Description

The one-stop processing equipment of sludge and technical process
Technical field
The present invention relates to sewage disposal device, a kind of achievable one-stop Treatment of Sludge is particularly related to, realizes that sludge is harmless Change, stabilize, minimizing, sludge can treatment in situ, reduce freight, operating cost is low, the high new dirt of automaticity The one-stop processing equipment of mud.Belong to sludge treatment field, be applicable to Treatment of Sludge.
Background technology
With the constantly improve that the fast development of China's economic construction, urban wastewater treatment firm are built, sewage treatment plant Sludge yield is increased sharply, and the sludge quantity that municipal sewage plant of China is discharged every year is still increased with annual more than 10% speed Long, sludge from wastewater treatment plant is based on biochemical excess sludge, and this kind of moisture percentage in sewage sludge is high, and dehydration property is poor, complicated component, if Serious secondary pollution problem will be caused by dealing with improperly.Therefore, how to handle disposing sludge turns into each Kuomintang-Communist safety economy With the environmental problem faced.
Domestic at present, external common processing method has:Landfill method, burning method, composting process etc..Sludge landfill causes soil The wasting of resources, infiltrates through soil and easily causes secondary environmental pollution.Sludge incineration needs to expend very big energy, and flue gas is also to air Produce pollution.Make into fertilizer but because of sludge complicated, heavy metal component is difficult to degrade.If dealt with improperly, soil will be produced Raw pollution.Its fertilizer efficiency value is not also high.So, all there is drawback in these processing methods.Municipal sludge as townm refuse, its Quantity is extremely huge, and transport is also a big problem present in reality.Sludge will generally transport to the remote place collection of comparison Middle processing, cost of transportation is huge.Water clock in other transportation, the diffusion of peculiar smell also can cause larger to environment Pollution.
From the point of view of existing sludge treatment device, conventional sludge treatment device has:Centrifuge, plate and frame filter press, belt Filter press, folded spiral shell machine etc..Wherein sludge treatment device the most frequently used at present is folded spiral shell machine sludge treatment device, but after its processing Moisture percentage in sewage sludge can only accomplish 80% or so, and the moisture content of national requirements sludge must be reached at less than 60%, ability outward transport Reason.Sludge treatment device in addition to folded spiral shell machine, in real use all in place of Shortcomings.And by the processing of these equipment Sludge afterwards will transport to other factories outside and carry out after-treatment.Can so there is a set of equipment, being capable for the treatment of in situ sludge, reality Existing recycling sludge, innoxious, stabilisation, the one-stop handling process of this sludge of minimizing are exactly the configuration using complete set of equipments, Realize the innoxious of sludge, stabilisation, minimizing, recycling treatment.
At present also there are some sludge treatment devices to achieve preferable effect in certain circumstances, but still suffer from above-mentioned Some problems.In summary, to solve present in prior art, processing sludge ability is weak, cost of transportation is big, easily cause dirt The problems such as dye, need a kind of achievable one-stop Treatment of Sludge of invention badly at present, realize sewage sludge harmlessness, stabilisation, minimizing, it is dirty Mud can treatment in situ, reduce freight, operating cost is low, the automaticity high one-stop processing equipment of new sludge and work Skill process.
