Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically an integrated intelligent recycling system for wastewater treatment. Background Technology
[0002] With the rapid development of the healthcare industry, hospitals are expanding and the number of patients is constantly increasing, leading to a surge in the volume of hospital wastewater. Hospital wastewater is extremely complex, containing not only large amounts of pathogenic microorganisms such as bacteria, viruses, and parasites, but also drugs and their metabolites, heavy metals, chemical agents, radioactive substances, and patient excrement. If this wastewater is discharged directly without effective treatment, it will become a significant source of disease transmission, seriously threatening the ecological environment and public health.
[0003] Traditional hospital wastewater treatment technologies have significant drawbacks. For example, the traditional activated sludge process requires a large area, posing a challenge for hospitals with limited land resources; the treatment process is cumbersome, requiring multiple treatment units and complex equipment, increasing management difficulty and operating costs; moreover, it is poorly adaptable to changes in water quality and quantity. Significant fluctuations in wastewater composition or volume drastically reduce treatment effectiveness, making it difficult to consistently meet discharge standards. While chemical disinfection methods offer significant disinfection effects, they easily generate disinfection byproducts such as trihalomethanes. These substances pose carcinogenic, teratogenic, and mutagenic risks, creating potential threats to the environment and human health. To address these issues, this invention designs an integrated intelligent recycling system for wastewater treatment. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This invention utilizes a filter box to filter impurities from wastewater. A flow meter and output pump work together to transport wastewater from the left end to the right end, achieving automation. Through the synergistic effect of multi-stage biochemical treatment and electrocatalytic advanced oxidation, this system significantly improves the removal efficiency of various pollutants in hospital wastewater. It avoids the disinfection byproducts produced by chemical disinfection methods, reducing secondary pollution to the environment. The system adopts an integrated design, occupies a small area, and can be modularly assembled and flexibly arranged according to the actual needs of hospitals, making it suitable for hospitals of different sizes and reducing infrastructure investment. The system operates stably, is easy to maintain, has a long service life, and low overall operating costs, demonstrating good economic benefits and significant potential for widespread application.
[0012] This invention's anaerobic tank utilizes anaerobic bacteria to decompose large-molecule organic pollutants into small-molecule organic acids, improving the biodegradability of wastewater. The supply of solutions from sodium hydroxide and sodium bicarbonate tanks alters the pH level within the anaerobic tank, providing metabolic substrates for the anaerobic bacteria, increasing the production of small-molecule organic acids, and further improving wastewater biodegradability, thereby enhancing wastewater treatment efficiency and ensuring treatment effectiveness. In the anoxic tank, denitrifying bacteria utilize organic matter in the wastewater as a carbon source to reduce nitrate nitrogen to nitrogen gas, achieving… Nitrogen removal is achieved by supplying ferric chloride solution to the anoxic tank, which acts as a coenzyme factor for microorganisms and enhances the activity of denitrifying enzymes. The methanol solution tank also increases the denitrification rate by supplying methanol solution to the anoxic tank. In the aerobic tank, a large number of aerobic microorganisms proliferate, thoroughly oxidizing and decomposing small-molecule organic matter. At the same time, polyphosphate-accumulating bacteria excessively absorb phosphorus, achieving phosphorus removal. Under the action of an electric field, the electrodes of the electrocatalytic advanced oxidizer generate strong oxidizing substances such as hydroxyl radicals. These free radicals can non-selectively oxidize and degrade the residual recalcitrant organic pollutants in the wastewater, thereby ensuring the pollution removal effect.
[0013] This invention uses the telescopic movement of the sealing plate's moving rod to move the connecting strip, which in turn causes the sealing plate to open and close. This allows control over the aeration rate in the anaerobic, anoxic, and aerobic tanks, ensuring reaction efficiency. Simultaneously, the stirring motor drives the stirring plate to rotate, achieving stirring and further improving the decontamination effect. Attached Figure Description
