Sewage treatment device

Abstract

The invention discloses a sewage treatment device, which comprises a liquid storage bin, a filter plate is arranged on the liquid storage bin, and a liquid inlet bin is arranged on the filter plate; one side of the filter plate is arranged on the liquid storage bin through a rotating shaft, and the rotating shaft is connected with a Motor, the side wall of the liquid inlet bin is provided with a slag outlet at the rotating shaft; the liquid inlet bin is provided with a liquid inlet pipe; the bottom of the liquid storage bin is provided with an agitator, and the side of the liquid storage bin is provided with The liquid outlet pipe and the dosing mechanism, the liquid outlet pipe is provided with a liquid outlet pump; it also includes a plurality of slag scraping units arranged side by side above the filter plate, one end of the plurality of slag scraping units is connected by a connecting rod, and the connecting rod is provided with There is a push rod, and a long rod is hinged on the push rod, and a short rod is connected to the long rod, and the short rod is connected to a motor; The slag plate, the two ends of the slag scraping rod are fixed on the filter plate through the guide seat. The invention performs pre-filtering to ensure the reaction effect; it can also accurately control the amount of dosing and avoid waste of materials.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment device which integrates filtering, dosing and slag scraping. Background technique [0002] With the country's economic development and modernization process, various types of environmental pollution are increasingly affecting our lives, especially water pollution is the number one threat. In order to control the pollution of sewage to the environment, sewage is now concentrated in sewage treatment plants for comprehensive treatment to meet the discharge standards stipulated by the state. [0003] During the treatment of sewage, it is necessary to add chemical solution for reaction treatment. However, at present, the chemical treatment is directly carried out in the sewage tank, and there are the following problems: 1. The sewage has not been pre-treated. Since the sewage contains a large amount of particulate matter, direct chemical injection will Affect the reacti...

[0003] During the treatment of sewage, it is necessary to add chemical solution for reaction treatment. However, at present, the chemical treatment is directly carried out in the sewage tank, and there are the following problems: 1. The sewage has not been pre-treated. Since the sewage contains a large amount of particulate matter, direct chemical injection will Affect the reaction efficiency; 2. Generally, the workers do the medicine manually, and the dosage cannot be controlled, resulting in waste of materials
