Abstract

The present invention relates to the field of water treatment, and provides a vertical sewage treatment device. The vertical sewage treatment device comprises: a shell (7), wherein the bottom of shellis connected with a water inlet device and a sludge discharge pipe (3); a first flow guide cylinder (4) and the second flow guide cylinder (6), which are vertically arranged in the shell in sequencefrom inside to outside, wherein the second flow guide cylinder is provided with a bottom which has a sectional area decreases progressively, and a plurality of sludge return pipes (11) and a cavity allowing space the inside and the outside the bottom of the second flow guide cylinder to communicate with each other are also arranged at the bottom; a flow guide cover (5), which is arranged between the first flow guide cylinder and the second flow guide cylinder, wherein intervals are formed among the first flow guide cylinder, the flow guide cover and the second flow guide cylinder; and a waterinlet device, wherein after the water inlet device is sequentially connected with the bottom of the shell and the bottom of the second guide cylinder, a nozzle (1) located at an upper end is close toor extends into the bottom of the first flow guide cylinder to spray water upwards, and the sectional area of an opening in the bottom of the first flow guide cylinder is larger than the outer diameter of the nozzle, so fluid is allowed to enter the first flow guide cylinder from the bottom. The device can reduce the dosage of chemicals, lower energy consumption and decrease an occupied area.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a vertical sewage treatment device. Background technique [0002] my country's water resources are relatively tight. With the acceleration of urbanization and industrialization in our country, the discharge of waste water in the country has also increased year by year, resulting in continuous deterioration of natural water bodies, and the situation of water resource pollution is still very serious. Water pollution and water shortage have become serious constraints to the sustainable development of my country's economy and society. In recent years, the country has continuously increased its emphasis on and support for the environmental protection industry, and the sewage treatment industry has also developed rapidly. Especially in the field of water treatment, environmental protection equipment has the characteristics of small footprint, flexible application range, small investment...
