Description
Technical field
The present invention relates to environmental technology fields, and in particular to a kind of sewage water treatment method.
Background technology
Sewage disposal is to make the mistake that sewage reaches a certain water body of draining or the water quality requirement that reuses purifies it
Journey.It is each that sewage disposal is widely used in building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment, food and drink etc.
The daily life of common people is also come into field more and more.
Classify by sewage source, sewage disposal is generally divided into production sewage treatment and sanitary sewage disposal.Production waste packet
Trade effluent, rural sewage and medical sewage etc. are included, and sanitary sewage is exactly the sewage that daily life generates, and refers to various shapes
The inorganic matter of formula and the complex mixture of organic matter, including:1. floating and the size solid particle to suspend;2. gluey and gel
Diffusate;3. pure solution.Divide by the matter of water dirt, the pollution of water there are two classes:One kind is natural pollution;Another kind of is artificial dirt
Dye, currently larger to water body harm is artificial pollution.Water pollution can be broadly divided into chemically according to the difference of pollution impurity
Pollution, physical pollution and biologic contamination three categories.Pollutant mainly has：(1) unprocessed and discharge industrial wastewater；⑵
Unprocessed and discharge sanitary sewage；(3) the farmland sewage of chemical fertilizer, pesticide, herbicide is largely used；(4) stack by the river
Trade waste and house refuse；(5) soil erosion；(6) mine system engineering.There are many method of treated sewage, can generally be summarized as object
Logos, chemical method and bioanalysis etc..
At present, it is collective conveyance between Treatment of Sludge for sludge caused by the stage each in sewage disposal process,
Concentration carries out sludge dehydration compression, then sludge dewatering is returned to primary sedimentation tank and carries out sewage disposal again, this method
It can be containing the medicament added in some sewage disposal process or with some bio-film colonizations, in this way in the sludge dewatering of middle return
The processing load of primary sedimentation tank can be increased, it would be highly desirable to improve.

4th, the sewage after primary sedimentation tank processing is admitted to electrolytic cell, and sewage microelectrolysis processing is carried out in electrolytic cell, realizes
Light electrolysis pre-oxidation is biochemical again, and electrolysate is dense into its corresponding sludge concentration device progress by the sludge-discharge pipe of its underpart
Contracting, the sewage after electrolysis continue to be fed into contact-oxidation pool and continue to react；
5th, the sewage after electrolytic cell processing is admitted to contact-oxidation pool, sewage in catalytic oxidation with microorganism fungus kind or
Person's oxidant catalytic oxidation, the part heavier solid object of generation by sludge-discharge pipe are sent into its corresponding sludge after precipitating
Sludge condensation is carried out in concentrator, concentrate is delivered in contact-oxidation pool again, while by thickened sludge by always arranging
Sludge pipe is delivered between Treatment of Sludge；
6th, by contact-oxidation pool processing after sewage be admitted to secondary settling tank, sewage precipitates in secondary settling tank, precipitating sludge by
Sludge-discharge pipe is sent into its corresponding sludge concentration device and carries out sludge condensation, concentrate is delivered in secondary settling tank again, together
When thickened sludge is delivered to by total sludge-discharge pipe road between Treatment of Sludge；
7th, between Treatment of Sludge to convey into process predrainage treated that sludge carries out that discharge is concentrated in recompression.
After above-mentioned technique, the present invention has the beneficial effect that：A kind of sewage water treatment method of the present invention, can be in dirt
The sludge that each stage of water process generates it carries out sludge dewatering treatment, and dehydration is delivered to corresponding place again
Reason is reprocessed in pond, mitigates the processing load between sludge, while also reduces processing load of the primary sedimentation tank for the sewage that flows back,
Practicability is stronger, and the present invention has the advantages that simple in structure, setting is reasonable, low manufacture cost.
