Wastewater treatment device for hotel catering recycling

Abstract

The invention discloses a wastewater treatment device for hotel catering recycling, wherein the wastewater treatment device comprises a treatment box, a treatment tank is fixedly connected to the topof the treatment box, a water inlet pipe is inserted into one end of the treatment tank, two filter plates are arranged between the inner walls of the two sides of the treatment tank, and bottom plates are welded to the bottoms of the two filter plates; baffles are welded to the inner walls of the two sides of the treatment tank, a connecting pipe is inserted into the other end of the treatment tank, the end, away from the treatment tank, of the connecting pipe communicates with the interior of the treatment box, and a connecting plate is inserted into the end, located in the treatment box, ofthe connecting pipe. Large-particle impurities in hotel catering wastewater can be removed through the filter plates, when the large-particle impurities on the filter plates are excessive, the filterplates can be taken out, excessive impurities can be taken away through the bottom plate welded to the bottoms of the filter plates, the filter efficiency is improved through the arrangement of the two filter plates, and one filter plate always works while the impurities are taken out and cleaned.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for hotel catering recycling. Background technique [0002] Catering wastewater has complex components and high concentration, which seriously pollutes the urban environment. The oil in the sewage is easy to condense on the inner wall of the pipe, forming a thick oil layer, which reduces the water passing capacity of the pipe, and even blocks it. It must be treated to make it reach The discharge standard stipulated by the state can only be discharged into urban sewers or directly into other water bodies, otherwise it will have serious adverse effects on the ecological environment and people's daily life; the existing oil-water separation method is mainly based on the density of water and oil Poor, using the principle of gravity sedimentation to remove impurities or complete the separation of oil and water, but this method can only separa...

[0002] Catering wastewater has complex components and high concentration, which seriously pollutes the urban environment. The oil in the sewage is easy to condense on the inner wall of the pipe, forming a thick oil layer, which reduces the water passing capacity of the pipe, and even blocks it. It must be treated to make it reach The discharge standard stipulated by the state can only be discharged into urban sewers or directly into other water bodies, otherwise it will have serious adverse effects on the ecological environment and people's daily life; the existing oil-water separation method is mainly based on the density of water and oil Poor, using the principle of gravity sedimentation to remove impurities or complete the separation of oil and water, but this method can only separate floating oil from water, and the oily wastewater needs to be left standing for a long time during the separation process, so there will be oil and water Low separation efficiency, long time consumption, and incomplete oil-water separation. Secondly, the sewage entering the oil-water separator contains a large number of impurities with large particles. These impurities seriously affect the treatment effect of the oil-water separator, making it practical less effective
