Description
Technical field
The utility model relates to a kind of combined artificial wetland structure of Processing Paper Wastewater, belongs to sewage treatment area.
Background technology
The composition of paper-making effluent is very complicated, depends on the many factors such as institute's product kind and raw material type.Suspended matter in paper-making industrial waste water is mainly from fiber, filler etc. that the bark of material papering section, careless bits, silt and the ashes discharged with water, slag, each operation of pulping and paper-making run off; In waste water, BOD is mainly derived from pulping and digesting operation, and as carbohydrate, alcohols, organic acid etc. that cellulose decomposition generates, in chemical pulp, the BOD5 generating capacity of cooking waste liquor accounts for more than 80%; COD in waste water and coloring material are mainly derived from lignin and the derivative thereof of pulping and digesting operation; In China, because straw fiber raw material is than great (accounting for 60%), scope of the enterprise is little, and production technique and equipment fall behind, and starting material, the energy, water loss are large, make the pollution of the pulp and paper industry of China especially serious.Paper-making effluent is broadly divided into: pulping and digesting liquid, washes, bleaching effluent and paper machine white water etc.Soda pulp cooking waste liquor, also known as " black liquor ", is the primary pollution source of pulp mill.In the advanced treatment of paper waste, physico-chemical processes has administers fast, high treating effect, and the general method adopted comprises, advanced oxidation processes, flocculent precipitation, membrane separation process absorption method etc.But this kind of technological investment is high, energy consumption is large, working cost is high, thus show technically feasible, irrational feature economically, even if developed country " afford to build, can not turn " also often.
Summary of the invention
The technical problems to be solved in the utility model is: the combined artificial wetland structure providing a kind of Processing Paper Wastewater, solves the deficiencies in the prior art.
The technical solution of the utility model is: a kind of combined artificial wetland structure of Processing Paper Wastewater, mechanical grille pond is communicated with just heavy equalizing tank, air flotation pool, second pond successively and is communicated with primary vertical artificial wetland, then primary vertical artificial wetland is communicated with first-surface artificial wetland, first-surface artificial wetland the other end top is communicated with secondary vertical artificial wetland, secondary vertical artificial wetland is communicated with secondary surface artificial wetland and water collecting basin successively, 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 first-surface artificial wetland and the plantation of secondary surface artificial wetland is water lily, Chinese celery, arrowhead, Herba potamogetonis distincti or lotus.
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 and 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.
Filling soil in first-surface artificial wetland and secondary surface artificial wetland.
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 of one-level, secondary surface artificial wetland: dispose pathogenic micro-organism; The Main Function in primary vertical artificial wetland downstream tank, up pond: mainly dispose; Suspended solids, COD, BOD, colourity, N, P etc., to reduce the processing load of secondary vertical artificial wetland; The Main Function in secondary vertical artificial wetland downstream tank, up pond: dispose fibrous matter, lignin, carbohydrate 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
