Description

A kind of improvement sludge dewatering system
Technical field
This utility model relates to mud and sewage and processes equipment technical field, particularly a kind of improvement sludge dewatering system.
Background technology
Mud produced by sewage disposal has higher water content, due to the characteristic that moisture is combined with mud granule, adopting mechanical means elimination to have certain restriction, the content of organic matter in mud, the addition of ash ratio particularly flocculant are for final solid content important. In general, adopting mechanical dehydration can obtain the solid content of 20%-30%, the mud formed is also referred to as mud cake. The moisture content of mud cake is still higher, has fluid properties, and it disposes difficulty and cost is still higher, it is therefore necessary to decrement further. Now, outside natural air drying, only by inputting heat formation evaporation, extensive decrement can be realized. Adopting the process that heat is dried is exactly heat drying. Common method for sludge treatment is as follows:
(1) natural wind dry method, main units is sludge drying bed, one piece with earth embankment around with separate level land, if the bad hydraulic permeability of soil, rubble and the sand of thin layer can be spread, and set closed drain. Blend evaporation under dependence and reduce the water content banishing the mud on showing up. Infitration process about completed through 2��3 days, and moisture content can be made to be reduced to about 85 percent. Hereafter rely primarily on evaporation, about 75 percent after several weeks, can be dropped to. The dehydrating effect of sludge drying bed, by the impact of local rainfall, evaporation capacity, gas epidemic disaster etc. It is generally applicable in dry, short of rain, the regional employing of sand.
(2) pelletize evaporation, in water, pelletize dewaterer is a kind of new equipment of development. Its main body is the horizontal tubular article that steel plate is made, and is divided into pelletize portion, de-watering section and densification portion, slowly rotates around trunnion axis. Adding the mud after high-molecular coagulant adopting, be introduced into pelletize portion, under the effect of mud self gravitation, flocculation compression, layering is rolled into small muddy pill, and then small muddy pill and water enter de-watering section, and water is discharged from hoop sluicing R-joining. Finally entering densification portion, small muddy pill compresses dehydration further under deadweight, forms the small muddy pill that grain is closely knit greatly, releases cylinder. Comminutor simple structure, not easy to wear, power consumption is few, and maintenance is easily. The moisture content of small muddy pill is typically in about 70 percent. Produced filtrate in the sludge dehydration process of Sewage Plant, except the filtrate contamination content of drying bed less except, other all contain the polluter of high concentration. Therefore these filtrates must process, and is usually and processes together with incoming waste water.
(3) mechanical dehydration method, usual mud first carries out pretreatment, improves dehydration again after dewatering. The most general preprocess method is to add inorganic salt or high-molecular coagulant adopting. Additionally, also have elutriation method and heat treating process. Mechanical dehydration method has filtration and centrifuging. Filtration is to be filtered by wet mud filtering layer (porous material is filter cloth, metal gauze such as), makes moisture (filtrate) ooze filter course, and dewatered sludge (filter cake) is then trapped within filtering layer. Centrifuging is to borrow the produced different tendency to drift aways of solid, liquid difference in specific gravity in mud to reach mud-water separation. The equipment of Filtration has vacuum filter, filter press and band filter. Vacuum filter enters mud, continuous mud extraction continuously, operates steadily, but affiliated facility is more. Filter press is chemical industry common equipment, and filtered driving force is big, and moisture content of the cake is relatively low, enters mud, mud extraction is interval, and productivity ratio is relatively low. Manually-operated filter press, labor intensity is very big, mostly uses machine automatization operation instead. Band filter is novel filter, has multiple design, and the dewatering Principle of foundation also has difference (gravity filtration, pressure filtration, capillary suction, pelletize), but they have rotating belt, transports mud, dehydration on one side, or only fortune mud effect. Their complexity and energy consumption are all close. Centrifuging commonly uses horizontal high-speed sedimentation and centrifugation dewaterer, is made up of interior outer rotaring tube, and rotating cylinder one end is cylindrical, and the other end is conical. Rotating speed is typically in about 3000 revs/min or higher, and interior outer rotaring tube has certain speed difference. Centrifugal dehydrator produces continuously and automatically controls, and sanitary condition is better, takes up an area also little, but the requirement of sludge pretreatment is higher. Mechanical dehydration method is mainly used in primary sedimentation pond mud and digested sludge. The moisture content of dewatered sludge is relevant with sludge quality and dewatering. Generally, the moisture content of the cake that vacuum filters is eight ten ten to percent 6 percent, and filter press is eight ten 40 five to percent percent, and centrifuge dehydration is eight ten five ten to percent 8 percent.
