Sewage treatment equipment

Abstract

The invention discloses sewage treatment equipment, and relates to the technical field of sewage treatment. The sewage treatment equipment includes a cylinder. The side wall of the cylinder is provided with a water inlet, a water outlet and a feed inlet. A motor is fixedly mounted on the cylinder. The inside of the cylinder is also provided with a stirring assembly, an aeration assembly and a feeding assembly. The stirring assembly in the invention stirs sewage in different directions. Moreover, the aeration assembly can rotate according to the rotation of a rotating plate, which increases an aeration range. The feeding assembly realizes intermittent switch of the feed inlet through the rotation of the rotating plate, and so a material can be placed in the cylinder at equal time intervals. The aeration assembly and the stirring assembly cooperate to make the contact between the sewage and air fuller and make the mixing more uniform. The feeding assembly and the stirring assembly cooperate to make the contact between the material and the sewage fuller, and so the dissolution rate of the material is fast, which improves the treatment effect of the sewage. Moreover, the aeration assembly and the feeding assembly in the device does not need to be additionally provided with a driving device, which reduces the cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment. Background technique [0002] The random discharge of sewage will have a great negative impact on the environment. Therefore, sewage needs to be treated before it is discharged. In the existing sewage treatment, people often use aeration tanks to treat sewage. Through aeration, the air and water are strongly Contact, dissolve the oxygen in the air into the water, and add regulating materials to the sewage to treat various substances in the water body. At the same time, in order to treat sewage efficiently, the stirring component is used to stir the sewage to accelerate the interaction between the regulating material and various substances in the sewage. rate, the aeration range of the existing aeration device is fixed, the mixing of sewage and air is not sufficient, the aeration efficiency is low, and it is difficult to meet the increasing dem...

[0002] The random discharge of sewage will have a great negative impact on the environment. Therefore, sewage needs to be treated before it is discharged. In the existing sewage treatment, people often use aeration tanks to treat sewage. Through aeration, the air and water are strongly Contact, dissolve the oxygen in the air into the water, and add regulating materials to the sewage to treat various substances in the water body. At the same time, in order to treat sewage efficiently, the stirring component is used to stir the sewage to accelerate the interaction between the regulating material and various substances in the sewage. rate, the aeration range of the existing aeration device is fixed, the mixing of sewage and air is not sufficient, the aeration efficiency is low, and it is difficult to meet the increasing demand for sewage treatment. At the same time, the traditional stirring components for stirring sewage and materials, stirring blade They all rotate in one direction, and the efficiency of the stirring plate is low. If you rely on the continuous reverse rotation of the motor, the service life of the motor will be reduced, and in the process of putting in the adjusting material, a large amount of adjusting material is usually added manually or mechanically at one time. , and then stirred. In this process, the dissolution rate of the regulating material is slow, which may easily cause excessive addition of the regulating material, causing new pollutants to be regenerated in the sewage and reducing the treatment effect of the sewage.
