Medical wastewater three-stage treatment technique

Abstract

The invention relates to the field of medical wastewater treatment, particularly a medical wastewater three-stage treatment technique which comprises the following steps: a primary macroscopic impurity removal technique is performed, wherein the primary macroscopic impurity removal technique comprises sedimentation tank treatment, precipitation tank treatment and regulating tank treatment, and is used for macroscopic impurity removal; medical wastewater after the primary macroscopic impurity removal technique enters a secondary microscopic impurity removal technique, wherein the secondary microscopic impurity removal technique comprises water softener tank treatment, hydrolysis-acidification tank treatment, aeration biological tank treatment, electrolysis cell treatment and MBR (membrane bioreactor) tank treatment, and is used for microscopic impurity removal; and medical wastewater after the secondary microscopic impurity removal technique enters a tertiary disinfection discharge technique, wherein the tertiary disinfection discharge technique comprises secondary sedimentation tank treatment, disinfection tank treatment and discharge, and is mainly used for sterilizing and disinfecting the wastewater. The technique can remove different pollutants in the medical wastewater by using different treatment processes, and can implement efficient purification on the medical wastewater.

Description

technical field [0001] The invention relates to the field of medical wastewater treatment, in particular to a three-stage treatment process for medical wastewater. Background technique [0002] At present, my country's medical industry is developing vigorously, and medical wastewater is also produced during the development of medical industry. Medical wastewater has complex components, high concentration and salt content, and contains various organic pollutants, radioactive substances and inorganic heavy metal pollutants. etc. If it is not handled properly, the pollution to the environment will be unimaginable, and the treatment of medical wastewater in the existing process still needs to be improved. Therefore, it can be seen from the above problems that people are in urgent need of a new type of Medical wastewater treatment process, that is, a three-stage treatment process for medical wastewater, which removes radioactive elements in medical wastewater by anion-cation exchan...

[0002] At present, my country's medical industry is developing vigorously, and medical wastewater is also produced during the development of medical industry. Medical wastewater has complex components, high concentration and salt content, and contains various organic pollutants, radioactive substances and inorganic heavy metal pollutants. etc. If it is not handled properly, the pollution to the environment will be unimaginable, and the treatment of medical wastewater in the existing process still needs to be improved. Therefore, it can be seen from the above problems that people are in urgent need of a new type of Medical wastewater treatment process, that is, a three-stage treatment process for medical wastewater, which removes radioactive elements in medical wastewater by anion-cation exchange method, completes the removal of organic pollutants with the help of microorganisms, and removes inorganic heavy metal pollutants in wastewater by electrolysis , use the membrane treatment method to clean up the impurities, complete the sterilization and disinfection with the help of strong oxidants, and finally realize the qualified discharge of medical wastewater
