Embodiment 1

[0083] A general hospital in Beijing produces 600t / day of mixed medical and domestic wastewater, and the influent water quality is shown in Table 1:

[0084] Table 1 Influent water quality data of embodiment 1 of the present invention

[0085]

[0086] The treatment process is as follows:

[0087] The waste water from the administrative building, outpatient building and inpatient building of the hospital is directly discharged to waste water pool 1 through the sewage well to obtain hospital sewage A.

[0088] Wastewater tank 1 carries out aeration treatment:

[0089] Blowing air into hospital sewage A can make water and air fully contact to exchange gaseous substances and remove volatile substances in water; at the same time, this process increases dissolved oxygen in wastewater, so that microorganisms in water can play a role in oxidation of some organic substances.

[0090] The hospital sewage A is aerated through the waste water tank 1 to uniform the water quality and ...

Embodiment 2

[0117] The hospital sewage A described in embodiment 1 is processed using the same process as in embodiment 1, the difference is:

[0118] The dosage of nano-magnetic seeds is 0.08% of the mass of mixed solution B, the dosage of PAC is 0.019% of the mass of mixed solution B, and FeCl is also added 3 , PAC with FeCl 3 The mass ratio is 10:9, the dosage of PAM is 0.0005% of the mass of the mixed solution B, and the mixed solution C is obtained.

[0119] ClO 2 disinfect:

[0120] The ClO 2 The dosage of the solution is 0.0032% of the solution G mass.

[0121] Results of hospital wastewater treatment:

[0122] After the above treatment process, the water quality of the produced water is shown in Table 3:

[0123] Table 3 The water quality data of the embodiment 2 of the present invention

[0124]

[0125] Finally, the effluent from the clear water pool 6 meets the "Discharge Standards of Water Pollutants for Medical Institutions" (GB18466-2005) and "Comprehensive Dischar...

Embodiment 3

[0127] The hospital sewage A described in embodiment 1 is processed using the same process as in embodiment 1, the difference is:

[0128] Magnetic loading coagulation reaction:

[0129] The dosage of nano-magnetic seeds is 0.08% of the mass of mixed solution B, the dosage of PAC is 0.016% of the mass of mixed solution B, and FeCl is also added 3 , PAC with FeCl 3 The mass ratio is 5:3, the dosage of PAM is 0.0005% of the mass of the mixed solution B, and the mixed solution C is obtained.

[0130] Results of hospital wastewater treatment:

[0131] After the above treatment process, the water quality of the produced water is shown in Table 4:

[0132] Table 4 Example 3 of the present invention water quality data

[0133]

[0134]

[0135] Finally, the effluent from the clear water pool 6 meets the "Discharge Standards of Water Pollutants for Medical Institutions" (GB18466-2005) and "Comprehensive Discharge Standards for Water Pollution of Beijing Local Standards" (DB1...

Abstract

The invention provides a hospital sewage treatment integrated device and method. The hospital sewage treatment integrated device comprises a wastewater pool, a flocculation device, a super magnetic separation device, an ultrafiltration device, an activated carbon adsorption device and a clean water pool, all of which are connected in sequence. The hospital sewage treatment integrated device is simple in structure and small in occupied area. Hospital sewage is treated through the devices in sequence, required stay time is short, and the hospital sewage can be efficiently and quickly treated. The hospital sewage treatment method is simple in process, liquid passes through the wastewater pool, the flocculation device, the super magnetic separation device, the ultrafiltration device, the activated carbon adsorption device and the clean water pool in sequence, the stay time of the liquid in each device is short, and the treatment efficiency is high. A physical method is adopted for water treatment in the ultrafiltration device and the activated carbon adsorption device, no chemical agent needs to be added, the influence of environmental factors is small, raw materials are easy to obtain, and practical application is convenient.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an integrated device and method for hospital sewage treatment. Background technique [0002] Hospital sewage refers to the sewage discharged from hospitals (general hospitals, professional hospitals and other types of hospitals) to the natural environment or urban pipelines. Its water quality varies with the nature, size and area of ​​different hospitals. The main pollutants contained in hospital sewage are: pathogens (parasite eggs, pathogenic bacteria, viruses, etc.), organic matter, floating and suspended matter, radioactive pollutants, etc. The total amount of bacteria contained in untreated raw sewage reaches 10^8 Individuals / mL or more. [0003] At present, the common treatment methods for hospital sewage in China are biochemical methods, mainly oxidation ditch, activated sludge and MBR. However, as we all know, the biochemical sewage treatment method is slo...
