Hackle drum type magnetic separation water treatment facility

Abstract

The invention discloses a hackle drum type magnetic separation water treatment facility, which comprises a water inlet channel, a rotational flow sand settling tank, an air floating tank, a flocculation tank, a magnetic separation tank, and a water outlet; one end of the water inlet channel is connected to a raw water source, the other end is tangentially communicated with the rotational flow sand settling tank through a pipeline or a closed conduit, the pipeline or the closed conduit is inclined, thus the joint between the pipeline / closed conduit and the sand settling tank is higher than the joint between the sand settling tank and the air floating tank; the joint between the air floating tank and the sand settling tank is arranged in the upper part of the tank wall of the air floating tank, the joint between the air floating tank and the flocculation tank is arranged in the bottom of the tank wall of the air floating tank, an aeration device is arranged in the air floating tank; a roller type magnetic separator is arranged in the magnetic separation tank, and comprises a hackle annular cylinder, a fixing shaft, a magnet, and a bearing, and the hackle annular cylinder is fixed above the magnetic separation tank through the bearing. The provided water treatment facility has the advantages that better effluent effect is guaranteed, the kinetic energy of water flow is fully utilized, and the energy consumption for water treatment is largely reduced.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a magnetic separation treatment device. Background technique [0002] With the acceleration of China’s urbanization and industrialization, the discharge of domestic sewage and industrial wastewater is increasing. The discharge of sewage to the environment has led to the deterioration of water quality in natural water bodies. In recent years, the total discharge of sewage in my country has shown an increasing trend year by year, and the water environment has deteriorated. The contradiction between the rising standards of the people's demand and China's demand has become increasingly prominent, and the pollution of water resources is very serious. Magnetic separation water treatment technology has been recognized by the market for its efficient and fast water treatment effects. However, the existing magnetic separation water treatment devices still have some shortcomings. For example, the...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing sewage treatment device cannot effectively remove sand and flocs, and the requirements for the device are relatively high, the energy consumption is large, the water quality of the effluent is not high, and the effect of the effluent is not good. Comb-tooth drum type magnetic separation water treatment device that reduces the energy consumption necessary for the water treatment device, further improves the effluent water quality of the device, and ensures a better water effluent effect
