Description
Technical field
The utility model is related to a kind of solid waste treatment device, and category field of solid waste resource utilization field is especially related to
And a kind of device of excess sludge mixture rubbish from cooking methane phase organic fertilizer.
Background technology
Excess sludge is a kind of accessory substance produced during Wastewater Treated by Activated Sludge Process sanitary sewage, and its yield is big, aqueous
Rate is high, and recycling is difficult, and the especially increase of the quickening of urbanization process, per capita water consumption in recent years, sanitary sewage enters
The significantly lifting of field handling rate, makes the yield of excess sludge of municipal sewage plant increase sharply, excess sludge has become
One important sources of municipal solid wastes, are the important components of garbage-surrounded city, different from other solid waste,
Due to containing substantial amounts of organic matter, animals and plants in excess sludge（Microorganism）Residuum, cellulosic, heavy metal etc., if can not obtain
To deal carefully with, ecological environment will certainly be caused to seriously endanger, meanwhile, because containing substantial amounts of moisture, transport in excess sludge
Transfer is very difficult, therefore, and the processing of excess sludge has its unique requirement, it is necessary to which processing nearby is, it is necessary to carry out stabilization as early as possible
Change, it is innoxious, preferably recycling treatment.The method of disposal of typical city domestic sewage excess sludge mainly has recycling
（Such as prepare building materials, roadbed material etc.）, energy（Such as oil-producing, aerogenesis, burning electricity generation, extraction protein）, land use
（Such as compost, soil improvement etc.）, landfill etc..
Rubbish from cooking refers to that resident's daily life and food processing, catering service, unit such as are served the meals at the rubbish produced in activity
Rubbish, including no dish leaf, leftovers, leftovers, pericarp, eggshell, tea grounds, bone etc. are abandoned, its main source is family kitchen, meal
