Description
Technical field
The invention belongs to technical field of sewage, more particularly, to a kind of settlement of sewage pretreatment system and method.
Background technology
Daily, industrial production etc. often produces substantial amounts of waste water, and these waste water can not be directly discharged into natural water source, must
It must could be discharged after wastewater treatment.Existing dyeing waste water is carried out in processing generally by the way of coagulation-precipitation
Processing, carries out coagulation formation little particle, so as to be precipitated in sedimentation basin, to go by coagulation by the material caused in waste water
Except some in waste water can not be discharged into the material into natural water source.But, under this kind of processing mode, it can only get rid of in waste water
Some the tiny suspended materials and colloidal substance existed, enter in the waste water of biochemistry pool after precipitation process still containing a large amount of
Hard-degraded substance extends whole processing procedure, it is necessary to carrying out prolonged oxidative degradation in biochemistry pool can be removed
Time-consuming, operating efficiency is low；And some materials for being difficult to degrade remain unchanged and can not be degraded, and are finally discharged into natural water source,
Cause water pollution.
The sludge that is precipitated in preliminary sedimentation tank needs to carry out scraping mud processing by scraping mud part, but existing scrapes in mud part
Cleaning shoe be typically directly in contact with the bottom surface of sedimentation basin, greatly, the abrasion of cleaning shoe is extremely tight for frictional force between the two
Weight, service life is short.
The content of the invention
There is provided a kind of a kind of sewage simple in construction, service life length is heavy in order to overcome the deficiencies in the prior art by the present invention
Shallow lake pretreatment system and method.
To achieve these goals, the present invention uses following technical scheme：A kind of settlement of sewage pretreatment system, including
Interconnected equalization pond, regulating reservoir, coagulating basin, distribution well, preliminary sedimentation tank and biochemistry pool, the equalization pond connection one is intake
Pipe, the biochemistry pool connects an outlet pipe；The coagulating basin be connected with ferrous sulfate locker room, for by ferrous sulfate by sulfuric acid
Ferrous locker room adds to the ferrous sulfate of coagulating basin and adds pump, sulfuric acid locker room, for sulfuric acid to be added by sulfuric acid locker room
Sulfuric acid to coagulating basin adds pump, hydrogen peroxide locker room and for hydrogen peroxide to be added to coagulation by hydrogen peroxide locker room
The hydrogen peroxide in pond adds pump；The distribution well is connected with sodium hydroxide locker room and polyacrylamide locker room；It is described just heavy
Pond includes pond body, the discharge pipeline scraped mud part and be communicated in pond body sidepiece being placed in pond body；The mud part of scraping includes being located at
Cleaning shoe on sedimentation basin bottom surface, the drive link being connected with the cleaning shoe, the drive shaft being connected with the drive link and for driving
The actuator of the drive shaft turns；The cleaning shoe is provided with the abrasionproof for reducing its frictional force between sedimentation basin bottom surface
Damage structure, the anti-wear structure includes being spaced apart in multiple anti-wear components on the cleaning shoe；The anti-wear component
Including ball the opening that the positioning sleeve is passed for ball is provided with the positioning sleeve outside the ball, the positioning sleeve is covered at；
The positioning sleeve is detachably connected by a disassembly and assembly structure and institute cleaning shoe.The present invention on coagulating basin by directly connecting all kinds of
Medicament locker room, to add medicament into coagulating basin so that Fenton's reaction occurs in coagulating basin for medicament so that coagulating basin can be
The processing pre-oxidized on the basis of coagulation to waste water, so that slightly modified i.e. available on traditional Waste Water Treatment
The effect of oxidation processes, without building a set of processing system containing Fenton pond in addition, the construction period is short, and construction cost is low；And
Sewage is pre-processed by fenton methods, macromolecular hard-degraded substance can be decomposed into small-molecule substance, high degree
Raising waste water biodegradability, improve subsequent biochemical treatment effeciency；And sodium hydroxide and polypropylene have been added in distribution well
Acid amides, accelerates the flocculation of suspended material and colloidal substance, and then increases its sinking speed and efficiency in preliminary sedimentation tank；Set
Anti-wear structure, can effectively reduce the abrasion between cleaning shoe and sedimentation basin bottom surface, the service life of extension device；Positioning sleeve
Upper to be provided with opening, when positioning sleeve is locked on cleaning shoe, the bottom of ball can be passed by the opening to positioning sleeve
Lower surface, cleaning shoe is lifted off to the bottom surface of sedimentation basin；When being placed in sedimentation basin bottom so as to cleaning shoe, be ball with sedimentation basin bottom it
Between come in contact, cleaning shoe one end carry out scrape mud during, ball can be rolled freely, and cleaning shoe will not be ground
Damage, abrasion is occurred over just on ball, only need periodically to change ball, without being changed to cleaning shoe, reduction dimension
Accomplish this；And ball can relative positioning set carry out 360 ° of rotation, stuck phenomenon, equipment operation will not occur during motion
