Abstract

The invention discloses a medical wastewater treatment method which comprises the following steps: S1, arranging multiple layers of non-balance plasma jet flow stimulator on a jet flow purifier; S2, supplying power to each high-voltage electrode through a plasma power supply; S3, controlling a gas flow control valve a and a gas flow control valve b to be opened by a valve opening degree electroniccontroller; S4, controlling a liquid flow control valve to be opened by a valve opening degree electronic controller, and feeding a liquid to be treated in a liquid storage tank into an action spaceof array non-balance plasma jet flows; S5, under the action of the non-balance plasma jet flow, killing a target purification substance in liquid droplet granules in an atomization field; S6, collecting liquid spray purified by the array non-balance plasma jet flows in a water treatment tank; and S7, opening a detection hole control valve, pumping out a liquid after purification by using a detection hole refluxing pump, and feeding the liquid into a detection unit. The non-balance plasma technique has the characteristics of being high in killing efficiency, low in pathogene regeneration rate,low in use cost, and the like, and is a completely new efficient and clean water purification technique.

Description

technical field [0001] The invention relates to a method for treating medical wastewater. Background technique [0002] At present, the source and composition of hospital sewage are complex and harmful. The main source is the sewage discharged from the hospital's diagnosis and treatment rooms, laboratories, wards, laundry rooms, X-ray photography rooms and operating rooms. Sewage contains a large number of pathogenic bacteria, viruses and agents, and has the characteristics of space pollution, acute infection and latent infection. If hospital sewage containing pathogenic microorganisms is discharged into urban sewers or environmental water bodies without disinfection treatment, it will often cause water pollution, cause various diseases and infectious diseases, and seriously endanger people's health. When non-equilibrium plasma technology is used to treat medical wastewater, the liquid flow rate is too small due to the small size of the ionization space (that is, the apertu...
