Description

A sewage treatment device for catering

technical field

  The utility model relates to the technical field of sewage treatment, in particular to the field of a sewage treatment device for catering.

Background technique

Kitchen sewage contains waste, grease and other substances, which are perishable and emit stench. Its properties and odor will have a bad impact on environmental sanitation, and it is easy to breed harmful substances such as pathogenic microorganisms and mycotoxins. Discharge of kitchen sewage to the outside without treatment will cause the following problems: 1. It will cause serious pollution of groundwater. Catering sewage contains mostly fats and vegetable oils. When the sewage is discharged into the water, the oil floating on the water will affect the air and Oxygen exchange at the water interface, the oil dispersed in the water can be oxidized and decomposed by microorganisms, so the oil not only reduces the reoxygenation rate, but also consumes dissolved oxygen in the water, resulting in the gradual dominance of the anaerobic bacteria in the microorganisms. Because the anaerobic flora cannot digest organic matter completely, many intermediate products with foul smell are produced. These substances can produce black iron sulfide precipitates when they encounter iron. If this situation is not effectively stopped, the water quality of the natural water body will turn black and smelly in a short period of time, and become stagnant water, which will seriously affect the natural landscape, reduce the quality of life of residents near the water body, and destroy the ecological balance of the natural water body , reducing the water cost. 2. When the sewage from the catering industry is directly discharged into the urban sewage pipe network, a large amount of grease and residue in the sewage is very easy to adhere to the wall of the sewer pipe and the large suspended particles, sediment and other substances deposited on it. It gets smaller and smaller, and finally forms a blockage. 3. Due to management loopholes and driven by economic interests, a large amount of oil (commonly known as gutter oil) in the directly discharged catering sewage, after being discharged into the urban sewer, part of it is illegally collected, illegally used, and even reprocessed and packaged by illegal traders into "Salad oil" has triggered a series of social problems in terms of health, hygiene, and safety. From the above problems, we can see that the treatment of catering sewage is very necessary and urgent.

At present, in order to treat catering wastewater, various catering oil-water separators have appeared on the market. One type is a large-scale oil-water separator. Separator" The oil-water separator is composed of a slag removal area, an oil-water separation area and an electric control system. The slag removal area is composed of a slag removal container, which is installed in the slag removal container and connected with an automatic slag removal device with the electric control system. The slag container is equipped with waste water inlet and outlet, and the waste water outlet is provided with a grid in the slag removal container. The automatic oil scraping device and heating device connected to the electric control system in the oil-water separation tank, as well as the oil collection tank and the oil collection barrel are composed of; the lower end of the oil-water separation tank is connected with the slag collection tank; The waste water outlet of the container is connected to the drainage pipe network, the automatic oil scraping device is connected to the oil collection tank inside the oil-water separation tank, and the oil collection tank is connected to the oil collection barrel pipeline outside the oil-water separation tank. This oil-water separator realizes the function of oil-water separation, but it also has the following disadvantages: 1. The waste water enters the oil-water separation area, and the waste water is quickly discharged from the drain. The waste water also contains a large amount of grease, and the oil-water separation effect is not good. 2. The oil-water separator occupies a large area and requires a certain site for installation, which makes it impossible to install it in the kitchen renovation space. Installation in public places involves road damage, greening damage, cumbersome approval procedures, and increased construction costs. 3. The structure is complex and the installation and operation are complicated. Due to the above reasons, only a small number of catering business units can realize the installation of oil-water separation devices, which hinders the development of catering sewage treatment equipment.

The other is a small kitchen oil-water separator. Although this type of oil-water separator is small in size, its internal structure design is unreasonable, and the oil-water separation effect is poor. In addition, the separated oil needs to open the upper cover of the oil collection tank. It is cumbersome to scoop out the oil, and after separation, the upper layer of grease has to be scooped out once in a while. If the oil cannot be removed in time, it is easy to stink and produce microorganisms, etc., which will affect the kitchen environment.
