Abstract
The invention relates to a riverside combined pond technology and system used for the water purification of a polluted river. A two-stage high efficiency algae pond is combined with a water plant pond. The system contains five parts, namely a hydraulic electrogenerating device, a hydraulic lifting device, a regulation pond, an algae pond and the water plant pond. The hydroenergy of the river is used for power generation so as to lift river water into the regulation pond; then river water enters the high efficiency algae pond; under the combined action of algae and bacteria in the two-stage high efficiency algae pond, the river water is purified, the effluent staying in the algae pond for a certain time enters the water plant pond, the water plant pond is used to remove algae and further purify the water quality, and the treated water finally flows in the river. By adopting the technology and system in the invention to purify the low polluted river, the average removal rates of COD, NH<4+>-N, PO4<3->-P, TP and TN are 58.75%, 66.67%, 42.37%, 48.69% and 51.09% respectively; and the removal rate of Chl-a in the effluent treated by the water plant pond, of the algae pond is 89.68%.
Description
Technical field
The invention belongs to polluted water body and handle and water surrounding recovery technique field, be specially a kind of river of being close to that is used for the polluted river purification of water quality and unite pool technology and system, be mainly used in the purification of water quality of polluted river.
Background technology
In the treatment system to the river, sewage water treatment method commonly used has activated sludge process, stabilization pond, biomembrance process etc. at present.The sewage water treatment method technology maturation that these are traditional, stable water outlet, clearance to organism, suspended solids is all very high, removal effect to bacterium, virus etc. is also better, but to nutritive substances such as the nitrogen that exists in the sewage, phosphorus, can only remove 20%～40% simultaneously, the total nitrogen of water outlet and total phosphorous are still higher, can cause body eutrophication.
Algae pool technology is the improvement technology of a kind of stabilization pond of growing up nearest decades, its existing traditional stabilization pond technology investment is few, working cost is low, manageability, easy and simple to handle, unique algaebacteria symbiotic system is arranged, to the characteristics of organism, suspended solids clearance height and stable water outlet, overcome shortcomings such as traditional stabilization pond overstand, floor space are big simultaneously again.Utilize algae purification sewage in the algae pool both can take out pollution substances such as nitrogen in the sewage, phosphorus cheap, efficiently, can produce a large amount of algae again, these biomasss can be used as feed, fertilizer and fuel etc. and are used, and have certain economic and are worth.
The algae pool is that a kind of capital cost and working cost are lower, simple and convenient operation and maintenance, the technology that organism, nitrogen phosphorus and pathogenic bacteria is all had better treatment effect, but because a large amount of breedings of algae in the efficient algae pool, directly entered receiving water body if do not remove, can cause the hypertrophy of algae in the receiving water body, pollute receiving water body, therefore must carry out algae and stop and separate the water outlet on the efficient algae pool.
At present the separation method of algae comprise natural sedimentation, flocculation, air supporting, centrifugal, filter and biological collect etc.Utilizing the waterplant pool to remove algae is a kind of not only economy but also high-efficiency method.Reed in the waterplant and duckweed all have and restrain the algae effect preferably, and they not only have higher growth rate, can rapid absorption and water of decomposition in nutritive substance such as nitrogen, phosphorus, and shift out water body easily, both can be used as nutrient fodder, can macerate system green manure again, and can bring considerable economic.There is higher removal on the waterplant pool to the algae in the pool water outlet of efficient algae, simultaneously COD, ammonia nitrogen and TP is also had removal effect preferably.
The present invention combines the efficient algae of the two-stage pool with the waterplant pool, river circulates by the undercurrent thruster in the efficient algae of the two-stage pool, and the acting in conjunction by algae and bacterium in the efficient algae of the two-stage pool purifies river.The water outlet on the algae pool enters the waterplant pool that is implanted with reed and duckweed, by removing algae and to the further purification of water quality in the waterplant pool.This associating pool technology is used for low improvement of polluting urban river, can realizes the efficient removal of COD in the waste water, ammonia nitrogen and TP.
