Restaurant waste water treatment device capable of uniformly aerating, increasing oxygen and promoting activity

Abstract

The invention discloses a restaurant waste water treatment device capable of uniformly aerating, increasing oxygen and promoting activity. The structure of the device comprises a treater, an upper cover, a handle, a flange plate, a water draining pipe, a supporting pipe, a waste water pipe, a supporting frame and a connecting pipe, wherein the upper surface of the treater clings to the lower surface of the upper cover; the treater comprises a housing, a supporting rod, a liquid outlet port, a filler, an oxygen promoting separating device and a water inlet. The device has the beneficial effectsthat the water pressure is increased under the effects of a biological film growing pipe and a reaction pipe, so that the water scouring force is increased, and the probability of blockage is effectively reduced; fillers can be effectively dredged under the effect of the separating device, and an aged biological film can be separated, so that the growing space for a new biological film is effectively expanded; oxygen can be uniformly effectively supplied through an aerator, so that sufficient oxygen is supplied to the biological film, and the biological film growing power is improved; the activity of the biological film is promoted; and the effect of the biological film in treating restaurant waste water is effectively improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a catering wastewater treatment equipment for uniform aeration, oxygen enhancement and activation promotion. Background technique [0002] Catering wastewater is mainly a mixture of various wastewater generated during the business process of the catering industry, including slops and swill produced in the process of washing vegetables, washing rice, cooking and washing dishes. Among them, catering wastewater generally adopts biological contact oxidation method, Among them is to fill the filler in the treatment equipment. When the oxygenated sewage passes through the biofilm on the filler at a certain flow rate, it is absorbed and utilized by the microorganisms on the biofilm, thereby removing the pollutants in the sewage. [0003] However, the reaction is mainly processed through the contact between the filler and the catering wastewater. Since the catering wastewater contains...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a catering wastewater treatment equipment that uniformly aerates, increases oxygen and promotes activation, so as to solve the problem that the reaction in the catering wastewater is mainly processed through the contact between the filler and the catering wastewater. Contains a large amount of suspended matter, of which the suspended matter is food debris, and the filler is easy to be blocked, which makes its treatment relatively difficult, and it is easy to cause local dead corners, which hinder aeration, resulting in uneven aeration and insufficient support on the filler , causing the biofilm to produce anoxic phenomenon, making it difficult for microorganisms to be ingested and utilized, which affects the treatment effect of catering wastewater
