A sewage treatment device

Abstract

The invention discloses a sewage treatment device. The device comprises a chlorine spraying platform and a chlorine spraying tank arranged on the top of the chlorine spraying platform; a first inner cavity is formed in the position, below the chlorine spraying tank, of the chlorine spraying platform, a first conical wheel is connected to the inner top wall of the first inner cavity in a rotary and matched mode, and a stirring shaft is fixedly arranged on the top of the first conical wheel, wherein the upper extending part of the stirring shaft penetrates the inner top wall of the first inner cavity and is connected with the inner top wall of the first inner cavity in a rotary and matched mode; a second inner cavity extending transversely is formed in the position, below the first inner cavity, of the chlorine spraying platform, a first sliding cavity extending upwards is formed in the extending tail end of the left side of the second inner cavity in a communicated mode, the top extending part of the first sliding cavity is located in the opposite position of the left side of the first inner cavity, and a first rotary shaft extending transversely is connected to the position between the inner wall of the left side of the first inner cavity and the inner wall of the right side of the top extending part of the second inner cavity in a rotary and matched mode. According to the sewage treatment device, the structure is simple, operation is convenient, the service life is long, the automated degree is high, and the working efficiency and quality of chlorine spraying are improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device. Background technique [0002] Industrial production and residents’ daily life will produce a large amount of sewage. If the sewage is directly discharged into creeks and rivers without treatment, it will seriously affect the water quality and environmental landscape. A series of procedures such as alum and chlorination are finally discharged into the river. The traditional method used in China is to use liquid chlorine or take out the chlorine and mix it with water to dissolve the chlorine in the water to form a hypochlorous acid disinfectant, and then put a certain amount of hypochlorous acid into the bacteria-containing sewage through the delivery device to make it interact with the bacteria. In contact with each other, the strong oxidizing property of hypochlorous acid is used to kill bacteria and achieve the purpose of disinfection. The f...

Problems solved by technology

At present, the feeding devices on the market are expensive and have low automation, which increases the chance of contact between people and hypochlorous acid, which is harmful to human health, and water and chlorine are easy to mix unevenly.
