Problems solved by technology

[0003] At present, the commonly used methods are artificial aeration, sediment dredging and water diversion, etc. However, these methods basically treat the symptoms rather than the root cause, the cost of treatment is relatively high, and it is difficult to continue to apply for a long time, and the purified water cannot effectively alleviate the black and odor phenomenon

Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment adopts a black and odorous water treatment device, and the device includes an inlet filter box 1, an aeration blow-off box 2, an ammonia recovery box 3, an aerobic tank 4, a secondary sedimentation tank 5, and an anaerobic tank 6 , reaction tank 7, coagulation reaction tank 8 and membrane treatment device 9; the black and odorous water enters the water inlet filter box 1 through the water inlet pipe, and the water inlet filter box 1 intercepts the particulate pollutants in the black and odorous water body, and is processed by the water inlet filter box The black and odorous water enters the aeration blow-off box for aeration and blow-off. An ammonia recovery device is arranged above the aeration blow-off box 2 to filter the gas after aeration and blow-off. The ammonia recovery device and the aeration blow-off box Sealed connection, and the upper part of the ammonia recovery device 3 is provided with a gas circulation pip...

Embodiment 2

[0036] Improvement is made on the basis of Example 1. The nitrogen and phosphorus recovery adsorption pool is filled with granular composite adsorbents, and the granular composite adsorbents are prepared according to the following steps:

[0037] 1) dehydrating the phosphorus-containing sludge to obtain dewatered sludge; subjecting the dehydrated sludge to wall-breaking treatment, the wall-breaking treatment adopts ultrasonic wave breaking, high-pressure steam breaking or high-pressure fracturing breaking, and the The broken mixture is passed into the separation device for solid-liquid separation to obtain solid and liquid substances;

[0038] 2) fast pyrolysis of said solid matter using a temperature of about 650° C. to produce pyrolysis gas and char, which is recovered or further processed;

[0039] Preferably, the solid matter is mixed into crop straw before pyrolysis, and the crop straw is air-dried and crushed before being mixed in, the particle size is less than 1 cm, an...

Abstract

The invention provides a black and odorous water body treatment device. A nitrogen and phosphorus recycling principle of the prior art is brought into play sufficiently, an aeration blowing tank is adopted to carry out reoxygenation and denitrification synchronous treatment on a black and odorous water body, with the combination of aerobiotic, anaerobic and membrane treatment processes, nitrogen and phosphorus removal treatment on the black and odorous water body is carried out, meanwhile, synchronous removal and recycling effects on ammonia nitrogen are achieved, influence of the black and odorous black body upon ambient environments can be reduced, and certain economic values can be made.

Description

technical field [0001] The invention relates to the field of river water pollution control, in particular to a black and odorous water treatment device. Background technique [0002] Black odor is an extreme phenomenon of organic pollution in water bodies, which is caused by the lack of oxygen in water bodies and the corruption of organic matter. The direct cause of the black and odorous water body is the lack of DO dissolved oxygen, and the discharge of pollutants is the root cause of the black and odorous water body. The phenomenon of river black and odor is actually a biochemical phenomenon, which is the anaerobic decomposition of organic substances in water bodies. It is believed that the oxygen consumption of organic matter in the water body is greater than that of reoxygenation during the decomposition process, resulting in an anoxic environment, and anaerobic microorganisms decompose organic matter to produce a large amount of odorous gas that escapes from the water ...
