Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, in particular to a device for collecting, purifying and treating waste liquid for medical examination. Background Art

[0002] Medical testing is a medical tool used to evaluate and diagnose diseases. It conducts laboratory tests and analyses on body samples such as blood, urine, and tissues to obtain information about the patient's health status, disease diagnosis, condition monitoring, and treatment effect evaluation. It can help doctors make precise diagnoses, assess the severity of the disease, develop treatment plans, and monitor the effectiveness of treatment. It plays a vital role in clinical medicine and is of great significance for the early detection, diagnosis, and treatment of diseases.

[0003] The laboratory waste mainly comes from specimens such as blood, urine, stool, sputum, disposable items such as plastics and glass, and waste liquid discharged from chemical reagents and instruments during the experiment. The waste liquid and waste discarded by hospital laboratories mostly contain pathogens, bacteria and harmful components. In order to prevent the waste liquid from polluting the environment and spreading diseases, it is generally stored in a container and purified by precipitation, or by adding strong oxidants (such as ozone, hydrogen peroxide, chlorine dioxide, etc.) to gradually degrade the organic matter in the waste liquid into simple inorganic matter, or oxidize the pollutants dissolved in water into substances that are insoluble in water and easy to separate from the water.

[0004] The current purification treatment method generally pre-treats the test waste liquid by filtering to reduce the impact on the subsequent oxidation process, and then introduces an oxidizing solvent for mixing, and uses stirring to improve the treatment effect and efficiency.

[0044] Then, every time the filter disc 603 is about to take out the intermediate product or sediment, the connecting block 701 can be inserted into the card slot 610 and the connecting block 701 can be driven to rise, so that the blocking ring 704 can be driven to rise synchronously during the rising process of the connecting block 701 to release the blocking of the through groove 12 by the blocking ring 704.
