Comprehensive sewage treatment device

Abstract

The invention discloses a sewage comprehensive treatment device, comprising a treatment box, the inside of the treatment box is separated from left to right by a partition into a stirring and crushing cavity, a sediment cavity and a dissolved air cavity connected in sequence, and the left upper end of the treatment box is A sewage inlet pipe connected to the stirring and crushing chamber is provided; a stirring device is provided in the stirring and crushing chamber, and a stirring motor is provided at the upper end of the treatment tank to drive the stirring device to rotate; a horizontally arranged filter screen is provided at the lower end of the sediment chamber The left side of the lower end of the dissolved air chamber is provided with a dissolved air nozzle, and the dissolved air nozzle communicates with an external dissolved air tank, and the right side of the described dissolved air nozzle is provided with a plurality of ultrasonic generators at intervals, and the upper end of the described dissolved air chamber is provided with There is an air flotation processing mechanism. The invention has reasonable structural design and convenient use, can realize effective treatment of sewage in small medical institutions through stirring and pulverizing, sedimentation, air flotation treatment and multiple disinfection treatment of sewage, has high treatment efficiency, good treatment effect and strong practicability.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage comprehensive treatment device. Background technique [0002] Most of the existing medical sewage disinfection equipment uses chlorine dioxide generators, because chlorine dioxide disinfection needs to stay for more than 1 hour, first of all, a large disinfection pool is needed, and many small clinics are located above the second floor, and do not have the ability to dig disinfection pool condition. The raw materials of chlorine dioxide are hydrochloric acid and sodium chlorate. Among them, hydrochloric acid is a key dangerous product under the control of the Public Security Bureau. It needs to be applied for procurement, and the procedure is cumbersome. In addition, it is inconvenient to store, has a pungent smell and strong corrosion; sodium chlorate is unstable, When mixed with phosphorus, sulfur and organic matter and impacted, it is prone to combustion and explosion...

[0002] Most of the existing medical sewage disinfection equipment uses chlorine dioxide generators, because chlorine dioxide disinfection needs to stay for more than 1 hour, first of all, a large disinfection pool is needed, and many small clinics are located above the second floor, and do not have the ability to dig disinfection pool condition

The raw materials of chlorine dioxide are hydrochloric acid and sodium chlorate. Among them, hydrochloric acid is a key dangerous product under the control of the Public Security Bureau. It needs to be applied for procurement, and the procedure is cumbersome. In addition, it is inconvenient to store, has a pungent smell and strong corrosion; sodium chlorate is unstable, When mixed with phosphorus, sulfur and organic matter and impacted, it is prone to combustion and explosion, easy to absorb moisture and agglomerate, poisonous

Although the disinfection effect is good, it requires high installation conditions and inconvenient management
