Small scale medical wastewater treatment device

The integrated sewage treatment equipment brings convenience to everyone, and the sewage will be discharged after being treated by the equipment It will reduce pollution to daily life, enhance environmental protection, and after sewage treatment, the green environment around us will become more beautiful. The air quality will also be improved to a certain extent, and the environment we breathe in will become fresher, bringing only infinite pleasure and comfort to people. So this is the benefit brought by integrated sewage treatment equipment. The use of integrated sewage treatment equipment not only brings convenience to people's daily lives, but also greatly benefits the overall living environment.

Small scale medical wastewater treatment device——Overview

The buried integrated sewage treatment equipment adopts carbon steel anti-corrosion and high-end technologyUPVCThe glass fiber reinforced plastic structure is made of rectangular shape, which has the characteristics of acid and alkali corrosion resistance, aging resistance, high compressive strength and long service life. It adopts the world's advanced biological treatment technology to collect and removeBODTheCODTheNH3-NAll in one, it is currently an efficient sewage treatment equipment. The treated effluent can meet the national comprehensive sewage discharge standardsGB8978-1996The first level.

Small scale medical wastewater treatment device——working principle

WSZThe integrated domestic sewage treatment system mainly relies onWSZThe efficient removal rate of the process,WSZThe process is to use the sequencing batch activated sludge method(SBR)The anti straight pool is divided into two parts along the length direction, the front part is the biological selection zone, also known as the pre reaction zone, and the rear part is the main reaction zone+A movable and adjustable decanting device has been installed at the rear of the main reaction zone, achieving a cyclic operation of continuous water intake and intermittent drainage, integrating aeration, sedimentation, and drainage.WSZCraftsmanship is aerobic/hypoxia/The process of anaerobic alternating operation has a certain denitrification and phosphorus removal effect. The wastewater operates in a push flow manner, while each reaction zone operates in a completely mixed form to achieve synchronous nitrification denitrification and biological phosphorus removal.

For general sewage,WSZThe process does not require a high degree of pretreatment, only coarse and fine grids and sedimentation tanks need to be set up, without the need for primary and secondary sedimentation tanks, nor does it require a large sludge return system(onlyWSZInside the reactor, there are approximately20%Sludge reflux).

Small scale medical wastewater treatment device——Process flow description:

A.equalization tank

Due to the low elevation of the incoming water, it is not possible to directly flow into the underground hospital sewage treatment equipment. Therefore, an additional water collection and lifting pool will be added in front of the biochemical integration equipment. There are two submersible lift pumps installed in the water collection lifting pool, which lift the wastewater in the pool to the integrated sewage treatment equipment. (The outlet elevation of the regulating pool in this sewage treatment plant exceeds that of the integrated hospital sewage treatment equipment. There is no equipment to lift the regulating pool pump, and the regulating pool sewage flows into the integrated hospital sewage treatment equipment by itself.)

Ｂ.Biological contact oxidation tank (including primary and secondary oxygen tanks)

In the biological contact oxidation tank, oxygen is continuously supplied to the sewage through an underwater aerator, and aerobic microorganisms are used to oxidize organic matter in the sewageCODTheBODGreatly reduced, After reaching the emission standards.

C.sedimentation tank

After biochemical treatment, the sewage enters the sedimentation tank, and the suspended solids in the sewage partially settle at the bottom of the tank. The clarified sewage flows out from the overflow weir at the other end of the sedimentation tank. The sludge accumulated in the sedimentation tank is returned to the contact oxidation tank through the sludge pump.

D.disinfection pool

The disinfection tank receives overflow water from the sedimentation tank. Sodium hypochlorite solution is added to the disinfection tank to kill toxic and harmful microorganisms such as Escherichia coli that remain in the treated water, ensuring the safety of the effluent.

E.Sodium hypochlorite dosing device

The sodium hypochlorite dosing device consists of a metering pump and a dosing bucket, which contains sodium hypochlorite disinfectant. The metering pump continuously and evenly adds disinfectant to the disinfection tank.

Small scale medical wastewater treatment device——Precautions for civil engineering, water intake, drainage, reuse of water, and electrical connection (on-site inspection precautions)

Civil Engineering: Civil Engineering Platform: Long*wide*thick=(Equipment Manager)+400mm）*(Equipment width)+400mm）*200mm

Note: The platform does not require reinforcement, depth=equipment height-100mmThe demand party shall construct their own sludge regulating tank, with a minimum construction volume of24Hourly water storage capacity.

Inlet and outlet: The demand side shall arrange the inlet and outlet water pipelines reasonably.

Reclaimed water: The treated water is discharged to designated locations or recycled according to the regulations of the water quality source and relevant departments.

Power on: Connect380VIndustrial power supply to equipment backup.

Precautions for on-site inspection: Try to place the equipment in areas with less human activity, such as flower beds!

personnel training

Planned training for production operation and management personnel is an important method to ensure smooth operation and improve management level. Our company is responsible for providing free training for technical personnel to users.

（1）Pre training

Training format: Adopting a centralized class format, with our professional personnel (including process, mechanical equipment, and electrical) providing on-site explanations to the operators of the wastewater treatment station.

（2）Post training

After the sewage treatment plant is put into operation, during the commissioning period, we will arrange personnel to work in shifts with the other party's employees to further deepen the training content during the commissioning process, so that employees can have a deep understanding of various training contents.
