Description
Technical field
The present invention relates to technical field of sewage, more specifically, it is related to a kind of sewage disposal system.
Background technique
With the development of economy with the propulsion of urbanization process, the discharge amount of trade effluent and sanitary sewage also passs year by year
Increase, the enterprise on general city inland river road periphery is numerous, there are the serious pollutions industry such as Leather Factory, used oil processing factory, electroplate factory point
Cloth, these enterprises are substantially heavily contaminated enterprise, such as leather waste water, and there is water quality and quantity to fluctuate big, concentration of suspension
Height, easily corruption, generation contaminant capacity is big, the toxic compounds such as waste water Nitrogen-and Phosphorus-containing, sulfide and cadmium.And the greasy dirt leakage of used oil factory
Also very serious to the pollution of water body, substantially every 1L machine oil can be 100000 square metres of polluted-water area, cause the envelope of water body
Anoxic is closed, and the natural degradation period of greasy dirt is very long；Electroplating wastewater not only has soda acid variation, but also administers and be not thorough meeting
It is polluted containing cyanide, ammonium hydroxide, salicylic acid, heavy metal etc..The pollution of these high COD, ammonia nitrogen, sulfide, heavy metals etc., not only
The direct polluted-water of meeting, and since these pollutants much all have biological toxicity, fundamentally destroy the life of water body
State balance.And the sanitary sewage of neighbouring resident is not in place due to comprehensive sanitary sewage pipe network, and domestic pollution can be also drained into
In interior river, so also it is serious influence water body self-purification capacity.
Existing sewage disposal system is varied, mainly has chemical method, biological method and physico-chemical process etc. dirty
Water treatment system can refer to the Chinese invention patent application file that application publication number is CN1412133A in the prior art, public
A kind of air stirring, sludge-refluxing chemical flocculation precipitation sewage treatment method, treatment process are as follows: returned sludge and sewage are opened
Flocculation tank is first flowed into, chemical floc is continuously added in flocculation tank: aluminium polychloride, ferric trichloride；Add height
Molecule flocculation aid PAM, and aeration oxygen supply and stirring are provided by air diffuser system, make the suspended solid in returned sludge and sewage
Reach bioactivation, form bioflocculation and a degree of biological oxidation；Flocculation reaction is mixed by air, it is heavy to be formed
Activated sludge wadding body, chemical wadding body and metal phosphate chemical precipitates of good performance drop, and sewage is in flocculation tank stop
Time is 10~30 minutes, is then introduced into sedimentation basin, completes to be separated by solid-liquid separation in sedimentation basin；Activated sludge and chemistry after precipitating
The discharge of wadding body autoprecipitation bottom of pond portion outlet, and pass through mud return line system flowback into flocculation tank to keep reaction tank
Sludge concentration, return sludge ratio adjusts in 10%~50% range according to actual needs, and partial sludge is as excess sludge
It is discharged from processing system；The clarification and effluent of sedimentation basin is the discharge water of processing system.
The flocculating effect of chemical floc is poor in existing this sewage water treatment method and flocculation time is longer, for dirt
Removal effect in water is poor.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of sewage disposal system, wherein using

Solidifying agent, the diatom and concentration for being mainly 70% by concentration are the ratio that 40% polymerization oxidation iron is 80-90:10-20 in mass ratio
Compounding is made respectively.
By embodiment 1-5 and comparative example 1-3 be made in flocculant be applied to following simulated water sample processing:
(1) prepared by simulated water sample: weighing 7 parts of 0.3g kaolin and is added separately in 1000mL tap water, stirs evenly, prepare
7 parts of simulated water samples；
(2) test method: the measurement initial haze (A) of 7 parts of simulated water samples of test is put into identical respectively into 7 parts of simulated water samples
Flocculant made from the embodiment 1-5 and comparative example 1-3 of quality stirs 5min with the mixing speed of 300r/min, then with 50r/
The mixing speed of min stirs 15min, and different time points after agitation take the test turbidity (B) of simulated water sample, turbidity removal rate
The turbidity removal rate and removal time test of flocculant made from=(A-B)/A × 100%, embodiment 1-5 and comparative example 1-3
As a result it is shown in table 2.
The turbidity removal rate and removal time test result of flocculant made from table 2 embodiment 1-5 and comparative example 1-3
As can be seen from Table 2, flocculant made from flocculant and comparative example 1-3 used in 1-5 of the embodiment of the present invention is stirring
When identical time point is tested afterwards, the turbidity removal rate of flocculant made from embodiment 1-5 is being higher than made from comparative example
Flocculant, and flocculant made from embodiment 1-5 is rapid-action, action time is short, and in 20min, turbidity removal rate be can reach
Absolutely.
According to water environment quality standard (GB3838-2002) to by wadding a quilt with cotton made from embodiment 1-5 and comparative example 1-3
Treated that simulated water sample is detected for solidifying agent, and testing result is shown in table 3.
The performance test results of flocculant made from table 3 embodiment 1-5 and comparative example 1-3
As can be seen from Table 3, the indices of the water after the flocculation of flocculant made from embodiment 1-5 meet surface water environment quality
Standard (GB3838-2002) is to requirement more than V class water or V class water quality, and the water after the flocculation of flocculant made from comparative example 1-3
Indices not as good as embodiment 1-5 be made flocculant.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
