Abstract
The utility model discloses a kind of composite vertical current artificial wetland structure for the treatment of of dyeing and printing, it is characterized in that: mechanical grille pond (1) is communicated with aerating regulation pond (2) successively, first coagulative precipitation tank (3), sterilization pool (4) and primary vertical artificial wetland (11), primary vertical artificial wetland (11) bottom is communicated with secondary sedimentation basins (7), secondary sedimentation basins (7) the other end top is communicated with secondary vertical artificial wetland (12), secondary vertical artificial wetland (12) connected set pond (10), all purifying plant is planted in each artificial swamp pond.
Description
Technical field
The utility model relates to a kind of composite vertical current artificial wetland structure for the treatment of of dyeing and printing, belongs to sewage treatment area.
Background technology
Along with the fast development of economy and dyeing, the quantity discharged of dyeing waste water also constantly increases.About there is the dyestuff of 10% ~ 15% to enter environment with waste water according to statistics in production and use procedure, make dyeing waste water account for 60% ~ 80% of comprehensive draining amount.Dyeing and finishing industry dyestuff majority used is synthetic dyestuff, add adding of some New-type adjuvants, PVA slurry etc., dyeing waste water is had colourity is large, COD change greatly, organic components is complicated and concentration is high, alkalescence greatly, the feature such as biodegradability is poor, toxic, water quality and quantity changes greatly, therefore become one of the most unmanageable generally acknowledged waste water.Acidication technique is widely used in various sewage treatment project, as the wastewater treatment process of the industries such as printing and dyeing, chemical industry, papermaking, pharmacy as the pre-treating technology of anaerobic and aerobic treatment process.Acidication technique is owing to having certain clearance to hardly degraded organic substance, COD, colourity etc., and macromolecular substance can be degraded to small-molecule substance, thus improve the biodegradability of waste water, therefore, using acidication as independently biological treatment and a kind of effective preprocessing means, strengthened and improved, be widely used in treatment of dyeing wastewater, and achieve certain effect, but it is not thorough to dispose of sewage.
Summary of the invention
The technical problems to be solved in the utility model is: the composite vertical current artificial wetland structure providing a kind for the treatment of of dyeing and printing, solves the deficiencies in the prior art.
The technical solution of the utility model is: a kind of composite vertical current artificial wetland structure for the treatment of of dyeing and printing, mechanical grille pond is communicated with aerating regulation pond, first coagulative precipitation tank, sterilization pool and primary vertical artificial wetland successively, primary vertical artificial wetland bottom is communicated with secondary sedimentation basins, secondary sedimentation basins the other end top is communicated with secondary vertical artificial wetland, secondary vertical artificial wetland connected set pond, all plants purifying plant in each artificial swamp pond.
In mechanical grille pond, sewage approach axis sets gradually the coarse rack of 20 ㎜ and the fine fack of 5 ㎜.
Primary vertical artificial wetland comprises primary vertical artificial wetland downstream tank and the up pond of primary vertical artificial wetland.
Secondary vertical artificial wetland comprises secondary vertical artificial wetland downstream tank and the up pond of secondary vertical artificial wetland.
The purifying plant of primary vertical artificial wetland and the plantation of secondary vertical artificial wetland is giantreed, cyperus alternifolius, spot thatch, Fructus Sapindi Mukouossi or Spiked Loosestrife.
Water collecting basin adopts ultraviolet, ozonization.
Add gravel bed, coarse sands layer successively from the bottom to top in primary vertical artificial wetland, wherein coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm.
Add gravel bed, coarse sands layer and fine sand layer successively from the bottom to top in secondary vertical artificial wetland, wherein fine sand particle diameter is 0.2-0.4cm, and coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm.
Primary vertical artificial wetland downstream tank and secondary vertical artificial wetland downstream tank top layout water distributor.
The beneficial effects of the utility model: the Main Function in primary vertical artificial wetland downstream tank, up pond: dispose SS, COD, BOD colourity etc., to reduce the processing load of secondary vertical artificial wetland; The Main Function in secondary vertical artificial wetland downstream tank, up pond: dispose N, P, heavy metal etc.; For ensureing that wet land system water distribution is even, each piecemeal wetland is provided with independently water distribution system, adopts staged water distribution manner.
