Liquid waste treatment device

Abstract

The invention belongs to the technical field of liquid waste treatment and relates to a liquid waste treatment device with application of an environment-friendly physical material. The device comprises a reaction chamber, wherein a waste gas outlet is formed in the top wall of the reaction chamber; a liquid waste inlet and a liquid waste outlet are formed in two ends of the reaction chamber respectively; at least one catalytic treatment unit is fixed in the reaction chamber and is equipped with at least one catalyst support combination, each catalyst support combination is a set of a pluralityof catalyst support tube bundles adopting fibrous activated carbon as tube walls, and fibrous activated carbon as the tube walls is soaked with a catalyst or contains the catalyst; all the catalyst support tube bundles adopting fibrous activated carbon as the tube walls in each catalyst support combination are covered with a wrapping layer, and the wrapping layer is made of a material capable ofinhibiting liquid from passing through. The liquid waste treatment device is simple in structure and easy to manufacture, meets the requirement of large-scale or small-scale liquid waste treatment, and has quite good popularizing usability.

Description

technical field [0001] The invention belongs to the technical field of waste liquid treatment, and relates to the technology of manufacturing a catalyst loading device for waste liquid treatment by using environment-friendly physical materials, in particular to a waste liquid treatment device. Background technique [0002] Catalytic decomposition is often used for waste liquid treatment because there are no problems associated with chemicals, by-products, etc., and the reaction proceeds relatively quickly. However, when the catalyst exists in the state of particles, the small specific surface area of ​​the catalyst will inhibit the improvement of the treatment efficiency, and when the gas is generated in the decomposition reaction of the waste liquid components, the reactor must have a channel structure in order to let the gas out of the system To guide the waste liquid to flow upward, this situation is easy to cause catalyst wear and loss. [0003] At present, there are ma...
