Description

Biological purification system for treating black and odorous water body in river channel

Technical Field

The invention belongs to the technical field of water treatment, and particularly relates to a biological purification system for treating black and odorous water in a river.

Background

In recent years, with the rapid development of urbanization and human society, the environmental load capacity is seriously forced due to the generation of pollutants, the discharge amount of waste water is increased day by day, and the self-cleaning capacity of water bodies is continuously reduced. Water pollution, especially urban river pollution, has become an important environmental problem that cannot be avoided. At present, under the multiple driving of policy requirements, target guidance and practical requirements, the phenomenon of black and odorous water in urban built-up areas becomes a key problem concerned in the field of environmental protection.

The black and odorous phenomenon of the water body has the same mechanism, mainly because the dissolved oxygen content in the water is low, and the black and odorous phenomenon is related to eutrophication and sediment deposition of the water body. The pollutants enter the water body to consume DO in the water body, so that the water body is in an anoxic and anaerobic state, the odorization process and the blackening process in the water simultaneously occur, and the metal ions are combined with sulfur ions to generate FeS and other blackening substances which are adsorbed on the suspended particles to enable the water body to be black; the volatile organic sulphur compounds formed in the reaction produce a major malodorous gas. And secondly, ammonia gas, hydrogen sulfide and the like generated by anaerobic decomposition of organic matters can also cause the water body to emit odor. The main causes of the black and odorous water body are summarized into two points, namely exogenous pollution caused by pollutant input and endogenous pollution caused by sediment deposition. In addition, the urban river channel is bent and straightened, the hydrodynamic force is insufficient, and normal water circulation cannot be carried out, so that an 'foul water ditch' is formed. Aquatic animals and plants can not survive, an ecological system is damaged, the water body loses the self-cleaning capacity, and the water body is in a black and odorous state due to repeated accumulation and vicious circle.

The black and odorous water in the riverway affects the life and health of surrounding residents, damages the harmony of urban landscape, and simultaneously leads to the death of a large number of animals and plants in water, thereby threatening the ecological balance of water.

When the existing biological ecological method is used for treating black and odorous water in a river channel, sundries in the black and odorous water need to be cleaned by workers after being filtered, so that the workload of the workers is increased, and if the sundries are not cleaned in time, filter grids can be blocked, so that the water body treatment efficiency is influenced; the contact time or contact area with the biological filler is small, and the water quality after treatment cannot be ensured; when coagulating sedimentation or odor removal is carried out, relevant medicaments are required to be sprayed, the medicaments cannot be fully mixed with river water, the dosage of the added medicaments in the water body at the bottom end of the river is small, and the water body cannot be fully treated; most of the existing sedimentation tanks are open, so that impurities in the air can be blown into the sedimentation tanks along with wind to form secondary pollution.

(3) the river water treated by the deodorization treatment zone 2 enters the anaerobic treatment zone 3, at the moment, the water enters the interior of the river water through the plurality of through holes 710 of the outermost biological filler frame 71, then sequentially passes through the biological filler frames 71, and organic matters, particularly complex high molecular substances or long-chain macromolecular compounds in the water are degraded by utilizing the microbial filler frames 711 on the side walls of each biological filler frame 71 and anaerobic bacteria and are converted into simple low molecular substances;

(4) the river water treated by the anaerobic treatment zone 3 enters the aerobic treatment zone 4, at the moment, the water enters the interior of the anaerobic treatment zone through the plurality of through holes 710 of the outermost biological filler frame 71, then sequentially passes through the biological filler frames 71, and is subjected to nitrogen and phosphorus removal treatment and organic matter removal treatment by utilizing the microbial filler frame 711 on the side wall of each biological filler frame 71 and aerobic bacteria, in the process, external air is pumped to the filler stirring rod 80 through the air pump 81 and is aerated through the aeration holes 800;

(5) the water body treated by the water body in the aerobic treatment zone 4 enters a precipitation separation zone 5, impurities in the treated water body are precipitated and separated by the precipitation separation zone 5 and then discharged, when impurities in the air are blown to the upper end along with wind, the rotating teeth 5010 can be driven by the motor 502 to rotate towards the discharge port 51 side at the upper end of the horizontal flow type sedimentation tank, meanwhile, the impurities at the upper end of the slag salvaging net 500 are pushed to the discharge port 51 by the slag pushing disc 5011, the cover plate 510 is pushed outwards to be pushed away, and the impurities are discharged into the containing box 504;

(6) when anaerobic treatment zone 3 and aerobic treatment zone 4 handle the river course water, still can insert the river course bed mud with the bayonet joint 7212 that corresponds on each grafting anchor 721 through the extension of electric telescopic handle 722, be fixed in the river course with biological purification case 7, at the in-process in bayonet joint 7212 river course, because a plurality of resistance-increasing wings 7211's setting, increase the resistance that the device removed in the bed mud, improve biological purification case 7's stability.
