Background
In the system of a small and medium-sized water supply plant, if water containing iron and manganese is used as source water, when the two indexes exceed the current national standard of drinking water in China, water treatment links of iron removal and manganese removal are needed. The water treatment scheme adopted at present is a common rapid filter or a siphon filter, and the basic flow is as follows: water source, water guide pipeline, aeration tank, filtering tank, clean water tank, water supply two pumps, etc., wherein the filtering tank and the aeration tank are core process equipment, the whole system has high cost, more structures and large occupied area. No matter what treatment process is adopted, the aeration and oxygenation process is needed to oxygenate and deodorize the source water, and volatile harmful substances in the source water are released at the same time so as to improve the PH value of the source water. The transmission between the water after aeration and the filter tank in the aeration tank is commonly carried out by auxiliary facilities such as a pipeline or an open channel, a valve body and the like, but the pipeline or the open channel is easily blocked by rust mud separated out from the water after aeration and oxygenation, so that the transmission of the water is affected.
In addition, when the two indexes of iron and manganese in the source water are simultaneously higher and reach a certain value, if only primary filtration treatment is adopted, the water quality of the treated water cannot reach the standard, and secondary filtration water treatment is needed. The current common secondary water treatment method is to adopt two sets of basically same existing systems for treatment, and firstly perform iron removal by primary filtration and then perform manganese removal by secondary filtration according to the oxidation activity characteristics of iron and manganese. However, such a secondary water treatment system requires a larger construction land for constructing more buildings, and the filter tanks and the aeration tanks in the two sets of systems are independent bodies, cannot be adjusted mutually due to the change of water quality, can cause larger waste of treatment capacity, has larger investment and longer construction period, and is not suitable for construction and use of medium-sized and small-sized water plants with daily water production of ten thousand tons and less than ten thousand tons.

The treated water enters the primary filtering water outlet manifold 26 through each primary filtering water outlet pipe 7 and flows into the clean water tank 44, so that primary water treatment operation is finished.
The use method of the multi-filtration water treatment condition is as follows.
When the iron and manganese in the source water 43 coexist and the super standard value of the source water and the source water is high, the quality of the secondary filtered water is required to reach the standard. By arranging the secondary filtering lifting pump 28, by means of adjustment and transformation of pipelines and valves and different combinations, one or more filter groups 1 in the system can be used as a primary filter group 1 or a secondary filter group 1 according to the water quality condition of source water through arbitrary combination transformation, so that the aim of removing iron and manganese simultaneously by one system is realized. In this case, the primary filter tank group 1 may be treated with the source water 43 to remove iron, and the secondary filter tank group 1 may be treated with the secondary filter tank group 45 and the secondary filter tank group 48 to remove manganese.
The J15 primary filtration water outlet end total valve 29 is closed to prevent the primary filtration water from entering the clean water tank 44, the J12 primary filtration water valve 10, the J14 primary filtration water valve 10, the J21 secondary filtration water outlet valve 11, the J23 secondary filtration water outlet valve 11 are closed, the J25 secondary filtration water outlet end total valve 31, the J22 secondary filtration water outlet valve 11, the J24 secondary filtration water outlet valve 11, the J11 primary filtration water valve 10, the J13 primary filtration water valve 10, and the J16 primary filtration water outlet initial total valve 27 are opened. The YS1 primary filter inlet valve 17, the YS3 primary filter inlet valve 17, the RC2 secondary filter inlet valve 18, and the RC4 secondary filter inlet valve 18 are opened, and the YS2 primary filter inlet valve 17, the YS4 primary filter inlet valve 17, the RC1 secondary filter inlet valve 18, and the RC3 secondary filter inlet valve 18 are closed.
