Problems solved by technology

The current treatment technologies for black and odorous water bodies mainly include in-situ treatment technology and ex-situ treatment technology. Disadvantages such as slow, unchanged installation and difficult post-maintenance
At present, many researchers have conducted a lot of research on in-situ and ex-situ restoration technologies for black and odorous water bodies. Most of them increase the amount of dissolved oxygen in the water body by increasing the amount of aeration, so that the microorganisms in the water body can act and enhance the self-purification ability of the water body. , but its effect is slow, and it is greatly affected by many factors such as the environment, and the governance effect may not be very good

example 1

[0038] In the urban water environment, in some areas, due to the unreasonable construction of the drainage pipe network or the sewage from the sewage treatment plant in rainy days is directly discharged into rivers or lakes through the mixing of rainwater, some rivers or ponds have black and odorous phenomena, and black and stinky in subsequent towns. In the process of treating foul water bodies, although long-term planning has been carried out and centralized planning and treatment of water bodies have been carried out, including macro-control such as interception and control of sources, re-planning of pipe networks, diversion into rivers, etc., generally the treatment period is long, and some even need to build water conservancy and Pipe network equipment, which greatly prolongs the construction period. During this period, sewage will continuously flow into natural water bodies, causing great trouble to the treatment of water environment. At this time, this equipment can rely ...

[0041]There are local black and odorous phenomena in corresponding rivers or ponds in my country. The phenomenon is caused by many aspects. It can be mainly divided into water pollution and sediment pollution. Generally, the cycle of sediment treatment is long, and the effect is difficult to be effective in a short period of time. , so in municipal governance and short-term planning, this equipment can be used for emergency treatment of water bodies, which can make water quality up to standard in a short time, and combined with sediment treatment equipment, under the synergistic effect of the two, water bodies can be made more quickly Restore self-purification ability and improve water quality.

[0042] Similarly, this equipment has a complete water treatment process, which can provide emergency assistance to the sewage treatment plant in the case of excessive operation of the sewage treatment plant, and reduce the treatment pressure of the sewage treatment plant, thereby avoidin...

Abstract

The invention discloses movable black and odorous water body treatment equipment. The equipment comprises an intelligent water taking head and a container type box body, wherein the container type boxbody is a main treatment unit. Main working units in the box body are a biological aerated filter and a biological rotating disc, and the whole equipment mainly works under physical-chemical-biological combined action. According to the invention, a Fenton reagent added into the coagulation reaction tank can effectively reduce the black and odorous phenomena of a water body, subsequent sludge backflow can reduce the addition of the reagent, and the secondary pollution of the chemical reagent to the environment is effectively reduced under the subsequent treatment of an ecological floating bed,the biological aerated filter and the biological rotating disc. Through combined treatment of a plurality of treatment units, the equipment can efficiently and reliably remove nutrient substances such as nitrogen and phosphorus in a water body under the action of microorganisms and catalytically degrade macromolecular organic matters, so various indexes of the water body reach the first-grade A standard of national emission standards.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a movable black and odorous water treatment equipment. Background technique [0002] In recent years, with the country's emphasis on environmental protection, the governance of water environment, especially the governance of black and odorous water bodies, has gradually entered people's field of vision and become the focus of current research. Water black and odor is a complex biochemical phenomenon, and its water quality indicators mainly include dissolved oxygen (DO), odor threshold, transparency value (SD), and chromaticity. In most of the black and odorous water bodies in our country, most of them are caused by the fermentation of microorganisms in the water body and the decomposition of organic matter to produce a large amount of odorous gases such as sulfide and hydrogen ammonia. Deterioration reaction, resulting in black and odorous water. [0003] The blackenin...
