Problems solved by technology

[0005] (2) The chemical method mainly uses the oxidation-reduction properties of electrochemical or chemical agents to oxidize the organic matter in the water. The chemical method has a good treatment effect and a fast rate, but the operating cost is too high for high-concentration residual black liquor, and it is difficult to apply in practice.
[0007] The main pollutants in wastewater are macromolecular organic substances that are difficult to degrade, such as cellulose, hemicellulose, lignin, and polypentose. The biodegradability is poor, and aerobic biological treatment technology alone often fails to achieve satisfactory results.

Embodiment Construction

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention, embodiments of the invention being illustrated in detail below with reference to the accompanying drawings.

[0022] exist figure 1 Among them, the water storage tank 10 is connected with the pressure device 16 through the crushing device 12 and the fluid pump 14 . The pressure device 16 is connected to a compressed air source, wherein the compressed air is introduced into the container 16 through a first pipeline, and the first pressure detection sensor 20 and the second pressure detection sensor 22 are connected to the pressure device 16 . Wherein the pressure device maintains a pressure of 5-6 bars, and if the preset pressure is reached, the pressure detection sensor 24a closes the valve 26c, thus cutting off the supply of compressed air leading to the pressure ...

Abstract

The invention relates to a multilayer sleeve settlement wastewater purifying and processing system, and purified water processing method. A grinding device is connected to a pressure device, the pressure device and a compressed air source are connected to a pressure reducing device; an external cylinder part, an internal cylinder part, and a middle cylinder part which is arranged between the internal cylinder part and the external cylinder part, are arranged in the pressure reducing device; circular channels are formed between the three cylinders, floating wastes and clean water can be high efficiently separated by the settling effect generated by the sleeve structure, and expensive and tedious separation technologies are not needed. The device is easy to operate, the procedure is simple and reliable, the investment and operation cost are low, and the system has the advantages of no sludge backflow, low noise, no odor, long service life, little occupied space, and good purifying effect, and is capable of greatly reducing the solid contents in the clean water.

Description

technical field [0001] The invention relates to a wastewater purification treatment system and a water purification treatment method, in particular to a multi-layer sleeve settlement wastewater purification treatment system and a water purification treatment method. Background technique [0002] Sewage treatment is an energy-intensive integrated technology. For a period of time, high energy consumption and high operating costs have hindered the construction of urban sewage treatment plants in our country to a certain extent, and some of the built treatment plants have also stopped production or semi-stop production due to energy consumption. For a long period of time in the future, energy consumption will become the bottleneck of urban sewage treatment. Whether it can solve the energy consumption problem of the sewage treatment plant and carry out reasonable energy distribution has become a key factor in determining the operation efficiency of the sewage treatment plant. L...
