Sewage Filtration Dosing Device

Abstract

The invention belongs to environmental protection machinery, in particular to sewage treatment equipment, specifically to a sewage filtering and dosing device, including a medicine mud mixing agitator, a stirring shaft is arranged in the medicine mud mixing agitator, and is connected to the entrance of the medicine mud mixing agitator There is a sludge pump, and the outlet of the medicine sludge mixing agitator is connected to the sludge dewatering equipment. The mixing shaft is provided with a medicine injection inlet and a medicine outlet, and the medicine injection inlet is connected with a medicine feeder and a high-pressure injection system. The present invention uses a high-pressure spraying system to spray the medicine into the medicine sludge mixing agitator, and through the stirring of the stirring shaft, the medicine can be fully mixed into the sludge, which helps to strengthen the particle surface adsorption water and capillary channels in the sludge. The bound water in the sewage is converted into free water and external water, and the toxic and harmful substances in the sewage are fixed in the network chain formed by solidification, so that it can be transformed into a solid similar to soil or with a stronger bond strength, which can make the dehydrated sludge The moisture content can be reduced by more than ten percentage points.

Description

technical field [0001] The invention belongs to environmental protection machinery, in particular to sewage treatment equipment, in particular to a sewage filtering and dosing device. 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. The sewage filtering and dosing system involved in the present invention is the last link in the sewage treatment project, that is, medicine dilution, medicine mud mixing, physical and chemical reaction, mechanical stirring and transportation, etc., and then enters the pressing and dehydration process. In the existing technology, the traditional flocculant is stirred, d...
