（3）After treatment, purified water can be considered for recycling, reducing treatment load, lowering operating costs, improving economic benefits, and saving water;
（4）Newly built sewage treatment facilities are easy to operate and run, with low operating costs;
（5）Laying concealed pipes to avoid large-scale excavation of concrete pavement and to avoid damaging the original greenery in the flower garden area, the original greenery should be restored in place to maintain its original aesthetic effect.

Underground medical wastewater treatment equipment——Ordering instructions

1Due to the fact that the equipment is buried underground, maintenance and upkeep are difficult. Therefore, when designing and manufacturing this equipment, we considered its maintenance free nature and equipped it with inspection holes to facilitate the repair of sudden faults.

2Equipment is generally usedQ235The steel plate is made with ordinary anti-corrosion inside, and the general service life can reach10Years or more.

3The lifting water pump matched with the equipment adopts an anti clogging and tear type submersible pump, which can effectively pass through the diameter30~80mmThe solid particles can tear apart long fiber materials without the need for a filter screen at the inlet of the water pump. Safe operation of water pump8000More than hours. The fan room is set up separately.

4After selecting the device, users only need to connect the power supply of the device, connect the inlet and outlet pipelines of the device, and the pipelines between each individual unit of the device to put it into normal operation.

5If there are special requirements for frozen soil layers in the user's area, they must be specified in the order. In order to adjust the height of the inspection hole according to the thickness of the frozen soil layer in the user's device usage area

Underground medical wastewater treatment equipment——Working principle

WSZThe removal of organic pollutants and ammonia nitrogen by buried domestic sewage treatment equipment mainly depends on theAOBiological treatment process. The working principle is:existADue to the high concentration of organic matter in sewage, microorganisms are in a state of gas deficiency, and at this time, they are facultative microorganisms,They convert and decompose organic nitrogen in wastewater intoNH-N,Simultaneously utilizing organic compounds as electron donors,supportNO-NConvert intoN,And it also utilizes some organic carbon sources andNH-NSynthesize new substance.soAThe graded pool not only has a certain organic matter removal function,Reduce the organic load on subsequent aerobic tanks,To facilitate the process of nitrification,And relying on the high concentration of organic compounds present in the raw water,Complete denitrification process,Ultimately eliminating eutrophication pollution caused by nitrogen,existODue to the significant decrease in organic matter concentration.,But there is still a certain amount of organic matter and highNH-Nexist.In order to further oxidize and decompose organic matter,At the same time, nitrification can proceed smoothly when carbonization is completed,existOSet up aerobic biological contact oxidation tanks with low organic load at different levels,existOThere are mainly aerobic microorganisms and self oxidizing bacteria in the graded pool(nitrobacteria),Aerobic microorganisms decompose organic matter intoCO2andH2O,autotrophic bacteria(nitrobacteria)Utilizing inorganic carbon generated by the decomposition of organic matter or in the airCO2As a source of nourishment,Remove the pollutants from the sewageNH-NConvert intoNO-N..OThe effluent from the cascade pool flows back toALevel pool, forAThe level pool provides electron acceptors through denitrification Ultimately eliminate nitrogen pollution.

Underground medical wastewater treatment equipment——Advantages of integrated sewage treatment equipment

（5）The integrated equipment can be flexibly configured according to the quality of raw water, making it widely applicable.

（6）Probiotics are highly efficient microbial strains. For special wastewater, our company can provide specialized probiotics to quickly and effectively ensure that the effluent quality meets the standard.

Underground medical wastewater treatment equipment——Electrical Control Instructions
The sewage treatment equipment adopts the method from inlet to outletPLCFully automatic control. The specific control content is as follows:
(1)The sewage regulating tank is equipped with a liquid level control device, which operates automatically at high liquid levels; Stop the pump at low liquid level.
(2)The fan operates alternately and provides uninterrupted air supply. Two fans can set the automatic switching interval time as required.
(3)It is recommended to use dual power supply for sewage treatment plants. The main pumps in the processing technology are used alternately, with mutual use and backup, to ensure normal operation.

(4)The start-up, shutdown, and switching of various electrical equipment are automatically linked by a programmable controller according to the program. At the same time, there are automatic and manual transfer switches on the panel of the control cabinet, which can be switched to manual control if necessary.
(5)All types of electrical equipment are equipped with circuit short-circuit and carrier devices, and indicator lights are also installed to display the working status of each electrical equipment.
5Equipment room, operation room
The electrical control cabinet should be installed in the ground building, and it is recommended to arrange it in the water treatment room next to the main sewage treatment structure to facilitate daily operation management and equipment maintenance.
6Anti corrosion measures
In this process, the main equipment is made of steel structure and undergoes deep anti-corrosion treatment. After mechanical rust removal treatment on the inner and outer surfaces
The surface is coated with epoxy coal tar for corrosion prevention. All connecting pipes, fittings, etc. are made usingABSMaterial, capable of withstanding corrosion from acid, alkali, and salt, and others
All steel fittings are coated with epoxy coal tar for corrosion prevention
