Put.
Background technology
The effluent of printing and dyeing enterprise institute has big water, organic pollution content height, difficult degradation, colourity depth, alkaline big, water quality
The features such as change variation, thus belong to industrial wastewater difficult to deal with.At present, the conventional treatment of dyeing wastewater work of dyeing
Skill, is broadly divided into two major classes, physico-chemical process and biochemical process.As country improves constantly the requirement for discharging water quality, seek more to increase
Effect, economic, stable advanced treatment process turn into environmental protection industry (epi) problem of interest instantly gradually.
Various deep treatment methods more popular at present have：BAF, advanced oxidation processes（Fenton process）, physics inhale
Attached method, UF membrane counting method etc..But, often there is poor technology stability, operating cost height in practice operation production, produce
Secondary pollution and the problem of increase post-processing difficulty etc..
The content of the invention
The present invention in order to overcome the deficiencies in the prior art there is provided a kind of high treating effect, operating cost it is low be used for print and dye
The advanced treatment apparatus of waste water.
To achieve these goals, the present invention uses following technical scheme：A kind of advanced treating for dyeing waste water is filled
Put, including fibre turntable filter chamber, ozone contact tank, filter tank, reaction tank, sedimentation basin and the cistern being sequentially connected, the ozone
Contact chamber connects an ozone preparing device, and the ozone preparing device connects an oxygen preparing device；On the ozone contact tank and filter tank
Provided with tail gas breaking plant；3 extension boards are intervally distributed with the ozone contact tank, the extension board lower end is fixed on the ozone
Pool wall under contact chamber, the first pond body, the second pond body and the 3rd pond body are divided into by the ozone contact tank, first pond body,
Second pond body and the 3rd pond body bottom are respectively equipped with an aerator, and the aerator is connected with the ozone preparing device；It is described
Powdered Activated Carbon is connected with upper active charcoal, the reaction tank add pipe and flocculant concentration pipe in filter tank；Described first
A water fender is respectively equipped with pond body, the second pond body and the 3rd pond body, the water fender upper end is fixed on the ozone contact tank
Pool wall, water fender lower end extends to extension board middle and lower part position；Mud part is scraped provided with one in the sedimentation basin, this scrapes mud portion
Part includes cleaning shoe and actuator；The cleaning shoe is provided with the abrasionproof for reducing its frictional force between sedimentation basin bottom surface
Damage structure.The present invention integrates the kinds of processes such as filtering, oxidation, absorption, flocculation, and obvious processing effect is stable, wastewater effluent
Colourity is below 4 times, and waste water COD and suspension are relatively low, and water treatment efficiency is good, and one-level B discharges are can reach after wastewater treatment
It is required that, realize environment protection emission；Ozone contact tank is separated into 3 pond bodies so that ozone realizes that segmentation is added, and catalytic efficiency is more
Height, realizes good COD removal effects, and ozone supply amount keeps constant, cost-effective；Pass through Powdered Activated Carbon and flocculant
Synergy, realizes good flocculating effect, effectively removes the suspension in waste water, effectively improves effluent quality, technological operation
Simply, operating cost is low；Because water fender extends to the middle and lower part position of extension board, so that ozone contact tank can not water
Advection is logical to be flowed, it is necessary to bypass water fender, thus increase degree increase that waste water stops in ozone contact tank when
Between, the contact with ozone is more abundant, and oxidation reaction is more preferable；There is provided anti-wear structure, can effectively reduce cleaning shoe and precipitation
