Multi-functional medical wastewater treatment equipment of disconnect-type
Technical Field
The invention relates to the technical field of laboratory wastewater treatment, in particular to a separated multifunctional medical wastewater treatment device.
Background
Medical wastewater refers to wastewater from medical institutions containing some harmful substances such as drug residues, pathogens, chemical substances, etc. Because of their high pollution and hazard, they must be subjected to rigorous treatments to meet emission standards.
Because medical wastewater has the characteristics of wide sources, a large number of pathogenic bacteria, viruses and chemical agents, complex components, acid, alkali, suspended solids, COD, chemical agents, heavy metals and other substances, and toxicity and harm, compared with the common domestic sewage treatment, the medical wastewater often needs to be subjected to special process treatment so as to prevent the bacteria from diffusing and spreading through the sewage.
The existing medical wastewater treatment process generally comprises three steps of pretreatment, biological treatment and chemical treatment, wherein the pretreatment mainly aims at removing suspended matters, sediment, sludge and the like in wastewater, a physical precipitation or mechanical filtration method is generally adopted, the biological treatment is a process of converting organic matters in wastewater into inorganic matters through microorganisms, the chemical treatment is a process of killing pathogens in wastewater or decomposing organic matters in wastewater by utilizing chemical matters, and in the actual treatment process, the treatment process is reasonably selected according to sources and components of wastewater, for example, a process of 'pretreatment-first-stage strengthening treatment-disinfection' can be adopted for comprehensive medical (without an infectious ward) wastewater treatment. The particles carrying viruses and germs are removed through coagulating sedimentation (filtration), so that the disinfection effect is improved, the consumption of disinfectant is reduced, and the adverse effect on the environment caused by excessive consumption of disinfectant is avoided.
Professional wastewater treatment equipment is required for treatment of medical wastewater, but the existing wastewater treatment equipment has the following problems when used for treatment of medical wastewater:
1. firstly, in the physical treatment part, the filtering speed is low and the treatment efficiency is low due to the poor filterability of the filter screen. In particular, most of the existing wastewater treatment devices still adopt a large number of fixed filter screen filtration modes when removing suspended matters and sediments in wastewater and separating coagulated sediments of soluble matters, and the mode is commonly used for treating domestic sewage, but is difficult to be applied to medical wastewater containing a large amount of suspended sediments, especially when the medical wastewater is subjected to sedimentation treatment, a coagulant is further required to be added, partial solid impurities are generated after the coagulant reacts, the influence of turbidity of the medical wastewater is caused, the liquid part in the wastewater is difficult to quickly pass through a filter screen, the filtration time is increased, the filtration efficiency is low, and the filter screen holes are easy to be blocked due to long-time accumulation of original sediments and newly formed sediments in the wastewater, so that the treatment efficiency is lower.
2. Secondly, in the chemical treatment part, various treating agents react with medical wastewater insufficiently, so that the treatment is not thorough. Specifically, in the process of mixing and reacting medical wastewater with a treatment agent, the problem of accumulation of the treatment agent is easy to occur due to poor fluidity of the wastewater, so that the treatment agent is in insufficient contact with the wastewater, and the reaction is slow.
3. Finally, after the wastewater treatment is completely finished, the problem that solid impurities and sediments in the treatment device are inconvenient to clean is solved. Specifically, a large amount of solid impurities are left in the treatment device after precipitation and filtration, one part of the solid impurities are original suspended matters and particulate matters in medical wastewater, the other part of the solid impurities are newly generated precipitates after flocculation, and the impurities are accumulated in the device for a long time to cause the blocking of filter holes, so that the treatment efficiency is reduced, and therefore, the conventional wastewater treatment device is required to be cleaned regularly, is complicated to disassemble and clean and has a large range of cleaning dead angles.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
