Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon sewage treatment equipment, in particular to an activated carbon adsorption type sewage treatment device. Background Art

[0002] Activated carbon adsorption sewage treatment device is a common sewage treatment equipment, which uses activated carbon to adsorb and remove organic matter and pollutants in water to purify sewage. The following are the basic working principles and main components of activated carbon adsorption sewage treatment device:

[0003] Working principle: After the sewage enters the treatment device, it first passes through the pretreatment unit for preliminary filtration and removal of large particle impurities.

[0004] The pre-treated sewage enters the activated carbon adsorption unit, which contains activated carbon filler. The porous structure and large surface area of ​​activated carbon enable it to efficiently adsorb pollutants such as organic matter, pigments, odor substances, heavy metal ions, etc. in the water.

[0005] During the adsorption process, pollutants in the sewage are adsorbed by activated carbon onto its surface or pores, thereby reducing the concentration of pollutants in the sewage.

[0006] The clean water after activated carbon adsorption flows out of the device and enters the subsequent treatment unit or is directly discharged to achieve the purpose of purifying water quality.

[0007] Main components: Pretreatment unit: including screens, desanders, deoilers, etc., used to preliminarily remove large particle impurities and suspended matter in sewage.

[0008] Activated carbon adsorption unit: includes activated carbon filler, filter material layer, filter medium, etc., used to adsorb organic matter and pollutants in sewage.

[0009] Control system: includes water pumps, valves, sensors, monitors, etc., which are used to control the operation of sewage treatment equipment, monitor water quality and adjust treatment parameters.

[0010] Discharge unit: includes clean water collection tank, clean water pump, etc., used to collect and discharge clean water after activated carbon adsorption treatment.

[0011] It can effectively remove pollutants such as organic matter, odorous substances, pigments and heavy metal ions in sewage. Activated carbon has high adsorption performance and regeneration, and can be used multiple times to reduce operating costs. The equipment has a simple structure and is easy to operate and maintain. It is suitable for small sewage treatment sites and temporary sewage treatment needs.

[0012] After long-term operation, the activated carbon adsorption treatment equipment needs to be cleaned or cleaned inside to prevent impurities from remaining inside and affecting the activated carbon adsorption treatment performance. Usually, a cleaning pipeline is connected to transport the cleaning liquid flow to achieve the cleaning of the internal tank, but the current pipeline design is relatively simple and cannot effectively ensure the comprehensive cleaning of the tank.

After the sewage enters the tank body through the liquid inlet pipe, it is adsorbed and filtered by the activated carbon component and then flows out from the liquid outlet pipe;
