Problems solved by technology
(3) Emulsified oil, the particle size of oil droplets is less than 10μm, and it is not easy to separate from wastewater
[0003] The main problems existing in the existing fiber ball filter device: Although the existing fiber ball filter device has the characteristics of large sewage interception capacity, high filtration precision, easy backwash regeneration of filter material, and low backwash water loss, the existing fiber ball filter device Easy to cause mechanical damage to the fiber filter material, resulting in reduced service life of the existing fiber filter material
At the same time, the existing fiber ball filter device cannot remove the COD in the wastewater during the filtration process, and the removal rate of the oil in the wastewater is also very low, and the effluent standard is difficult to meet the water quality requirements of the membrane, resulting in high cleaning frequency of the reverse osmosis membrane. The problem of low service life

Abstract
The invention relates to a multiple-effect carbon fiber filtering device for organic waste water. Filtering materials of the filtering device adopt spherical carbon fibers, and waste water containing oil and high-concentration organic matters in metallurgy, coal chemical industry, electric power, petrifaction, papermaking, spinning, printing and dyeing, municipal administration and the like can be effectively treated. The multiple-effect carbon fiber filtering device is characterized by comprising a tube body with an upper sealing end and a lower sealing end, wherein the upper part in the tube body is provided with a cyclone water distribution device, the cyclone water distribution device is connected with a waste water inlet, the lower part in the tube body is provided with an air-water cyclone backwashing device, the air-water cyclone backwashing device is connected with a support, the support is connected with the lower sealing end, a filtering material layer is arranged between the cyclone water distribution device and the air-water cyclone backwashing device and is a spherical carbon fiber filtering material layer, and the lower sealing end is provided with a clean water outlet and an air inlet.
Description
technical field [0001] The invention relates to the technical field of water purification by water flow filtration treatment, in particular to a multi-effect carbon fiber filter device for organic waste water. Effective treatment of wastewater containing high concentrations of organic matter or oil in textile, printing and dyeing, and municipal administration. Background technique [0002] High-concentration organic wastewater generally refers to wastewater with COD above 2000mg / L discharged from industries such as metallurgy, coal chemical industry, petrochemical industry, papermaking, leather and food. These wastewaters contain a large amount of organic pollutants such as phenol cyanide, oil, biphenyl, pyridine, indole, and quinoline. The pollutants have high color and are very stable in nature. It is difficult to remove organic matter and chroma. If they are discharged directly, they will cause serious pollution. Oily wastewater mainly comes from petrochemical, iron and ...
