Ultrasonic catalytic membrane distillation medical wastewater treatment system

Abstract

The invention discloses an ultrasonic catalytic membrane distillation medical wastewater treatment system which comprises a water inlet tank, the water inlet tank is communicated with a water inlet of a first sewage pump, a water outlet of the first sewage pump is communicated with a waste liquid heating tank, and the waste liquid heating tank is heated through a solar heating system. The waste liquid heating tank is communicated with a water inlet of a second sewage pump and a water outlet of a hot-side circulating pump, the water outlet of the second sewage pump is communicated with the upper part of the side surface of the ultrasonic catalytic membrane distillation reaction tank, the lower part of the side surface of the ultrasonic catalytic membrane distillation reaction tank is communicated with a water inlet of the hot-side circulating pump, and the upper part of the ultrasonic catalytic membrane distillation reaction tank is communicated with a clean water tank; the clean water tank is communicated with a clean water storage tank and a water inlet of a cold side circulating pump, a water outlet of the cold side circulating pump is connected with a water inlet of a condenser, and a water outlet of the condenser is communicated with the lower part of the ultrasonic catalytic membrane distillation reaction tank. The ultrasonic catalytic membrane distillation medical wastewater treatment system can solve the current problem that the application is limited due to the turbidity of waste liquid in the photocatalysis process, and the service life of the distillation membrane is prolonged.

Description

technical field [0001] The invention relates to an ultrasonic catalytic membrane distillation medical wastewater treatment system, which belongs to the technical field of advanced treatment of sewage and wastewater. Background technique [0002] Medical wastewater is mainly sewage discharged from various departments of the hospital. The source and composition of the sewage are very complex, containing a large number of pathogenic bacteria, viruses, chemical agents, heavy metals, especially some refractory organic substances, such as antibiotics, etc., which have space pollution, The characteristics of acute infection and latent infection, if not handled properly, will cause serious water environment, soil environment pollution, and even cause various diseases, or lead to the outbreak of water-borne infectious diseases. [0003] The disposal principles of medical wastewater are the whole process control principle, the reduction principle, the local treatment principle, the cl...