The source water 43 conveyed by the primary pump station enters the first tank 45 and the third tank 47 through the primary filtering water inlet pipe 15 of the first tank 45 and the primary filtering water inlet pipe 15 of the third tank 47, after aeration and primary filtering are finished, passes through the primary filtering water outlet pipe 7 of the first tank 45 and the primary filtering water outlet pipe 7 of the third tank 47 and the primary filtering water outlet pipe 26, is lifted by the secondary filtering lifting pump 28, enters the second tank 46 and the fourth tank 48 through the secondary filtering water inlet pipe 16 of the second tank 46 and the secondary filtering water inlet pipe 16 of the fourth tank 48, is collected through the secondary filtering water outlet pipe 8 of the second tank 46 and the secondary filtering water outlet pipe 8 of the fourth tank 48 after secondary aeration and filtering, and then passes through the clear water main 36, and the secondary filtered water is conveyed to the clear water tank 44, so that different filtering functions, namely the multifunctional purposes of the independent filter tank 1 in the system are finished.
The backwash operation is as follows.
When the filter tank runs for one period, the filter material needs to be backwashed and regenerated. During backwashing, only a single pond group can be carried out one by one, other filter pond groups 1 can normally operate, and the treated water can be used for backwashing the filter pond and can also normally supply water to the outside.
Taking the backwashing No. two pond 46 as an example, the backwashing state of the No. two pond 46 is changed from the normal operation state, the valve J12 primary filtering water valve 10 and the J22 secondary filtering water outlet valve 11 are closed, the F2 backwashing water inlet valve 6, the P2 backwashing water outlet valve 4, the P5 backwashing water outlet total valve 22 are opened, the YS2 primary filtering water inlet valve 17 and the RC2 secondary filtering water inlet valve 18 are closed, after the work is completed, the backwashing pump 25 is started, and the No. two pond starts backwashing.
The backwash water comes from the clean water tank 44, enters the second tank 46 from the F2 backwash water inlet valve 6 and is discharged from the second tank 46 from the P2 backwash water outlet valve 4. After the back washing is finished, the F2 back washing water inlet valve 6 and the P2 back washing water outlet valve 4 are closed, the back washing pump 25 is closed, the YS2 primary filtering water inlet valve 17 or the RC2 secondary filtering water inlet valve 18 is opened (when the filter tank group is primary filtering, the YS2 primary filtering water inlet valve 17 is opened, and when the filter tank group is secondary filtering, the RC2 secondary filtering water inlet valve 18 is opened), meanwhile, the C2 primary filtering water outlet valve 12 is opened, the primary filtering water after the back washing is discharged, after the water is qualified, the C2 primary filtering water outlet valve is closed, the state before the back washing is recovered, and the second tank 46 is in normal operation after the back washing is finished.
The end of the primary filter intake manifold 34 serves as an overrun line between the water source and the clean water basin.
When the system is built and installed, the filter materials in the filter tank group 1 are filled, the system is required to be debugged before formal use, and the filter materials are required to be backwashed firstly because of more impurities, dust and other substances in the initially-filled filter materials, and then the water treated by the system can enter the clean water tank 44. Since the clean water tank 44 is in a non-water state at the beginning of the adjustment, no clean water is available for backwashing the filter material. At this time, the source water 43 is introduced into the clean water tank 44 by using the end of the primary filter water inlet manifold 34 as an overrun line, and the source water 43 is backwashed by the backwash pump 25. After backwashing of the filter materials, the YS5 once filtering water inlet main valve 35 is closed, the filter tank normally filters, primary filtered water is required to be discharged through the primary filtered water drain pipes 9 of each filter tank group 1, after the treated water of the filter tank group 1 is qualified, the primary filtered water drain pipes 9 are closed, qualified treated water is injected into the clean water tank 44, and after the clean water tank 44 is cleaned and disinfected, the filter tank can be normally used, and the operation is carried out only once before debugging after a system is built.
Another situation in which the primary filter intake manifold 34 is used as an override line is when all filter banks 1 are inoperable during an extreme accident, at which time the YS5 primary filter intake main valve 35 may be opened to introduce source water 43 into the clean water tank 44 as emergency water supply.
