Description
Technical field
The invention belongs to sewage treatment project technical field, and in particular to a kind of utilization side to sludge in sewage treatment plant
Method.
Background technology
Sludge is the product after sewage disposal, is that one kind is made of organic debris, microorganism, inorganic particle, colloid etc.
Extremely complex heterogeneous body.The key property of sludge is moisture content height（Up to more than 99%）, high organic content, holds
Easily degenerate smelly, and particle is thinner, and proportion is smaller, jelly liquid.It is the concentrated thing between liquid and solid, can
To be transported with pump, but it is difficult to carry out separation of solid and liquid by settling.The component of sludge includes protein, lipid, urea, fiber
Element, nitrogen phosphorus, metal oxide, heavy metal and mineral matter etc..
There is scholar the 1960s to ensure that sludge treatment proposes safely a kind of i.e. sludge sanitary landfills of technological means.
Nowadays, sludge Sanitary Landfill Technology has tended to be ripe, is widely applied in practice.Although Sludge landfill is required basic
Threshold is low so that and the cost of sludge treatment is low, quick, method is simple etc., but in this process, Sludge landfill technology
Shortcoming is also gradually exposed.For example, erosion and other extraneous factors due to rainwater, the poisonous and harmful substance in sludge occurs
The leakage meeting gas such as polluted underground water environment, the methane of release is easy to set off an explosion and burn.Sludge landfill can produce largely
Methane gas, and methane gas produces atmospheric warming tremendous influence as greenhouse gases, or even can serious destruction ozone
Layer.
