The surface of the aeration plate 29 is distributed with a number of uniform micropores. The water pipe 20 adopts a stainless steel inner polishing structure, which can prevent Impurities are accumulated in the water pipe 20, the ultraviolet sterilizer 17 is a flow-through ultraviolet sterilizer, and the mechanical water filter 11 is a quartz sand filter.

Quartz sand filter belongs to pressure type filter equipment. It uses quartz sand to filter medium. Under certain pressure, the raw liquid passes through the medium, and is intercepted and floated by the pores between the filter materials to achieve the purpose of filtering. The filtered liquid is filtered along the filter. The gaps between the materials flow through, and the impurities are gradually retained. It belongs to membrane filtration, which filters out suspended solids in water, insoluble particles, flocculent sediments and other foreign matters, decolorizes and deodorizes, and the gaps of the filter media play a role in sieving the suspended solids, so that the suspended solids are easy to be trapped in. On the surface of the filter material, when a certain amount of dirt is retained on the surface of the filter material to form a filter membrane, the pressure difference between the front and rear of the filter will increase rapidly over time until it fails. The backwash method is used to trap impurities in the filter layer, Flush out of the filter to restore the original filtering function.

Activated carbon filter 12 and quartz sand are both pressure filter equipment, and their equipment operations and backwashing operations are basically the same. Using activated carbon as a filter medium, under a certain pressure, the raw liquid passes through the activated carbon, and the activated carbon filter material adsorbs the raw water. Pigment, peculiar smell and residual chlorine in the water will escort the next-level RO reverse osmosis system. When the activated carbon is adsorbed for a period of time, it will be saturated and invalid. At this time, the activated carbon needs to be backwashed and the adsorbed dirt can be discharged before continuing to use.

The function of the security filter 13 is to intercept the particles larger than 5 μm leaked from the filter product water and prevent them from entering the reverse osmosis filter chamber 15. Such particles may break down the reverse osmosis membrane 26 components after being accelerated by the high pressure pump 14, resulting in a large amount of leakage. In the case of salt, the impeller of the high-pressure pump 14 is scratched at the same time. The filter element in the filter is a replaceable cartridge filter rod. When the pressure difference between the inlet and outlet of the filter is greater than the set value, it should be replaced.

Reverse osmosis filtration chamber 15: The membrane that is selective for the permeated substances is called a semi-permeable membrane. Generally, a membrane that can only permeate a solvent but cannot permeate a solute is called an ideal semi-permeable membrane. When a solution (such as fresh water) and a concentrated solution (such as salt water) are placed on both sides of a semipermeable membrane, the solvent in the dilute solution will naturally pass through the semipermeable membrane and flow to the concentrated solution side spontaneously, a phenomenon called osmosis. , when the osmosis reaches equilibrium, the liquid level of the concentrated solution will be higher than that of the dilute solution by a certain height, that is, a pressure difference will be formed. This pressure difference is the osmotic pressure. The size of the osmotic pressure depends on the inherent properties of the solution. That is, it is related to the type, concentration and temperature of the concentrated solution and has nothing to do with the properties of the semipermeable membrane. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the flow direction of the solvent will be opposite to the original permeation direction, starting from the concentrated solution. The solution flows to the side of the dilute solution. This process is called reverse osmosis. Reverse osmosis is a reverse migration movement of osmosis. The separation method separated from the solvent has been widely used in the purification and concentration of various liquids. The most common application example is in the water treatment process, using reverse osmosis technology to remove inorganic ions, bacteria, viruses, organic substances in raw water. And impurities such as colloids are removed to obtain high-quality purified water.

Controller 41: According to the engineering characteristics and system configuration of the water treatment station of the water supply project, the system currently uses a conventional electrical linkage control method to control the system, considering that the control system has liquid level, pressure, water quality and reverse osmosis inside and between pumps The reverse osmosis device of the linkage control system is equipped with PLC (programmable controller 41) for programming control to ensure the stability and reliability of the system.

In addition, a data transfer after-sales service system is added to the electronic control system. This system can transfer the specific data of the equipment during operation. Our company will analyze the user in advance according to the response of the data, so as to avoid abnormal operation of the equipment.

The sterilization principle of the ultraviolet sterilizer is to use the energy of ultraviolet photons to destroy the DNA structure of various viruses, bacteria and other pathogenic bodies in the water body, mainly to break various structural bonds in the DNA or to undergo photochemical polymerization, such as making DNA THYMINE dimerizes, so that various viruses, bacteria and other pathogens lose their ability to replicate and reproduce, and achieve the effect of sterilization.
