Abstract
The utility model discloses a kind of combined artificial wetland structure processing hospital sewage, it is characterized in that: mechanical grille pond (1) is communicated with equalizing tank (2) successively, primary sedimentation pond (3), sterilization pool (4) and first-surface artificial wetland (5), first-surface artificial wetland (5) top is communicated with primary vertical artificial wetland (13), then secondary sedimentation basins (8) is communicated with, secondary sedimentation basins (8) the other end top is communicated with secondary vertical artificial wetland (14), secondary vertical artificial wetland (14) is communicated with secondary surface artificial wetland (11) and water collecting basin (12) successively, all purifying plant is planted in each artificial swamp pond.
Description
Technical field
The utility model relates to a kind of combined artificial wetland structure processing hospital sewage, belongs to field of environmental improvement.
Background technology
In recent years, Hospital Sewage Treatment causes the attention of various circles of society gradually, owing to usually containing the medical science rubbish such as various medicine, chemical substance, radioactive substance in hospital sewage, simultaneously also containing a large amount of virus, bacterium, parasitic ovum and other objectionable impuritiess, badly very easily cause serious pollution once process.
Now for Hospital Sewage Treatment primarily of two classes: (one) only adopts contact sterilizing process to the hospital sewage entering municipal sewage system (being provided with secondary urban wastewater treatment firm); (2) biochemical treatment+sterilization process is adopted to the hospital sewage entering natural water, sewage is removed after bulk solid foreign material through grid and is entered hydrolyzing regulation pond, a large amount of aerobic-anaerobic microbes is filled with in pond, microorganism can by the insoluble rejection to organics hydrolysis in sewage, decompose larger molecular organics simultaneously, for the process of aerobic operation creates favorable conditions, regularly pass into air in pond and stir, to increase the sludge activity that carries disease germs.Then only carrying out disinfection with biochemical treatment for hospital sewage in prior art is not thoroughly.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of combined artificial wetland structure processing hospital sewage, to process hospital sewage more thoroughly.
The technical solution of the utility model is: a kind of combined artificial wetland structure processing hospital sewage, mechanical grille pond is communicated with equalizing tank, primary sedimentation pond, sterilization pool and first-surface artificial wetland successively, first-surface artificial wetland top is communicated with primary vertical artificial wetland, then secondary sedimentation basins is communicated with, secondary sedimentation basins 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, Herba Limnophilae Aromaticae, duckweed, large najas marina 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 disinfection by ultraviolet light.
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 disposes pathogenic microbes; The Main Function in primary vertical artificial wetland downstream tank, up pond: dispose suspended solids, COD, BOD etc., to reduce the processing load of secondary vertical artificial wetland; The Main Function in secondary vertical artificial wetland downstream tank, up pond: dispose acid, alkali, N, P 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.
