Embodiment 1

[0035] Such as figure 1 Shown, the method for the efficient treatment of black and odorous water body of the present embodiment comprises the steps:

[0036] Take out part of the black and smelly water, add medicine to the taken out black and smelly water, control the uniform distribution of the medicine in the taken out black and smelly water, and form drug-containing sewage;

[0037] The medicated sewage is filtered through the high-efficiency filter tank and then enters the clean water pool;

[0038] The jet pump sucks the water in the clear water pool and the outside air to form an air-water mixture;

[0039] The air-water mixture is released into the black and odorous water body to aerate the black and odorous water body.

[0040] The medicaments added in the black and odorous water taken out are flocculants and deodorants.

[0041] The method for efficiently treating black and odorous water bodies in this embodiment is to extract a part of the black and odorous water,...

Embodiment 2

[0044] On the basis of the above-mentioned embodiments, the filtering process of the filter tank is as follows: the medicated sewage is input into the filter tank, and the medicated sewage is controlled to pass through the filter bed of the filter tank from bottom to top in the filter tank.

[0045] In this embodiment, the water in the filter tank passes through the filter bed of the filter tank from bottom to top, so that not only the effect of filtration but also the effect of sedimentation are provided in the process of filtering, and the sludge in the water will naturally form under the action of gravity. settlement. In this way, the sludge deposited on the filter bed can be reduced, and the continuous working time of the filter tank can be extended.

Embodiment 3

[0047]On the basis of the above embodiments, the method for effectively solving black and odorous water bodies in this embodiment further includes the step of setting plant floating islands: setting plant floating islands above the aeration position, and setting soft fillers on the plant floating islands.

[0048] The method for efficiently treating black and odorous water in this embodiment places plant floating islands above the position where the aerated clear water is released, and arranges some soft fillers on the floating islands. With the long time of oxygenation, the fillers are loaded with a large number of microorganisms. The removal rate of COD, ammonia nitrogen, and suspended solids in the river has been improved, and the dissolved oxygen and flow rate in the river have also increased.

Abstract

The invention discloses a method for efficiently treating black and odorous water bodies, and mainly aims at the problems of slow effect and high investment in existing black and odorous water bodies, and proposes a method for efficiently treating black and odorous water bodies with less investment and quick results. The method The method includes the following steps: taking out part of the black and smelly water, adding medicament to the taken out black and smelly water, controlling the uniform distribution of the medicament in the taken out black and smelly water to form drug-containing sewage; performing desliming treatment on the drug-containing sewage to remove the sewage in the black and smelly water mud to form deslimed clear water; aerate the deslimed clear water to form aerated clear water; release the aerated clear water into black and odorous water. The invention has the advantages of large amount of treated water, small occupied area and low investment cost.

Description

technical field [0001] The invention relates to the fields of environmental engineering and sewage treatment, in particular to a method for quickly and efficiently solving black and odorous water bodies in river courses. Background technique [0002] Landscape water bodies such as lakes and rivers in cities are an important part of urban human settlements, but due to their characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water bodies, they are easy to become the recipients of domestic sewage, rainwater and garbage for residents. body, resulting in a large consumption of dissolved oxygen in the water body, resulting in the lack of oxygen in the water body and a black and odorous state, causing the entire ecosystem to be in crisis. Black and smelly urban rivers have become a common pollution problem in many large and medium-sized cities in my country. Black and smelly rivers are a common phenomenon in urban river networ...
