Abstract
An oxygen-exposure-free type ammonia nitrogen removal method for river water is designed to be used for slightly-polluted rivers and is a novel solution to ammonia nitrogen, COD (chemical oxygen demand) and the like in river water. A spillover dam is designed to decrease water flow rate and increase dissolved oxygen in water, and then the river water flows through differently arrayed biological belts and a submerged plant area, so that the ammonia nitrogen in the river water is cut down.
Description
Technical field
The invention belongs to field of environment engineering technology, be specifically related to a kind of method of utilizing modification ribbon ribbon, composite flora, overfall dike, plant etc. to remove the ammonia nitrogen in the polluted river water.
Background technology
The water body reinforcement purification techniques is in recent decades both at home and abroad for solving the focus technology that water pollution is researched and developed; Its outstanding feature is to give full play to the effect of existing hydro project; Natural resources such as the inside and outside wetland in comprehensive utilization waters, beach, pool, levee slope and manual board become material, and natural waters automatic recovery ability and self-purification capacity are strengthened.
River strengthened purification Study on Technology and application are started from Japan, the U.S. and some developed countries of Europe in twentieth century five, the sixties abroad.These countries were in rapid economic development period at that time; All there are every day a large amount of undressed trade effluents and sewage to enter river nearby; The result causes the river to become extremely stagnant rapidly, and water quality extremely worsens, and the dissolved oxygen content in some river is almost nil; Had a strong impact on the functions of use of water resources, like the Jiang Huchuan of the Homewood canal of Rhine in the Thames of Britain, Europe, the U.S. and Mississippi, Japan and Duo Mo river or the like.To this situation, these national governments strengthen the construction dynamics of municipal sewage plant on the one hand, reduce the amount of the pollution substance that gets into the river, and at present, the wastewater treatment rate of Japan, the U.S. and some developed countries of Europe reaches more than 90%.Be exactly on the other hand to begin to take the artificial-strengthening control techniques directly to administer the river of pollution, quicken the recovery of water quality of river according to the characteristics in national river.
Because the nearly stage Economic development of China is rapid, has produced a large amount of industry, agricultural and domestic refuse, these rubbish directly do not enter the river course through proper process, and are very big to the ecosystem destruction in river course.For some urban rivers, the influx of rubbish is considerably beyond its self-purification capacity, and direct result is exactly river blackening, fouling.Some indexs such as the ammonia nitrogen in the river have surpassed state specified standards greatly, if harness a river, reduce its healthy ecology, have become the focus of domestic scholars in this field.
Summary of the invention
The object of the present invention is to provide a kind of method of removing ammonia nitrogen in the polluted river water.
Technical scheme of the present invention is:
Utilize the overfall dike of design, reduce the velocity of flow of river, after flow velocity has reduced, oxygen in water is increased.Then river is through the pool district, when river when the ribbon zone in pool district is flow through, will get rid of most ammonia nitrogen through the ribbon and the composite flora that adheres on it of modification, its principle is the huge surface-area of modification ribbon, makes the two full contact.On the other hand, composite flora decomposes the ammonia nitrogen in the sewage in a large number.Through the river that the pool district purified, continue to flow through the submerged plant district of back, a nearly step of plants such as reed, cattail, Canna generalis Bailey absorbs the ammonia nitrogen in the water, strengthens the effect of removing ammonia nitrogen.
Embodiment:
Harness a river foremost, build an overfall dike with cement, fragment of brick, its gradient of meeting to water (flow) direction is 60 degree, the gradient of opposite side is 100 degree, it highly is lower than water surface 5cm, pegtop paving is used on the surface.Overfall dike is apart from pool district 2m, and the pool district degree of depth is 0.7m, wide 4m.The modification ribbon evenly is coated with on it with polyacrylic ester, and is 1: 1.5: 1 with ratio: the composite flora of 2: 3 yeast, actinomycetes, milk-acid bacteria, subtilis and flocculated bacteria is fixing on it.Interval 5cm between the ribbon, ribbon width 2cm, long 0.8m, ribbon peak width are 3m.Pool district and submerged plant interval thereafter are divided into 2m, and the submerged plant section length is 5m, and plant selects for use cattail, reed, Canna generalis Bailey to mix plantation.
Claims (2)
1. do not have the oxygen of exposing to the sun formula river ammonia nitrogen removal method, it is characterized in that constituting by overfall dike, three treatment steps of modification ribbon and submerged plant mixing zone.
2. according to the said method of claim 1, it is characterized in that it is the 15-75 degree that overfall dike is met to the water (flow) direction gradient, opposite side is the 90-120 degree, highly is lower than WS 1-10cm, and the ribbon in itself and pool district is interval at a distance from 0.5-5m, pool district degree of depth 0.5-2m.Ribbon adopts high molecular polymer to be filled in it, thereby ribbon is carried out chemical modification, increases the specific surface area of ribbon; The composite flora that yeast, actinomycetes, milk-acid bacteria, subtilis, flocculated bacteria and the X bacterium of configuration suitable proportion formed is combined on the modification ribbon it, to realize the efficient removal of ammonia nitrogen.Interval 5-15cm between the ribbon, ribbon width 1-5cm, long 1-5m.Be spaced apart 0.5-5m between ribbon zone and the plant zone, the floral region length of field is 1-6m, and plant is selected two or more in cattail, reed, Canna generalis Bailey, mullet grass, Arundo donax, the floral leaf Scirpus tabernaemontani etc. for use, and mixing is planted.
