Description
Technical field
The present invention relates to a kind of environment-protective process more particularly to a kind of processing methods of municipal sewage.
Background technique
For municipal sewage due to complicated component, processing difficulty is larger, and the waste of treated solid or semisolid is still
It so is difficult to handle, present method is landfill, but landfill is at high cost, then how to invent a kind of processing side of municipal sewage
Method both can more perfectly handle sewage, while the waste that sewage treatment generates can be turned waste into wealth, exactly inventor
It solves the problems, such as.
Summary of the invention
The present invention solves above-mentioned problem, and sewage can preferably be handled by providing one kind, and can be by sewage treatment
The sewage treatment process that the waste of generation is turned waste into wealth, specific technical solution are as follows：
A kind of processing method of municipal sewage, includes the following steps：
1. sewage is filtered by fence, then passes to settling pit desilting, sedimentation basin is entered back into；
2. precipitate in water is fallen, upper layer clear water enters next step after flocculant is added in sedimentation basin；
3. by oxidant is added in the water after precipitating；
4. disinfectant is added in water；
5. clear water can be used by obtaining after being filtered by ceramic filter plate；
6. being fabricated to after directly adding the additives such as coal ash powder after the generation filtrate in the above process, sediment are mixed
Building ceramsite.
The clear water of above step production can be used directly as industrial water, and pottery for building is made in filtrate, sediment
Do not have to the problems such as worrying landfill place after grain, cement consumption can be saved instead, turned waste into wealth.
Preferably, the step 1. in fence be followed successively by thick fence, thin fence, metal mesh, lead on the metal mesh
Precipitation by metallic ion and partial organic substances can be electrolysed by electricity with killing small-sized biological such as small fish etc..
The step 2. in flocculant and its application method be：It is by weight percentage by raw material：Polystyrene amide 4
Part, 1 part of polycarbonate, 1 part of aluminium polychloride, 4~8 parts of ferric sulfate, 4~6 parts of iron chloride, 8~10 parts of inorganic salts, active carbon 3
~5 parts, 50~70 parts of bentonite, 3 parts of zinc oxide, 8~10 parts of ethyl alcohol, be heated up to after the mixing of the raw material that 18~22 part of water 50 °~
55 ° of interval ranges, and stirring always one hour, then put into catalyst reaction one hour, by the dry materials, broken after reaction
After broken, sieving, flocculant particle is obtained, then flocculant particle is sprinkled into water.This flocculant is easy to use, and can
To adapt to complicated water condition.
Preferably, the step 3. in oxidant be hydrogen peroxide and ozone.
Preferably, the step 4. in disinfectant be chlorine.
Preferably, the step 5. in ceramic filter plate be ceramic filter plate that capillary aperture is 10~20 microns.
Preferably, the step 6. the specific steps are：By weight percentage, by 30%~60% filtrate, sediment
Product mix mixes aluminium slag powder 3~7%, and industrial flyash 30~50%, desulfurized gypsum 5~10%, white lime is 1~3%, three
The sum of weight percent of 1~3% the above components of ethanol amine is 100%, and various raw material mix in proportion, are then fed into
Ball machine balling-up, then shell adding, at normal temperature, the maintenance of relative humidity 90% or so 5 days or more are finished product to resulting haydite.
The present invention can deal with the water condition of the various complexity in municipal sewage, the industrial water that can be used,
And the waste that sewage treatment generates can be turned waste into wealth, there is good economic value and the value of environmental protection.
