Description
Technical field
The invention belongs to technical field of waste water purification, relate to a kind for the treatment of method of printing and dying wastewater.
Background technology
Textile industry is the pillar industry that China is traditional, including weaving, printing and dyeing, chemical fibre, clothing and textile special equipment system
5 parts such as make.Along with the fast development of national economy, the dyeing industry of China is also into high-speed development period, equipment and technology
Level is obviously improved, and production technology and equipment are constantly updated and regenerated, and the development of printing and dyeing enterprise the most private printing and dyeing enterprise is the most fast
Speed.But, there are certain gap in China's textile printing and dyeing industry technology, facilities and administration level and developed country, the energy of unit product
Consumption, water consumption is relatively big, and such as 1 ton of fabric of China's dyeing and finishing about water consumption 250 tons, and Germany's cotton is spinning is about 100 tons.
Textile industry year displacement about 2,300,000,000 tons, belong to industrial water drainage the 5th, the most mainly dyeing and finishing wastewater, particularly return
By rate less than 10%, for minimum in all industries of national economy, therefore independent research energy-saving and emission-reduction, resource reclaim, waste water advanced
Process and reuse is the most urgent task.From the point of view of enterprise self, dual due to environmental carrying capacity and industrial water
Restrictive function (directly translates into and increases substantially enterprise's water supply, draining quantitative limitation and water supply, charges for disposing pollutants), useless to producing
The advanced treating of water and reuse also have become as enterprise and continue the unique channel of development.Along with developing rapidly of dye industry, combustion
The kind of material and the increase day by day of quantity, the appearance of a large amount of fiber products, adopting of new chemical sizwe, dye material and finishing agent
With, greatly changing the character of dyeing waste water, add its intractability, its COD concentration is also by original hundreds of mg/L
It is raised to 2000～3000mg/L, so that original biological treatment device COD clearance drops to about 50% from 70%, even
Lower.
Commonly used materialization+the biochemical processing process of process of China's dyeing waste water.If it is more multiple that this technique processes water water quality
Miscellaneous, then the COD in water outlet, colourity and salinity are the highest, are directly discharged into water body and can bring potential hazard to environment, also cannot meet
The regeneration requirement of dyeing and printing process.In recent years, increasing producer starts with various types of reverse osmosis membrane processing dress
Put process and the degree of depth reuse carrying out dyeing waste water, except colourity, effectively reduce COD in terms of effect the most satisfied.But reverse osmosis
The investment of permeable membrane processing means is big, and operation cost is higher, and to process in terms of 1 ton of waste water, operation cost needs 5～6 yuan.Existing technology prints
Dye Sewage advanced treatment effect is undesirable, and reverse osmosis membrane processing investment is big, the deficiency that operation cost is high.

Compared with prior art, this treatment method of printing and dying wastewater has the advantage that
1, flocculation basin is by setting up flocculation screen component, in making flocculate be deposited under static open configuration, and leads to
Cross dictyosome to be captured, and the structure of flocculation screen component can effectively prevent flocculate from again spreading, further under rounding state
By periodically drawing in so that high-efficient dirt exhausting, it is to avoid the flocculate of precipitation floats and causes secondary pollution.
2, the processing means of denitrification denitrogenation is divided into two kinds of denitrification denitrogenation states, and one for carrying out in stirring at advection, and two
For carrying out in overflowing precipitation, to optimize denitrification denitrogenation effect, it is achieved high-quality purified treatment.
3, advanced treatment apparatus is by setting up ecological detection cell body, according to the water body requirement after different disposal, profit further
With biology, water body body constitution is sensed to react the purified treatment degree of water body, if degree of purification conformance with standard just derives utilization,
If not meeting just backflow to carry out double purification program, being achieved in repeatedly circular treatment and reaching to purify requirement.
