Background
Along with the social development and the dramatic increase of population, the urban industrial wastewater, the domestic wastewater, the rural agricultural non-point source wastewater, the aquaculture wastewater and the like are discharged randomly without being treated, so that the contents of nitrogen, phosphorus, nutritive salt and organic matters in the water body greatly exceed the self-purification capacity of the water body. The degradation of organic matters needs to consume a large amount of dissolved oxygen, which easily causes the water body to form an anoxic-anaerobic environment, and the water body is not completely decomposed to generate volatile organic substances such as ammonia nitrogen, hydrogen sulfide and the like under the environment, thereby further causing the black and odorous phenomenon of the water body. Meanwhile, the strong reduction performance of the water body is not suitable for the survival of aquatic organisms, so that aquatic vegetation is degraded or even died, a small amount of pollution-resistant varieties such as phytoplankton, zooplankton, benthos and the like exist, and the ecological balance of the water environment is seriously damaged.
The reoxygenation of river water mainly has the following forms: 1. oxygen in the atmosphere enters a water body through the exchange action of a gas-liquid interface, the starting speed is higher, then the oxygen is gradually reduced, and finally the balance is achieved; 2. the water plant containing photosynthetic pigment in the water body and the algae perform photosynthesis to generate oxygen; 3. and (5) artificial oxygenation.
However, the treatment effect of the method on the river channel is limited because effective water body circulation flow cannot be formed, if the whole river bed sludge is sucked and transferred by adopting a conventional construction mode, although the treatment effect is rapid and obvious, at least millions of river channels are needed in each kilometer, the construction cost is high, huge potential safety hazards exist in the urban river channel construction process, and the influence is also caused on the life of common people.
The existing artificial oxygenation mode is generally an aeration pipe or a microporous aerator or a plug flow aerator, generally adopts a fixed installation mode and adopts a sewage treatment oxidation ditch pool in an application scene, and the existing artificial oxygenation mode is not applied to rivers and can not adapt to the requirements of treating organic pollutants in different black and odorous water bodies, and enabling the concentration indexes of the organic pollutants to reach the standard and running stably.
Even if it is popularized and applied in the river course, and set up on suspension device, but it all adopts the mode of water surface local set point to carry out water surface local aeration, can not effectively form the plug flow of whole river course water, the water of whole river course still is in quiescent condition, the aeration of aeration pipe or micropore aerator or plug flow aerator only plays the effect of oxygenating in addition, can't play the effect of mixing, and its plug flow effect is relatively poor, extremely limited to the treatment effect in river course, await further improvement.
The patent names are as follows: CN202110843717.2, with patent name: a technology for solving the defects is disclosed in the literature of a suspension type rotary disk aerator for a small river channel and a treatment method thereof, and specifically comprises the following steps; the dish aerator is installed on floated base, and the dish aerator includes pivot, drive arrangement and interval suit in the epaxial dish that changes of pivot, and floated base comprises at least one platform form base body, has seted up the aeration zone on the floated base, and the dish is in the river course is soaked by the aeration zone to the dish, and the aeration zone spanes in the width direction of river course, and floated base is dam formula interception form in the river course. Aiming at small-sized riverways, the integral plug flow is carried out on riverway water bodies, so that the aeration and oxygenation can be effectively carried out, and the mixing and plug flow effects can be realized.
