Problems solved by technology

Its shortcomings are: (1) The treatment process is unreasonable; pathogenic microorganisms are often treated in the last step, causing pathogenic microorganisms to easily remain in the previous device, causing secondary pollution to the subsequent batch of medical wastewater, and increasing Risk of spread of pathogenic microorganisms
(2) High-temperature sterilization and filter sterilization cannot effectively kill various bacteria and viruses in medical wastewater, and the effect is not ideal

Embodiment 1

[0040] The present embodiment provides a treatment system for medical wastewater, which includes a disinfection tank 3, a regulating tank 4, a redox tank 5, an anaerobic tank 6, an aerobic tank 7, a flocculation sedimentation tank 8 and a sludge tank 9 connected in sequence, The water inlet pipe 1 is connected to the disinfection tank 3, and the water outlet pipe 2 is connected to the flocculation sedimentation tank 8.

[0041] Disinfectant pool 3 is provided with disinfectant storage device 31, is stored with disinfectant in disinfection pool storage device 31, and the disinfectant used in the present invention is chemical disinfectant, as chlorine dioxide, ozone, any one in potassium hydrogen persulfate kind. Disinfection tank 3 is connected with regulating tank 4 through valve 32 , and the surface area of ​​valve 32 is large enough so that all materials in the regulating tank enter disinfection tank 4 .

[0042] A grid 41 is arranged in the regulating tank 4 to filter larg...

Embodiment 2

[0047] This embodiment provides a new type of sewage flocculant, which is a pullulan-polyacrylamide graft polymer. The flocculant has large particles, fast settling speed, and branches, which can capture multiple suspensions from different directions. Particles to obtain larger flocs, thereby effectively reducing the COD of medical wastewater. The sewage flocculant is prepared through the following steps:

[0048] Step 1: disperse amylopectin in water to form a 0.1-0.2 g / mL amylopectin solution. Take cerium nitrate according to the ratio of 3-4:50 according to the mass ratio of cerium nitrate and pullulan, and dissolve in water to form a saturated solution, add the saturated solution of cerium nitrate in the pullulan solution; 400-600r / min, Heat in a water bath at 45-55°C for 5-10min.

[0049] Step 2: Weigh acrylamide according to the mass ratio of acrylamide to pullulan as 2:3-5, disperse it in water, heat to dissolve, and add the pullulan solution at a uniform speed of 1-2...

Abstract

The invention discloses a system for treating medical wastewater, which relates to the field of medical wastewater treatment. The system for treating medical waste water of the present invention comprises water inlet pipe, water outlet pipe and the disinfecting pond connected in sequence, adjustment pond, redox pond, anaerobic pond, aerobic pond, flocculation sedimentation pond and sludge pond; Described water inlet pipe is connected to In the disinfection tank, the outlet pipe is connected to the flocculation sedimentation tank, and the adjustment tank is provided with a material pipeline connected to the sludge tank. The system disinfection pool for treating medical wastewater provided by the present invention is set before other treatment pools, and the medical wastewater is first sterilized to prevent pathogenic microorganisms in the medical wastewater from diffusing in the subsequent device during the treatment process and affecting the next batch of medical treatment. Wastewater causes secondary pollution and reduces the risk of pathogenic microorganisms spreading; chemical methods are used to kill pathogenic microorganisms, and the disinfection effect is good.

Description

technical field [0001] The invention relates to the field of medical wastewater treatment, in particular to a system for treating medical wastewater. Background technique [0002] With the vigorous development of my country's medical industry, the amount of medical wastewater is also increasing. Medical wastewater is mainly discharged from medical consultation rooms, laboratories, wards, laundry rooms and operating rooms, and its sources and components are very complex. Hospital wastewater contains a large number of pathogenic bacteria, viruses, chemical agents and heavy metal ions, such as drugs, disinfectants, diagnostic agents, detergents, as well as a large number of pathogenic microorganisms, parasite eggs and various viruses, such as roundworm eggs, hepatitis Viruses, Mycobacterium tuberculosis and Shigella etc. It has the characteristics of space pollution, acute infection and latent infection. Compared with industrial wastewater and domestic wastewater, it has the...
