Description
Technical field
The present invention relates to a kind of sludge treating system, relate in particular to a kind of sludge drying system that utilizes the heat supply of the different poly-state energy of sun power.
Background technology
Along with the continuous progress of human society, the two large problems of the environmental pollution of mankind's facing and shortage of resources.According to incompletely statistics, China has built and nearly thousand of the waterworks of building, planning to build and sewage works, the sewage of these waterworkss can produce a large amount of mud after prior art is processed, the volume of mud accounts for 0.5%-10% of sewage volume total amount.These mud bulky, and the pollutent major part of removing in sewage is collected among mud,, if a large amount of mud is not properly disposed, will certainly cause serious secondary pollution.At present, the mode of sludge disposal mainly contains landfill, soil utilization and burning etc.Directly landfill can take a large amount of soils, the polluted underground water of filtrate meeting simultaneously; The soil utilization contains objectionable constituent etc. because moisture percentage in sewage sludge is high, in large, the difficulties in dispersion of traffic capacity, mud former thereby be very restricted; The burning mode as a kind of mode of recycling with the mud energy supply that acts as a fuel, but this processing mode need to be reduced to 30%-40% with the water ratio of mud, otherwise the mud of high-moisture percentage can be low and cause calorific value low because of itself solid content, and then need to expend a large amount of auxiliary fuels, processing cost is obviously higher.Therefore, so far, municipal sludge is carried out drying and other treatment, reduces water ratio is main key issue in present mud subsequent processes.
