Description
Technical field
The utility model relates to field of environment protection, particularly a kind of sludge dehydration device.
Background technology
Along with expanding economy, wastewater discharge and sewage treatment facility (sewage work) are increasing.In Sewage Plant, the processing that is accompanied by sewage can produce 0.5～2% mud, and sludge treatment disposal and method become the focus of domestic and international concern gradually.Show that according to firmly building portion's data by the end of the end of the year in 2009, national town sewage treatment capacity reached for 280 billion cubic meter/years, wet mud (water ratio 80%) generation is broken through 2,000 ten thousand tons/year.And in sewage treatment process, bacterium and most of Parasites are deposited in the mud, and virus also can be adsorbed on the particle in the sewage, also deposit in the mud with the particulate deposition.Mud is a kind of by product of Pollution abatement technology; This by product enrichment pollutants in sewage; Contain hazardous and noxious substances such as nutritive substances such as a large amount of nitrogen, phosphorus and organism, viral micro-organisms, parasitic ovum, heavy metal, have stronger pollution character.If mud is mishandling, the approach of its pollution spread is very widely.At first, the water ratio of mud is high, and except a part of spontaneous evaporation is in air, major part will be infiltrated surface soil layer, and under the washing away of rainwater etc. entering surface water system or influence underground water, the pollutent in the mud will be propagated along these two kinds of approach.Secondly, the mud that does not carry out sanitisation gets into the farmland down to the vegetable plot, the possible direct threats mankind's food chain.The 3rd, mud contains a large amount of organic matters, and is easily corrupt and distribute stench, possibly influence surrounding enviroment.And the gas of discharging is with serious pollution greenhouse gases, and environment is produced serious harm.In addition, the quantity of mud is huge, and these mud of accumulating need bigger space and a lot of instruments, and these spaces and instrument all maybe be contaminated, accomplish to acquire a certain degree of difficulty with world's effective " completely cutting off " of other contacting foodstuff chain.Obviously,, get into human food chain, will inevitably cause transmission of disease if mud is mishandling.
Yet in the WWT development course, although mud is one of important step in the WWT flow process, because secular insufficient recognition of people and ignorance, the sludge disposal problem is shelved for a long time, and the development of sludge disposal quite lags behind.Show that according to finding the mud that China municipal sewage plant is produced has 80% not dealt carefully with, the mud generation greatly, is arbitrarily stacked and the pollution and the recontaminate problem that are caused have highlighted, and has caused social concern.
Sludge treatment and method of disposal commonly used are now seen Fig. 1.
