The primary process of system handles polluted river water of the present invention is: (1) filler-reinforced biological treatment system 2,3, and (2) haydite reed bed advanced treatment system 4,5, and (3) wetland landscape 6 stores 3 stages formations such as utilization.
(1) filler-reinforced biological treatment system 2,3: the polluted river water that downstream area extracts in the river course; Carry by sewage water inlet pipe 1 through the simple pre-treatment of lateral sulcus (deposition clarification); At first carrying out pollutent at filler-reinforced biological treatment stage (2,3) cuts down; Purifying main body mainly is the self-sown bacterium algae film that Ball-type packing 11 adheres to, and purpose is to strengthen damming and biological degradation of pollution of estuary thing; Filling ratio difference by required filler is divided into two-stage; First step filler clean-up bed 2 filling ratios are higher relatively; Mainly hold back most suspended substances and considerable part organic pollutant, also can remove nutritive substances such as part N, P through biomembranous Degradation through the physical structure of filler and the biomembranous filtering function that adheres to; For causing microbial film, the reduction that prevents pollution load causes the generation that comes off significantly owing to microorganism growth is limited; And consider the factors such as activity space of aquatic animals and plants; Second stage filler clean-up bed 3 filling ratios are relatively low; With nutrition such as further reduction organic pollutant and N, P, thereby suppress algae grows speed; The total hrt of filler-reinforced biological treatment is 5.0 hours, depth of water 30cm; Above-mentioned filler clean-up bed summer operation 10 ~ 15 days; Filling surface can form the bacterium algae film of 0.2 ~ 0.5cm thickness; Occur the filtering layer that is made up of the microbial film that comes off and large-scale silkweed class, moss etc. in the system, formation comprises the metastable aquatic ecosystem of hydrocoles groups such as water flea, snail in the water body;
(2) haydite reed bed advanced treatment system 4,5: the main body of said haydite reed bed advanced treatment system is the combined filtration bed that haydite and reed form; Purpose is the alga cells of filter packing bed water outlet and the bacterium algae film that comes off, further cuts down pollutent through a series of scrubbing approach of haydite reed composite system simultaneously; The water outlet of filler-reinforced biological treatment system 2,3 generally contains nutritive substances such as the more relatively algae of quantity and partial organic substances and N, P; The absorption of the Degradation of materialization absorption and the attached biological film thereof of this stage through haydite surface, reed root system physical structure hold back and the allelopathy (is major function to remove algae) of metabolic substd together with the Degradation of its attached microbial, the long period absorbing enriched effect of plant and a series of complicated approach such as synergistic purification effect of plant-haydite; Pollutent is further cut down; Main P pollutant (TP, the PO43-P etc.) load of cutting down, algae is removed basically; The hydraulic load 1.8m of haydite reed bed advanced treatment
3/ m
2D, depth of water 30cm; Above-mentioned haydite reed bed adopts the mode of two groups of haydite reed beds parallel connection to move, and it is relatively low and cause treatment scale limited mainly to solve hydraulic load, and head loss is relatively large and cause the excessive problem of facility gradient;
(3) wetland landscape 6 stores utilization: the water outlet of haydite reed bed advanced treatment gets into landscape wetland and stores; Air reaeration process through the drop reinforcement; Store water body DO content and remain on higher relatively level; The serial process that can impel the aquatic ecosystem material to transform is progressively perfect, makes the pollutent in the water body be in low-level relatively material conversion equilibrium state, realizes that the long period that stores water quality keeps; Said wetland landscape 6 is strengthened the air reaeration function through drop; Make and store water body DO content and keep relative higher level; Impel the aquatic ecosystem material to transform the progressively perfect of serial process; Water pollutant is in low-level relatively material and transforms equilibrium state, realizes the maintenance of long period water quality; According to the waterpower scheduling requirement that unhurried current river course lateral sulcus refluxes, view rising pipe 7 enters the upper reaches of unhurried current river course main stem 8, through water flows property that strengthens main stem 8 and the dual functions such as water quality dilution of strengthening the water outlet of lateral sulcus system, improves the water quality in unhurried current river course 8; The waterplant area coverage accounts for 35% of water surface area in the above-mentioned landscape wetland, and the fountain active area accounts for 56.25% of water surface area.Store the water level 0.5 ~ 1.0m of water body, DO is not less than 4.0mg/L.
The practical implementation of unhurried current of the present invention river course lateral sulcus renovation technique comprises that process flowing line makes up and water flowing operation two portions.Process flowing line makes up and is divided into construction such as pre-treatment facility, main body facility, low-lying land.The river pre-treatment is accomplished through natural processes such as sedimentation clarifications in the river course lateral sulcus, constructs the lateral sulcus canal on unhurried current bank, river course or suitable zone, and as the simple pre-treatment facility of this technology, the irrigation canals and ditches end has the water intaking pond, makes river flow into the water lift pond naturally through run by gravity; Filler clean-up bed 2,3 is realized through constructing the rectangle pond; In the pond according to the requirement of filling ratio; Filling Ball-type packing 11, the buckle in that the pool inner wall symmetry leaves fixes filler 11 in order to braided wires netting 10; According to the hydraulic detention time requirement of filler-reinforced biological treatment, with 2,3 series operations of two cover filler clean-up beds; Haydite reed bed 4,5 is also realized through the pond; After in the pond, loading haydite 17 matrix on request; Re-lay aggregate chips layer 15 in the above,, select wild reed 14 for use in order to support plant; To the practical problems of haydite reed bed 4,5 system handles dimension-limited that hydraulic load is little and head loss causes greatly and increase laid down cost, with 4,5 parallel runnings of two cover haydite reed beds; Landscape wetland is to realize through the transformation to the low-lying land zone; Require at first low-lying land to be carried out the preliminary transformation of aspects such as bed mud dredging, expansion waterplant scale according to landscape construction; So that can form the natural water area of the depth of water 0.5 ~ 1.0m after the water flowing, waterplant coverage 35%, and according to the requirement of view structure; Divide the fountain zone in the corresponding position in low-lying land waters, the fountain zone total area is not less than 56.25% of the water surface.According to the extension film needs of filler 11 and the different border growth adaptability requirement of plant, first low discharge water inlet is taked in water flowing operation, treats that carrier biofilm hangs after film maturation and plant-growth shake down basically, again the sequence mode of augmented flow gradually.The water outlet of river after bed of packings 2,3, haydite reed bed 4,5 are handled;, run by gravity stores in getting into landscape wetland; And the waterpower scheduling requirement that refluxes according to unhurried current river course lateral sulcus; Enter the upper reaches of unhurried current river course main stem 8,, reach the purpose of improving unhurried current river course main stem 8 water quality through strengthening main stem 8 water flows property and strengthening the dual functions such as water quality dilution of lateral sulcus system water outlet.
Net effect of the present invention is good; Polluted river water through this technical process; Suspended substance can be cut down more than 90%, and COD can cut down 45 ~ 60%, and NH3-N, TN can cut down 40 ~ 60%; PO43-P, TP can cut down more than 80%, and the water quality in natural pool can keep showing the IV class standard of quality standard of water environment (GB3838-2002) basically.
