Description

Mane carbon biological contact oxidation reaction device

technical field

The utility model relates to a sewage treatment device, in particular to a mane charcoal biological contact oxidation reaction device.

Background technique

We know that there are many kinds of biological contact oxidation reaction devices at present, such as: water slag, composite packing, ceramsite and other biological contact oxidation reaction devices, but most of these devices are relatively expensive, and some of them have not very good treatment effect.

Contents of the invention

In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a mane charcoal biological contact oxidation reaction device with simple structure, convenient manufacture, low cost and energy saving.

The purpose of this utility model is achieved by adopting the following technical scheme: a kind of bristle charcoal biological contact oxidation reaction device, which is mainly composed of pool body, filler and support, aeration device, water inlet and outlet, three-dimensional membrane filter screen, mud discharge port and The backwashing system is composed of the tank body from bottom to top are mud discharge outlet, water inlet pipe, water distribution pipe, aeration device, grid support, three-dimensional membrane filter, water outlet pipe and backwash outlet. The filler of the biological contact oxidation tank is mane carbon, and the mane carbon biological contact oxidation tank is equipped with a three-dimensional membrane filter under the water outlet. The filter material is three-dimensional filter cloth, which is a new type of purification material, which has the advantages of high filtration efficiency and not easy to block. The application scheme of the utility model is to fix this kind of three-dimensional membrane filter cloth on the bottom of a cylindrical frame without a cover to form a three-dimensional membrane filter net, then turn it upside down and fix it in the mane carbon biological contact oxidation pool under the water outlet . It is used to replace the overflow weir, so that the whole device has a compact structure and saves space; the water outlet effect is good, and the problem of turbidity in the outlet water of the biological contact oxidation tank is more effectively solved.

The utility model fills the mane charcoal with large specific surface area, light weight, environmental protection and easy biofilm as a filler into the mane charcoal biological contact oxidation pool. After the microorganisms are inoculated, cultivated and domesticated, they can quickly form Biofilm, so the organic matter in sewage is purified under contact oxidation; the aging biofilm produced in the process of purifying sewage will naturally fall off under the action of the shear force of water flow generated by biofilm and sewage.

The technological process is briefly described as follows: sewage flows from the water inlet pipe into the mane carbon biological contact oxidation tank through the water distribution pipe, and the air enters the oxidation tank through the aeration device. When the sewage passes through the oxidation tank, the filler intercepts the suspended solids in the sewage, and at the same time adsorbs the colloid and dissolved substances on its surface. The organic matter makes the microorganisms multiply quickly and gradually forms a biofilm. After the biofilm is formed, the microorganisms inhabiting the biofilm ingest the organic pollutants in the sewage as nutrients, and oxidize and degrade the organic matter in the sewage, so that the sewage is purified after passing through the biological contact oxidation tank.

The utility model has the following advantages:

(1) The mane carbon biological contact oxidation tank is equipped with a three-dimensional membrane filter under the water outlet, which is used to replace the overflow weir in the traditional device, so that the whole device has a compact structure and saves space; the water outlet effect is good, and the solution is more efficient. The problem of turbidity in the effluent of the biological contact oxidation pond has been solved.

(2) The mane carbon biological contact oxidation tank has good sewage treatment effect, simple operation, low energy consumption, and high economic and environmental benefits.

(3) Mane charcoal, as a new type of contact oxidation tank filler, has the characteristics of large specific surface area, light weight, environmental protection, and easy formation of biofilm, and plays a good role in oxidizing and degrading organic matter.

(4) The raw materials of the filler bristle charcoal are cheap and easy to obtain, and the manufacturing process is simple and easy.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment: As shown in Fig. 1 and Fig. 2, the grid support 6 in the mane charcoal biological contact oxidation pond body 1 is filled with mane charcoal particles, sufficient dissolved oxygen and suitable water temperature and pH value are provided, and then added Nutrient solution, for hanging film. Sewage enters the mane carbon biological contact oxidation tank body 1 through the water inlet pipe 2 through the water distribution pipe 4 . The aeration device 5 is above the water distribution pipe. The aeration device adopts a perforated pipe with small resistance and low energy consumption to distribute air. There are multiple air outlets on it. The air enters the body of the bristle carbon biological contact oxidation tank through the aeration device 5 1. When the sewage passes through the oxidation tank, the filler intercepts the suspended solids in the sewage, and at the same time adsorbs the colloid and dissolved substances on its surface. The organic matter in it makes the microorganisms multiply quickly and gradually forms a biofilm. The biofilm in the mane carbon biological contact oxidation tank body 1 is in a fluid state due to aeration, and the pollutants in the sewage rely on the oxygenation and stirring of the aeration to fully contact with the biofilm grown on the mane carbon, and the sewage The pollutants in the medium can be efficiently degraded. The microorganisms inhabiting the biofilm absorb the organic pollutants in the sewage as nutrients, and oxidize and degrade the organic matter in the sewage, so that the sewage can be purified when it passes through the biological contact oxidation tank. The treated water flows out from the water outlet pipe 3 after being filtered by the three-dimensional membrane filter screen 8 of the mane carbon biological contact oxidation pond body 1 . The filter material of the three-dimensional membrane filter screen 8 is a three-dimensional filter cloth, which is a new type of purification material with the advantages of high filtration efficiency and not easy to be blocked. The three-dimensional membrane filter screen 8 is formed by fixing this three-dimensional membrane filter cloth on the bottom of the cylindrical frame without a cover, and then it is inverted and fixed under the water outlet of the mane carbon biological contact oxidation tank. It is used to replace the overflow weir in the traditional device, so that the whole device has a compact structure and saves space; the water outlet effect is good, and the problem of turbidity in the outlet water of the biological contact oxidation tank is more effectively solved.

In order to solve the problem of easy blockage in the oxidation tank, this device provides two methods: a mud discharge port 7 is provided at the bottom of the mane carbon biological contact oxidation tank 1, so that the aged and fallen biofilm can be smoothly discharged from the mane carbon biological The other function of the contact oxidation tank 1 and the mud outlet 7 is as the water inlet of the backwashing device, and forms a set of backwashing system with the backwashing water outlet 9 . Designed for water flushing, water enters the pool body 1 through the mud discharge port 7, washes away the aged biofilm and suspended matter, and discharges it through the recoil outlet 9; the treatment capacity of the bristle charcoal biofilm is restored.
