Description
Technical field
The utility model belongs to a kind of method of administering sewage, is specifically related to a kind of artificial swamp water body treatment unit.
Background technology
Along with the quickening of Chinese industrial process, the water environment pollution regulation is faced with increasing challenge.Artificial swamp is the recombining process that a kind of natural purification combines with artificial-strengthening, can take suitable scale to adapt to it according to the size of sewage quantity, can be used for the direct processing and the advanced treatment of polluted-water.Artificial swamp is compared with traditional secondary biochemical treatment; Have and build and working cost is low, it is simple to safeguard, effluent quality is good and to advantages such as the load variations adaptive faculty are strong, relatively being suitable for technology management level is not cities and towns or the rural WWT very high, that scale is less.In promoting waste water, under the eucyclic prerequisite of pollution substance, can give full play to the production potential of resource, prevent the recontaminate of environment, thereby obtain the optimum efficiency of WWT and resource utilization, obtain more and more widely research and application.Forefathers discover that to artificial swamp the decline of artificial swamp decontamination effect improving is relevant with the generation of the inner short flow phenomenon of matrix.And at present the research of artificial swamp matrix is mainly concentrated on the loading capacity and detergent power of classification to pollutent of matrix.
The utility model content
The purpose of the utility model just provides a kind of artificial swamp water body treatment unit.Difference according to the PQ of different-grain diameter substrate material; The interstitital texture of reasonably combined matrix; Avoid the formation in short stream and current dead band; Make current at the inner uniform distribution of bed body, give full play to the detergent power of filler, the living space of good in expansion oxygen animalcule, thereby effectively improve the decontamination effect improving of artificial swamp.
The utility model is achieved in that sets up an artificial swamp pond, and body of wall has a feed-water end on the one side in wetland pond, and the other side body of wall in the wetland pond has a water side; Feed-water end and water side respectively are provided with water distribution zone and catchment area, and filling particle diameter is the pebbles of 30mm～50mm; The middle part in artificial swamp pond is that main body packing area (11) divides five layers of wadding warp to cross the silica sand of the different-grain diameter of screening, and the filler fill order is from top to bottom: the first layer packing layer, and filling particle diameter is 0.1～1mm quartz sand filler; Second layer packing layer, filling particle diameter is 0.1～3mm quartz sand filler; The 3rd layer of packing layer, filling particle diameter is 1～3mm quartz sand filler; The 4th layer of packing layer, filling particle diameter is 1～5mm quartz sand filler; The layer 5 packing layer, filling particle diameter is 3～7mm quartz sand filler; The top plantation humidogene emergent of the first layer packing layer.
Sewage is flowed into by feed-water end, and after water distribution zone, horizontal flow is crossed each layer packing layer in the main body packing area, in the terminal catchment area that imports of main body reaction zone, at last by the water side outflow system.
Said humidogene emergent is a kind of in Canna generalis Bailey, reed and the cattail.
Pollutent in the water in the constructed wetland device process of flowing through through adsorb with granular filler, co-precipitation, by plant picked-up, the microbial metabolism effect of being adhered on the filler is removed;
The constitutional features that constructed wetland device main body packing area is filled to bottom by the top layer by the ascending filler of the same race of particle diameter after sieving successively; Can guarantee main body packing area PQ distribution situation from low to high from top to bottom; Avoided the formation in the current dead band at the bottom of short stream in artificial wet land system top layer and the pond, given full play to physics, the chemical purification effect of filler pollutent.Uniform flow's realization can be that more dissolved oxygen is brought in artificial swamp lower floor packing area through the current rolling action simultaneously, thereby enlarges the living space of aerobic microbiological, and the raising system is to the decontamination effect improving of pollutent.
Adopt the utility model that trade effluents such as cities and towns and domestic sewage in rural areas by using, food-processing industry, butchery trade are handled; Can avoid the formation in short stream of current and dead band; When obtaining efficient pollutant removal, have stable, low, the convenient management of investment working cost, advantage such as both artistic and practical.
