer is adopted as a sludge dewaterer. According to the electro-osmosis sludge dewaterer, dewatering is realized by the phenomenon that sludge particles and water molecules are separated and move in opposite polarity directions. By an extra direct-current electric field and through sludge high-drying dewatering equipment for removing through a certain mechanical pressure a part of interstitial water and absorbed water which cannot be removed by mechanical filter-press in materials, water content of active excess sludge is reduced below 60%. Dewatered sludge is thin mud cakes which are beneficial to later deep drying and natural airing. Thus, aerobic composting or combustion disposal can be carried out.
Description
Technical field
The present invention relates to environmental protection machinery manufacture field, particularly relate to a kind of osmosis sludge dewatering system.
Background technology
Excess sludge (abbreviation mud) is a kind of solid pollutant that municipal sewage plant produces when disposing of sewage, the product after sewage disposal, the heterogeneous body of extremely complexity be made up of organism, inorganic salts, microorganism and parasitic ovum etc.Overwhelming majority municipal sewage plant all adopts Wastewater Treated by Activated Sludge Process sewage.Due to the needs that Microbial Communities in Activated Sludge updates, in sewage treatment process, inevitably produce unnecessary mud, be referred to as excess sludge.The main characteristic of mud is water ratio high (can up to more than 99%), and organic content is high, and easily corruption is smelly, and particle is comparatively thin, and proportion is less, jelly liquid.It is the concentrated thing between liquid and solid, can transport with pump, but it is difficult to carry out solid-liquid separation by sedimentation.So mud is general through processed before going out sewage work.
Owing to containing various pollutent in mud, if do not carry out harmless treatment, disposal, directly render in environment, will to environment.Along with a large amount of construction and the operation of various places sewage work, mud generation increases greatly, and the treatment and disposal of mud has caused the concern of more and more people, and sludge treatment, disposal put on the agenda by many places.Sludge treatment generally adopted simply air-dry or directly sent landfill yard landfill early stage.Because mud is precipitated by active sludge, there is colloidal property, water ratio be 80% mud very large by simply air-dry mummification difficulty of carrying out, needs chronic, generally needs some months.Water ratio be 80% mud can not transport refuse landfill to and carry out landfill disposal.After mud is inserted in refuse landfill, cannot compacting, affect the operation of landfill equipment, and mud may block the percolate guide system bottom landfill yard.Sewage plant sludge is dealt with improperly, will produce a series of harm.Build sludge treatment engineering, resource utilization is carried out to mud, innoxious, stabilization, minimizing process be very necessary.
This osmosis sludge dewatering system is divided into feed system, sludge dewatering system and discharge system.The external world is exposed in order to prevent mud, so collected in mud storage vessel, so also can reduce the pollution to atmospheric environment, and add flocculation agent storage vessel, being also to add organic polymer coargulator in steel basin, being mixed by the drive of stirring driving machine, its effect is improved the dewatering of mud, floc size reduces, and adds organic polymer coargulator mud flco is flocculated again, thus improves dewatering speed.In deposition cache pool, be provided with several buffer subsystem, its effect reduces mud to be stirred the speed of groove institute when releasing, while also can filter out oarse-grained impurity in the middle of mud.Feeding unit adopts screw pump device, mud for 80% water ratio of sewage work's output carries out buffer memory, be assemblied in osmosis front equipment end by this whole set of with the feed system of mud buffer memory device, effectively can improve the mud utilization ratio entering dewatering system.
Sludge dewatering equipment adopts Electroosmosis sludge dewatering equipment, it utilizes mud particle and water molecules mutually to dewater to the phenomenon of contrary polar orientation separate mobile, utilize applying direct current electric field, and the sludge high-drying dehydration equipment of a part of interstitial water that mechanism filter-pressing in material cannot remove and planar water is removed by certain mechanical pressure, the water ratio of active excess sludge is made to drop to less than 60%, and suppose have a back-purge system and service sink, its effect is the blocking material rinsed out in filtrate, and reduces the factor producing head loss; In addition, the pneumatic pump of air compression system is divided into the first compression pump and the second compression pump, when the first compression pump is if there is fault, can open the second compression pump in time to ensure the normal operation of body.In the process of Electroosmosis sludge dewatering equipment work, those can be had very strong oxidisability, higher corrosive medium and mixing acid and carry out neutralization reaction by pickling system, and the environmental protection for waste water is reclaimed very important effect.The mud of water ratio 60% after treatment, dehydrated sludge is thin layer mud cake, is conducive to post depth drying and natural drying, can carries out aerobic compost or burning disposal like this.
