Description
Affiliated field
A kind of garbage loading embeading marsh gas power generation residual heat to dry sludge equipment that the utility model relates to belongs to the environmental protection equipment class.
Background technology
Along with the municipal sewage treatment Facilities Construction progressively raise speed with the sewage centralized treatment rate improve the sharp increase of sludge of sewage treatment plants generation day by day.According to relevant prediction, China's municipal effluent amount also has in next two decades and increases substantially, and quantity of wastewater effluent will reach 440 * 10 in 2010
8m
3/ d; The year two thousand twenty quantity of wastewater effluent reaches 536 * 10
8m
3/ d; Sludge quantity accounts for 0.3%～0.5% (volume) of sewage quantity usually or is about 1%～2% (quality) of sewage load.And if sewage is carried out advanced treatment again, sludge quantity also can increase by 0.5～1 times.At present wastewater treatment in China amount and processing rate not high (4.5%), and annual about 9,000,000 t of mud that discharge in municipal sewage plant, but also with the speed increment in every year about 10%.
A large amount of undressed mud is stacked arbitrarily and discharging has caused new pollution to environment, and its treatment and disposal expense is suitable with the WWT expense usually.Thereby how that output is huge, the mud of complicated component after the science processing, makes its innoxious, resource utilization, and having become China and even whole world environment circle is one of focus of paying close attention to deeply.The traditional sludge treatment of China disposes that initial cost is big, load is low, security requirement is high, problems such as the operational management difficulty is big, service experience shortage, so cause the idleness of equipment, waste is very big.There is great quantity of small sewage work in China, and its mud overwhelming majority fails properly to be disposed, and sludge disposal has become sewage work's design, necessary top-priority important step in service.Sludge treatment is not only China with disposal and is the technological challenge that the world faces.
