With continued reference to fig. 2, the first outlet tube 130 may branch off to a free outlet 1003 for draining water before the centrifugal pump 150.

Because the turbidity of the tap water is unstable and the turbidity of the tap water is influenced by seasonal changes and factors of manual dosing, the turbidity change coefficient of the tap water is large, and the quartz sand filter material is arranged in the multi-medium filter 210, the turbidity of the water can be effectively reduced. Wherein the quartz sand filter material is 4-60 mesh quartz filter material, and the multi-medium filter 210 is made of SUS304 material. And the multi-medium filter 210 is internally provided with a reasonable upper and lower water distribution system, so that the multi-medium filter has the advantages of more uniform water distribution and more stable water quality of the outlet water compared with other filters, and meanwhile, the water flux of equipment is ensured.

As shown in fig. 2 and 3, the tap water from the raw water tank 110 is introduced into the multi-medium filter 210 through the first outlet pipe 130 and the second inlet pipe 220 in order by the centrifugal pump 140, and then is supplied to the softening filter module 300 through the second outlet pipe 230. During backwashing, the valve of the second inlet pipe 220 communicated with the multimedia filter 210 is closed, the valve on the second backwashing pipe 240 is opened, so that tap water introduced from the second inlet pipe 220 enters the second outlet pipe 230 through the second backwashing pipe 240, is introduced from the multimedia filter 210 through the second outlet pipe 230, passes through the multimedia filter 210 from bottom to top, and can be discharged through the second extension pipe 223 and/or the multimedia drain pipe 211 to complete backwashing operation.

When the multi-medium filter is backwashed, the surface filtering layer and the filter membrane are damaged, so that the filtering effect is obviously reduced, and the filter membrane is formed by low-flow-rate operation after backwashed.

Pressure gauges 1001 may be disposed on the second inlet pipe 220 and the second outlet pipe 230, respectively, to display the operating pressure of the multimedia filter 210 and the pressure difference between the inlet water and the outlet water, respectively. The back washing of the multi-medium filter is determined according to the water inlet and outlet pressure difference or the water outlet turbidity/SDI (silt density index), when the water inlet and outlet pressure difference reaches 0.05MPa, back washing is carried out by the front tap water, and when the turbidity is more than 1 degree/SDI and is more than or equal to 5, the back washing strength of the filter is reduced, and the back washing strength of the filter water is 15L/m ² S, a gas-water scrubbing method is adopted under the condition, wherein the gas-water scrubbing method refers to gas-water alternate scrubbing, and the backwashing expansion rate of the filter material is 40% preferably.

The multi-medium filter adopts automatic operation and automatic back flushing, and the back flushing period and time of the filter can be set according to the operation condition of equipment.

As shown in fig. 1 and 4, after the tap water passes through the activated carbon filter module 400, the tap water needs to pass through a reverse osmosis system to remove bacteria, heavy metals and other impurities in the tap water, wherein the reverse osmosis system is mainly implemented by using an RO membrane, and the tap water has high hardness and is easy to scale on the RO membrane, so that the normal operation of the reverse osmosis system is affected. Therefore, the softening filter module 300 is used for replacing calcium and magnesium ions in water to reduce the hardness of the water, so that the RO membrane is not easy to scale and the reverse osmosis system is protected to normally operate.

Specifically, ion exchange resin is provided in the softening filter 310 to replace calcium and magnesium in water. The softening thereof is far from:

2RNa+Ca(HCO3)2/CaCO3/CaSO4＝R2Ca+2NaHCO3/Na2CO3/NaSO4

tap water filtered by the multi-medium filter module 200 passes through a controller valve cavity under a certain pressure (0.2-0.6 Mpa) and flow, is introduced into the softening filter 310 filled with the ion exchange resin through the third inlet pipe 320, na+ contained in the resin exchanges with cations (Ca2+, mg2+, fe2+ … … and the like) in water, and is discharged from the third outlet pipe 330, so that the content of Ca2+, mg2+ ions in the water discharged from the softening filter 310 reaches a set requirement, and the softening of hard water is realized. The total hardness standard of the effluent is less than or equal to 0.03mmol/L.

Similarly, the third washing pipe 340 is opened to allow water to enter the softening filter 310 from the second outlet pipe 330, pass through the softening filter 310 from bottom to top, and then be discharged through the third extension pipe 323 and/or the softening drain pipe 311, thereby completing the backwashing operation. After the backwashing resin fails, before regeneration, the backwashing is carried out from bottom to top by water, and the backwashing has two purposes, namely, the backwashing is carried out to loosen a resin layer pressed in operation, which is beneficial to the full contact of resin particles and regeneration liquid, and firstly, suspended matters accumulated on the surface of the resin and crushed resin are discharged along with the backwashing water, so that the water flow resistance cannot be increased.

As shown in fig. 4, the softening filter module 300 further includes a regeneration salt absorbing passage 350, and the regeneration salt passage 350 communicates with the third inlet pipe 320. The end of the regenerated salt absorbing passage 350 is provided with a salt box interface 351 for connecting with a salt box, so that the salt solution introduced from the regenerated salt absorbing passage 350 enters the softening filter 310 through the third inlet pipe 320 and flows through the failed ion exchange resin to restore the original exchange capacity. With continued reference to fig. 4, a pump may be provided between the regenerated salt absorbing passage 350 and the third inlet pipe 320 to allow the brine to flow through the spent ion exchange resin at a concentration and flow rate. The purpose of the forward washing (quick washing) is to clear the residual regenerated waste liquid in the resin layer, and the resin layer is usually washed at a normal flow rate until the effluent is qualified. Thus, the ion exchange resin does not need to be manually replaced, and the regenerated salt absorbing channel 350 is only opened, so that the automation degree is high.

After the regeneration liquid is replaced, the salt liquid which does not participate in regeneration exchange is still in the softening filter, and clean water with the flow rate smaller than or equal to that of the regeneration liquid is adopted for cleaning, namely slow cleaning, so that the regeneration effect of the salt liquid is fully utilized and the positive cleaning combination is relieved.

The fourth inlet pipe 420 and the fourth outlet pipe 430 are respectively provided with a pressure gauge 1001, which can respectively display the operating pressure of the softening filter module 300 and the pressure difference of inlet water and outlet water. The back washing of the softening filter module 300 is determined according to the water inlet pressure difference, when the water inlet pressure difference reaches 0.05MPa, the back washing of the filter is carried out by a back washing water pump, the filter material replacement period of the activated carbon filter is determined according to the residual chlorine content of the outlet water which is less than or equal to 0.1PPM and the organic matter content CODcr which is less than 1.5mg/L, and the outlet water quality is required to be monitored periodically.

The fourth backwash pipe 440 is opened to allow water to enter the activated carbon filter 4100 from the fourth outlet pipe 430, pass through the activated carbon filter 410 from bottom to top, and then be discharged from the fourth extension pipe 423 and/or the activated carbon drain pipe 411 to complete the backwash operation.

The activated carbon filter adopts automatic operation and automatic back flushing, and the back flushing period and time of the filter can be set according to the operation condition of equipment. Operating flow rate: 11m/h.

As shown in fig. 5, the fourth outlet pipe 430 may be connected to a sampling valve 1004 for sampling the effluent to detect the residual chlorine content of the water. Similarly, the second outlet pipe 230 and the third outlet pipe 330 may be respectively connected to the sampling valve 1004, refer to fig. 3 and fig. 4, so as to detect water condition, and determine whether to enter the next module by controlling the opening and closing of the valves.
