With the increasing number of dental clinics, oral medical wastewater has gradually become a serious environmental problem. The traditional wastewater treatment method has poor treatment effect on oral wastewater, and cannot completely remove the harmful substances in it, which has a certain impact on the environment and human health. Therefore, the development of an efficient oral sewage treatment equipment is of great significance for environmental protection and health.
Oral sewage treatment equipment is a kind of equipment specializing in the treatment of oral medical wastewater, and its main principle is to remove harmful substances in wastewater through physical, chemical and biological means. It is mainly composed of multiple parts such as pretreatment system, biochemical reaction system, precipitation system, membrane separation system, etc., each part has different functions.
The pretreatment system is the first process of oral sewage treatment equipment, and its main role is to remove large particulate matter and suspended solids in wastewater to reduce the burden of the subsequent treatment system. The pretreatment system includes a grid, a grit remover, a conditioning tank, etc. The grid can screen out the large particulate matter and suspended solids in the wastewater, the grit tank can precipitate the sediment in the wastewater, and the regulating tank can carry out preliminary adjustment and balance of the wastewater.
The biochemical reaction system is the core part of the oral sewage treatment equipment, which mainly uses biologically activated sludge to remove harmful substances from wastewater. The biochemical reaction system includes two parts: aerobic zone and anaerobic zone, in which the aerobic zone mainly removes organic substances, and the anaerobic zone mainly removes inorganic substances such as nitrogen and phosphorus. Through the treatment of biochemical reaction system, the pollutants in the wastewater can be effectively removed, and the sludge can also be effectively treated.
The sedimentation system is the third process of oral sewage treatment equipment, and its main function is to precipitate the suspended solids and sludge in the wastewater. The sedimentation system includes sedimentation tank, aeration tank, etc., in which the aeration tank can increase the oxygen in the wastewater and promote the sedimentation of sludge.
The membrane separation system is the last process of oral sewage treatment equipment, and its main function is to separate the treated water by membrane, remove the tiny particles and harmful substances in it, and obtain high-quality clean water. The membrane separation system includes ultrafilter, reverse osmosis, etc., where the ultrafilter can remove particulate matter in the water, and the reverse osmosis can remove dissolved substances in the water.
In general, oral sewage treatment equipment is an efficient, environmentally friendly and energy-saving treatment equipment, which can effectively remove harmful substances in oral medical wastewater and reduce the impact on the environment and human health. In the future development, oral sewage treatment equipment will be more widely used to make greater contributions to environmental protection and human health.
