Sewage purification device

Abstract

The invention discloses a sewage purification device which comprises a grid tank, a water collection tank, a sand settling tank, a gas dissolving tank and a purification tank. Two grid plates are mounted inside the grid tank, the sand settling tank is mounted at the bottom of the grid tank via support rods and is positioned on a side of a funnel-shaped water guide pipe, a side of the sand settlingtank is connected with the gas dissolving tank by a first water flow pipe, a motor is mounted on the top of the purification tank, fan blades are mounted at an output end of the motor via a rotary shaft, ultraviolet lamps are mounted inside the purification tank, a waste residue collection tank is mounted inside the purification tank and is positioned below the rotary shaft, and the water collection tank is mounted on a side of the purification tank via a second water flow pipe. The sewage purification device has the advantages that grid, sand settling, gas dissolving, purification disinfection and collection can be systematically carried out on sewage by the sewage purification device with a series of structures, cycle treatment can be conveniently carried out on sewage which is not thoroughly treated, and accordingly the sewage can be optimized.

Description

Technical field [0001] The invention relates to the technical field of sewage purification, in particular to a sewage purification device. Background technique [0002] With the development of the economy, people's living standards have improved, and people have higher and higher requirements for the living environment. However, due to the rapid population expansion, it also brings great pressure on urban sewage treatment. The sewage purification equipment currently on the market has poor sewage treatment capacity. The sewage treatment method after sewage purification is improper and the structure is complicated, which is not good for the environment. Protection, with the increasing shortage of water resources, sewage treatment, purification and reuse has become an indispensable and important development direction in economic and social development, and various sewage treatment equipment has been continuously used in the field of wastewater treatment. Due to the wide variety and...

Problems solved by technology

However, due to the rapid expansion of the population, it also brings great pressure on the sewage treatment of the city. The sewage purification equipment currently on the market has poor sewage treatment capacity, and the sewage treatment method after sewage purification is improper, and the structure is complex, which is not conducive to the environment. Protection, with the increasingly tense water resources, sewage treatment, purification and reuse have become an indispensable and important development direction in economic and social development, and various sewage treatment equipment are constantly being used in the field of wastewater treatment

Due to the variety and complex composition of industrial sewage, it is difficult to treat and often requires large-scale treatment equipment. For small factories or households, the existing sewage treatment equipment has a large area, complex equipment, long treatment time or poor treatment effect. , high treatment cost, poor effluent quality, etc.
