Embodiment Construction

[0041] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the invention, "plurality" means two or more, unless otherwise specifically defined.

[0043] Such as figure 1 Shown, a kind of sewage treatment method, it comprises the steps:

[0044] S1, filtering solid waste in sewage;

[0045] S2, adjusting the pH value of sewage;

[0046] S3, adding a...

Abstract

The invention relates to a sewage treatment method. The method comprises the steps of filtering solid garbage in sewage; adjusting the pH value of the sewage; adding a coagulant into the sewage and conducting stirring; adding a flocculant into the sewage and conducting stirring; conducting standing and treating a sediment. The sewage treatment method is simple in process, convenient to operate, stable in running, low in cost, capable of effectively removing animal and plant oil in the kitchen sewage, effectively solving the problems that currently, the kitchen sewage heavily pollutes sewers, and urban sewage treatment plants have a heavy treatment burden, and protecting the water and the urban environment, and applicable to hotel environments; meanwhile, the water treatment efficiency is improved, the treatment cost is reduced, and a good basis is laid for reuse of recycled water in the future at the same time.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a kitchen sewage treatment method. Background technique [0002] Due to the improvement of living standards and the improvement of people's food quality, the organic pollution of the current sewage such as vegetable washing water and dishwashing water has nearly doubled compared with the original sewage, and the organic pollution is becoming more and more serious. There are more and more restaurants and hotels, and a large amount of kitchen sewage is discharged into urban sewers every day. A large amount of grease and impurities are blocked in the sewer pipe, causing bacteria to grow in an anaerobic state, and even fermenting to produce odor, which affects the sanitary environment and endangers human health. At the same time, pollutants such as animal and vegetable oils in kitchen sewage will also burden the sewage treatment plant and negatively affect its treatment efficiency. ...
