Sewage purification device with resin immobilized laccase filter layer

Abstract

The invention discloses a sewage purification device with a resin immobilized laccase filter layer. The sewage purification device comprises a purification barrel, wherein the back surface of the purification barrel fixedly communicates with an overflow pipe; the other end of the overflow pipe communicates with a sewage pool; the side surface of the purification barrel is provided with a temporarystorage device; the back surface of the purification barrel is provided with a driving device; and the purification barrel is internally provided with a liquid level control device. According to theinvention, continuous scraping operation is carried out on the inner wall of a net cage through a cleaning device, so the problem that resin immobilized laccase particles are attached to the inner wall of the net cage and block net holes is solved, the permeability of the net cage is improved, the flow resistance of sewage is reduced, energy consumption is lowered, water treatment efficiency is enhanced, and sewage purification cost is decreased; and through cooperation of the driving device, a stirring device, the cleaning device, a discharging device, a limiting device and a clamping device,people can conveniently fish out resin immobilized laccase particles in the stirring device and replace the resin immobilized laccase particles, a replacement mode is simple and convenient, and the practicability of the sewage purification device with the resin immobilized laccase filter layer is improved.

Description

Technical field [0001] The invention relates to the field of sewage purification equipment, and more specifically, to a sewage purification device with a resin-cured laccase filter layer. Background technique [0002] Laccase is a kind of polyphenol oxidase containing four copper ions. It belongs to copper blue oxidase. It exists in the form of monomeric glycoprotein. Laccase exists in mushrooms, bacteria and plants, and can also survive in the air and react. The only product of the latter is water, so it is essentially an environmentally friendly enzyme. The unique catalytic properties of laccase make it widely used in biological detection. As an efficient biological detector, it becomes a substrate, coenzyme, inhibitor, etc. Effective tools and methods of component analysis, because environmental awareness has gradually been valued in recent years, laccase has also become the research object of many scholars in recent years, because laccase has a wide range of substrate specifi...

Problems solved by technology

[0003] The existing sewage purification device with a resin-cured laccase filter layer consists of a barrel body, a water inlet pipe, a water outlet pipe, a net cage, and resin-cured laccase particles. The net cage is fixed inside the barrel body, and the resin-cured laccase particles are filled Inside the net cage, during use, the sewage passes through the gap between the net cage and the resin-cured laccase particles, and the resin-cured laccase is used to purify the sewage. However, the resin-cured laccase particles will be degraded by the water flow of the sewage Attached to the inner wall of the cage and block the mesh, the permeability of the cage is reduced, the flow resistance of sewage is increased, the energy consumption is increased, the water treatment efficiency is reduced, the cost of sewage purification is increased, and the resin-cured laccase is long-term During the use of time, there are problems of activity reduction, denaturation, and inactivation. The resin-cured laccase needs to be replaced. The replacement method is very complicated. Therefore, it is urgent to design a sewage purification device with a resin-cured laccase filter layer.
