Municipal sewage (municipal sewage, municipal wastewater) is the dirt entering town sewage system
The general designation of water.Municipal sewage mainly includes sanitary sewage and trade effluent, is typically collected by urban drainage pipe network and is transported to dirt
Water treatment plant processes.Domestic sludge is the regular product of sewage disposal, the mud discharged from sewage disposal, every 100 tons
In containing 80 tons of water, substantial amounts of water is that the subsequent treatment of mud brings numerous difficulties.Mud contains the thalline of a large amount of microorganisms
And organic colloidal matter, cause mud viscosity big.One of the process of mud major issue that always municipal administration faces.
At present, domestic also do not have the technology of maturation to process mud, the most arbitrarily discharge or landfill.Owing to mud containing
Poisonous and harmful substance, this is it is possible to again cause pollution, in some instances it may even be possible to enter human body, and then the body of the harm public by food chain
Body is healthy.Containing substantial amounts of organic matter and nitrogen, phosphorus, potassium in domestic sludge, it is good fertilizer, but harmful owing to wherein containing
Material, limits its recycling, and according to the experience of traditional agriculture, mud can be applied in the soil improving soil on soil
Matter, to promote increasing of crops.It addition, applying sludge can reduce the usage amount of chemical fertilizer and pesticide, thus it is dirty to reduce environment
Dye.Treatment of Sludge is a high energy consumption, the process of high investment, and just because of this, China's municipal sludge can not get effectively for a long time
Process.At present, although the problem of Treatment of Sludge has obtained paying attention to widely, but higher being still of processing cost restricts at whole nation model
The key factor of sludge problem is properly settled in enclosing.Moisture percentage in sewage sludge is difficult to after reaching 80% rely on mechanical dehydration machine to enter again
One step dehydration, common method is that water is removed by the method using heating evaporation.This is that in sludge handling process energy expenditure is
Big link, is also the principal element determining Treatment of Sludge cost.Therefore, the mud dewatering method of development low power consuming, become fall
Low Treatment of Sludge cost is crucial, is also the key technical problem of Treatment of Sludge.
