2、 Introduction to Comprehensive Sewage Treatment Equipment in Medical Laboratories

The comprehensive sewage of medical institutions contains some special pollutants, such as drugs, disinfectants, diagnostic agents, detergents, heavy metals, oily wastewater, as well as a large number of pathogenic microorganisms, parasite eggs, and various viruses, such as roundworm eggs, hepatitis viruses, tuberculosis bacteria, and dysentery bacteria. In addition, the wastewater from medical institutions with isotope diagnosis and treatment rooms also contains radioactive substances such as radium-226, phosphorus, gold-198, iodine-131, etc. Shenyang Maixinyu Technology Co., Ltd. has developed the Letep LTP-D series of medical comprehensive sewage treatment equipment based on the high levels of pathogenic bacteria, viruses, insect eggs, chemical agents, and radioactive isotopes in the water quality of medical wastewater. The equipment includes sewage collection tanks, sewage regulation tanks, grilles, cover plates, contact oxidation tanks, biochemical tanks, coagulation air flotation automatic stirring units, coagulation assisted sedimentation reaction units, sedimentation separation units, multi-stage advanced oxidation treatment units, multi-stage decomposition degradation treatment units, multi-stage disinfection treatment and other related treatment processes. The LTP-D series medical comprehensive sewage treatment equipment from Letep is widely used in provincial, municipal, and township medical institutions, as well as disease control centers, animal disease prevention and control centers, and the livestock industry nationwide, and has received high praise from users.

3、 Model selection of comprehensive sewage treatment equipment for medical laboratories

Note: The processing capacity of medical comprehensive sewage treatment equipment can be customized according to the actual needs of users.

4、 Functional characteristics of comprehensive sewage treatment equipment in medical laboratories

1. Widely practical and adaptable to various types of medical comprehensive wastewater treatment;

2. Adopting multiple state-of-the-art patented technologies for multi-stage treatment and purification of wastewater to meet discharge standards;

3. Through centralized control, it has a high degree of automation, simple operation, and fully automatic operation, without the need for dedicated personnel;

4Automatic protection function for water leakage and electric leakageHigh and low pressure automatic protection function, no wastewater protection function, and liquid level protection function of the storage tank;

5Timer automatic cleaning function:The system automatically cleans and flushes the components that need to be cleaned and rinsed at regular intervals, resulting in a longer service life;

6. Dynamic operation, digital LCD display of water quality indicators;

7. Modular integration technology, with good treatment effect, does not produce secondary pollution such as waste residue and wastewater, and has low operating costs;

8. Features such as acid and alkali corrosion resistance, low noise, low power, and multiple safety protections;

9. Through the "one-stop" integrated design, it has a beautiful appearance, small footprint, fast processing speed, low investment, easy installation and movement, large processing capacity, good processing effect, low energy consumption, no noise, no leakage, and is environmentally friendly, truly achieving engineering equipment. No need to dig multiple treatment tanks, no secondary pollution such as waste residue, exhaust gas, and wastewater will be generated;

10PLC programmable intelligent control system, human-machine interface operating system:The system is controlled by a programmable logic controller(PLC)+LCD touch screen+remote control system completes the automatic control and monitoring of the electrical and instrumentation parts. The LCD liquid crystal displays Chinese and has human-machine dialogue function, clock and language setting function. When the equipment is turned on, the electronic control system automatically detects and automatically processes wastewater. For different components and concentrations of wastewater, the control system automatically calculates and then automatically dispenses drugs according to the proportion, which is more scientific and rational. The detailed functions are as follows:

10.1. All operational actions of the equipment can be remotely implemented, such as start stop, flushing, and sewage discharge functions;

10.2. Remote monitoring displays the operating status of each unit, such as animated flowcharts, water tanks, water quality, water pumps, etc;

10.3. When the quality of the produced water is not up to standard, automatic alarm and reflux treatment will be triggered, and tracking records will be kept;

10.4. Equipped with automatic protection for abnormal states such as water, power, and overload, as well as automatic fault alarm and handling functions;

10.5. The system can automatically prompt users to replace relevant components of the host and other internal self check information of the system;

10.6. It can automatically record and manage historical water quality data and analysis, and can be printed as a report;

11Timer power on/off function:The device can set the automatic start-up time in the morning and automatic shutdown time in the evening according to the customer's situation. After setting the time, the device will automatically start and shut down at a scheduled time every morning and evening, eliminating the need for operators to go to the equipment processing room to start and shut down every morning and evening;

12Remote monitoring and operation function (optional):Customers only need to install remote control software in the office or control room through a microcomputer to remotely monitor, operate, and manage the wastewater treatment equipment in the wastewater treatment room, and constantly understand the operation and status of the equipment. It is a legitimate and legitimate software that will not be detected as a virus by antivirus software, and will not affect the stability of the system. It is a completely free remote control software.

12.1Advantages of remote monitoring:

a、 Remote access desktop: Synchronize the viewing of the remote human-machine interface screen, and be able to use the local mouse and keyboard to operate the human-machine interface on the remote device as if operating the local machine.

b、 Remote file management: remotely modify and run files, achieve resource sharing between two ends, and be used for remote work, etc.

c、 Remote command control: remote boot, remote shutdown, remote restart, remote logout, locking local or remote programs, etc.
