Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a nylon 6 wastewater treatment device. Background Art

[0002] The monomer of nylon 6 is caprolactam, which is a polymer compound formed by the polymerization of caprolactam. The chemical and physical properties of nylon 6 are very similar to those of nylon 66. However, it has a lower melting point and a wide process temperature range. Its impact resistance and solubility resistance are better than those of nylon 66 plastic, but its hygroscopicity is also stronger. Because many quality characteristics of plastic parts are affected by hygroscopicity, the current treatment of this wastewater mainly adopts anoxic + aerobic, that is, (a / o) process. In order to maintain the removal efficiency and meet the effluent indicators, it is often necessary to mix with a large amount of domestic sewage or dilute with clean water before entering the system for treatment, resulting in huge treatment facilities, low load, and high energy consumption. In addition, as the amount of pollutants removed in the aerobic process increases, the amount of biochemical sludge will also increase. Therefore, a mobile substation monitoring device is now being promoted and used on the market;

[0003] Among them, the "nylon 6 wastewater treatment equipment" disclosed in the application number "CN201921611358.2" is also an increasingly mature technology. It "includes a homogenizing regulating tank, a primary sedimentation tank, a photocatalytic oxidation tank, a catalytic oxidation flotation tank, an A / O biochemical tank and a secondary sedimentation tank. The regulating tank has a relatively low installation height. The inlet of the regulating tank is connected to the sewage collection network of the plant area. The outlet of the regulating tank is connected to the inlet of the primary sedimentation tank through a lifting pipe. A lifting pump is installed on the lifting pipe. The outlet of the primary sedimentation tank flows into the photocatalytic oxidation tank by gravity. The outlet of the photocatalytic oxidation tank Water flows by gravity into the catalytic oxidation flotation tank, the effluent of the catalytic oxidation flotation tank flows by gravity into the A / O biochemical tank, the effluent of the A / O biochemical tank flows by gravity into the secondary sedimentation tank, the catalytic oxidation flotation tank is composed of a catalytic oxidation zone and a flotation zone, and the A / O biochemical tank is composed of an anoxic biochemical tank and an aerobic biochemical tank. The utility model can remove pollutants such as chemical oxygen demand (COD), ammonia nitrogen (NH3-N), and total nitrogen (TN) in wastewater, with a small footprint and low investment and operating costs. However, the device still has the following defects in actual use.

[0004] In actual use, the wastewater treatment device is not convenient for better sedimentation and filtration of nylon 6 wastewater in the A / O biochemical pool. The sedimentation tank adopts the traditional sedimentation method, and the sedimentation and filtration time is long, which is not convenient for rapid separation of mud and water, thereby reducing the efficiency of nylon 6 wastewater treatment.
