Description

Sewage treatment process

Technical field

The invention belongs to technical field of industrial sewage treatment, more particularly, to a kind of sewage treatment process.

Background technology

With the development of industry, water pollution also getting worse, in modern industry, after need to being handled trade effluent The Nature can be discharged into.But traditional sewage disposal system is poor for the Disinfection Effect of processed waste water, so discharge of wastewater or Recycling often will appear the situation for carrying harmful bacterium when using.

Invention content

The present invention is in order to overcome the deficiencies of the prior art and provide a kind of good sewage treatment process of processed waste water water quality.

To achieve these goals, the present invention uses following technical scheme：A kind of sewage treatment process, including following step Suddenly：

（1）Sewage carries out prefiltration processing by grid, removes suspended matter, floating material in sewage；

（2）Sewage is passed through flocculation basin, flocculant is added into flocculation basin, flocculation treatment is carried out to sewage；

（3）Sewage is passed through neutralization pond, neutralizer is added to neutralization pond domestic demand, in neutralization pond neutralization reaction fall the change in sewage Learn ion；Waste water is passed through aerobic tank later, is passed through after reacting 1-2h to inclined-plate clarifying basin excessively；

（4）Sewage flows into sterilization pool, puts into disinfectant, cistern is left to after disinfecting；The disinfectant includes following heavy Measure the component of portion rate：5-6 parts of ethylene glycol stearate, 6-10 parts of citric acid, 4-8 parts of lauryl sodium sulfate are cloudy 9-11 parts of ion or nonionic surfactant, 6-7 parts of Moxifloxacin, 200-250 parts of water.

Further, waste water in reaction process, needs to expose into dissolved oxygen in aerobic tank, and the dissolved oxygen control is in 0.2- 0.5mg/L。

Further, the input amount of the disinfectant is 10-20mg/L.

Further, the dosage of the neutralizer is 10-20kg/L.

Further, the reaction temperature of the neutralization pond is 45-55 DEG C.

Further, the flocculation basin includes pond body, agitating device and driving device；The agitating device includes stirring wheel With the stirring parts on the stirring wheel；The driving device includes the connecting rod being flexibly connected with the stirring wheel, for driving The actuator and traction piece that the dynamic connecting rod moves up and down, when the connecting rod moves up and down, the stirring wheel is along the traction Part scroll-up/down；Stirring wheel is set, is rolled in a longitudinal direction by the stirring wheel, it can be with being located on stirring wheel Stirring parts are rotated, therefore can stir water body, and stirring wheel scroll-up/down, and stirring parts are up and down with stirring wheel, can be incited somebody to action Upper strata flocculant is brought to the lower part of pond body, likewise, driving the suspended particulate of pond body lower floor to upper strata, effectively accelerates flocculant The probability of exposure rate and contact between suspended particulate；Setting connecting rod can position stirring wheel, ensure stirring wheel in rotation It can not carry out left and right displacement；And set actuator can effectively drive link carry out it is up and down, and then connecting rod drive stirring wheel It is up and down；Traction piece cause stirring wheel with connecting rod it is up and down when, stirring wheel can be rolled along traction piece, and one side causes Stirring wheel rotates, and on the other hand stirring wheel is positioned, ensures the stirring wheel remains stationary under non-working condition, and then stirring parts are not Can move so that pond body can be used for part without stirring for water treatment technology, multi-purpose content.

Further, a fixing piece is arranged on the connecting rod, it is removable with the stirring wheel that one is arranged on the fixing piece Unload the bearing part of connection；Fixing piece is set, bearing part can be fixed, so that it is guaranteed that bearing part can not be along the length of connecting rod Direction moves；Likewise, setting bearing part reduces frictional force of the stirring wheel after installing to connecting rod between connecting rod, reduce Mechanical wear prolongs the service life；Stirring wheel is detachably connected with bearing part simultaneously, so as to be convenient for unloading stirring wheel with more Stirring wheel of different size and specifications is changed, can be also convenient for after stirring wheel is unloaded, installing stirring parts on stirring wheel is more convenient.

Further, the fixing piece side wall is equipped with multiple elastic components, which detachably connects with the bearing part It connects；Multiple elastic components being connected with bearing part are set on fixing piece side wall, therefore when connecting rod is up and down, connecting rod can be opposite Small-scale offset occurs for stirring wheel, and can also Rapid reset after offset；The vibrations for avoiding connecting rod up and down and generating It is transferred directly on stirring wheel, ensures the stability that stirring wheel moves on traction piece；Reduce stirring wheel rotation when with traction Abrasion between part improves the service life of device.

In conclusion neutralizer of the present invention can effectively be reacted with sewage, the good neutralization to sewage is realized, ensure Chemical ion in sewage can be neutralized effectively, and then realize the good processing to sewage, good sewage processing effect；And it is discharged The preceding operation that carries out disinfection to waste water effectively avoids the harmful substances such as Carried bacteria in the waste water of water outlet, after further improving processing The water quality of waste water improves later-stage utilization rate.
