Wastewater treatment settling tank with continuous separation function

Abstract

The invention discloses a wastewater treatment settling tank with a continuous separation function, characterized in that a cylindrical barrel is provided with a water inlet and an overflow port, a conical barrel is provided with a water outlet and a dirt outlet, a stirring chamber, a separation chamber, an overflow chamber and a flow guide chamber are arranged in the cylindrical barrel, the separation chamber is arranged below the stirring chamber and is communicated with the same, a center barrel and oblique plates are arranged in the separation chamber, the center barrel is provided with flow guides, a first filter plate and an upper separation plate are arranged in the overflow chamber, the overflow port is arranged in the sidewall of the overflow chamber, the flow guide chamber is arranged between the upper separation plate and the conical barrel, first filter holes in the first filter plate are less than second filter holes in the oblique plates in size, the sidewall of the center barrel is provided with third filter holes that are less than the first filter holes in size, and a clear water passage is arranged in the center barrel and is communicated with the water outlet. The wastewater treatment settling tank can provide continuous settling separation for wastewater during continuous production.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a settling tank for continuous separation of sewage treatment. Background technique [0002] With the development of social urbanization and technology, the industrial industry has developed vigorously, and more and more factories have sprung up, followed by an increase in the use of environmental protection equipment and the emergence of sewage treatment problems. Sewage contains industrial production materials, intermediate products and products lost with chemicals, as well as pollutants produced in the production process. With the rapid development of industry, the amount of sewage has increased rapidly, and the pollution of wastewater has become increasingly widespread and serious, threatening human health. and safety. Therefore, for the protection of the environment, the treatment of sewage is very important. Settling tanks are often used in the treatment of sewage....

AI Technical Summary

Problems solved by technology

[0003] The settling tanks used in the existing sewage treatment generally adopt static suspending liquid to achieve the purpose of solid-liquid separation. After the solid and liquid in the sewage are separated, the separated clean water is output through the water outlet, and the sewage residue is output through the sewage outlet. In some settling tanks, a certain amount of sewage is added to the settling tank, and then the sewage can be added after the solid-liquid separation and output, which cannot meet the continuous settlement requirements in the continuous production process, resulting in low sewage treatment efficiency.
