The chemical cleaning cycle for cleaning the filtration membrane module 32 of the membrane filtration facility 30 and the cleaning cycle of the ozone supplied to the ozone contact facility 40 are determined according to the water quality of the raw water measured by the measurement means 10 And the backwash cycle of the activated carbon in the activated carbon contact facility 50 is regulated by the control means 20. [

The control means 20 sets the water pollution degree value of any raw water to the measuring means and if the raw water contamination degree measured by the measuring means 10 is higher than the predetermined water pollution degree, The chemical cleaning cycle for cleaning the module 32 is adjusted to increase the input amount of the chemical cleaning liquid.

Also, the ozone contact time is increased in the ozone contact facility 40 to increase the amount of ozone introduced, and the backwash cycle of the activated carbon in the activated carbon contact facility 50 is increased.

Therefore, it is possible to selectively apply the water according to the water quality of the raw water, thereby providing a water treatment function which is stable and improved in efficiency even under changing water quality conditions.

The membrane filtration apparatus 30 includes a raw water supply pump 31 connected to a raw water tank 1 in which raw water to be treated is stored to transfer stored raw water, And a filtration membrane module 32 for filtering the solid particles in the raw water after flowing the raw water conveyed in the raw water.

And an air pump 33 for injecting air into the filtration membrane module 32 to perform air cleaning of the filtration membrane module 32. The dilution and storage of the chemical solution to be introduced into the filtration membrane module 32 And a chemical tank 34 made up of a chemical tank.

When the water level of the raw water is measured to be higher than the water quality level set by the measuring means 10 by the control means 20, the chemical washing liquid stored in the chemical tank 34 is supplied to the filtration membrane module 32, And a membrane filtration production water tank 36 in which the raw water treated in the filtration membrane module 32 is stored.

Here, the chemical cleaning solution is a chemical method such as dissolution and decomposition of adhering matter as a means for restoring the performance of the filter membrane module 32 when the filter membrane module 32 is contaminated by an organic substance or an inorganic substance and the membrane filtering function is deteriorated.

That is, when the water pollution degree of the raw water is measured to be higher than the water pollution degree set by the measuring means 10 by the control means 20, the amount of the chemical washing liquid is increased by the chemical washing pump 35.

The filtration membrane module 32 is a pressurized filtration system in which a filtration membrane is mounted on a pressure vessel and raw water is pressurized through a raw water supply pump 31. The raw water is supplied to the outside of the filtration membrane module 32, To be discharged.

The detailed configuration of the ozone contact facility 40 is such that ozone is generated using liquid oxygen and nitrogen as raw materials and the generated ozone is supplied to the dissolution main pipe 42 to be described later and is controlled by the control means 20 And an ozone generator 41 for increasing the amount of ozone supplied by adjusting the time of ozone injection when the water quality of the raw water is measured to be higher than the water pollution degree.

The raw water conveyed in the membrane filtration production water tank 36 of the membrane filtration facility 30 and the ozone generated in the ozone generator 41 are injected through the ejector and the nozzle respectively to dissolve ozone in the raw water to generate ozone water And a main pipe 42 is included.

The detailed form of the activated carbon contact facility (50) is as follows. The activated carbon contact facility (50) is made of a water tank and has adsorbent paper filled with activated carbon, so that raw water treated in the ozone contact facility is passed and adsorbed on the activated carbon And the activated carbon adsorption paper 51 is removed.

In addition, backwash water and backwash air are introduced into the activated carbon adsorption paper and backwashed to the bottom of the activated carbon adsorption paper (51) to allow the foreign matter adsorbed on the activated carbon to float on the activated carbon adsorption paper. The control means (20) And a backwash pump (52) whose backwash cycle is controlled by increasing the backwash cycle when the water pollution degree is measured to be higher than the set water pollution degree.

(53) for discharging suspended foreign substances when backwash is performed by the backwash pump (52), and a discharge water tank (53) for collectively storing the foreign substances discharged by the backwashing / collecting means (53) 54).

And a filtration storage tank 55 through which the raw water passed through activated carbon in the activated carbon adsorption paper 51 is discharged and stored.

Accordingly, the ozone contact facility 40 removes the substances causing taste and odors, and removes the remaining substances from the activated carbon contact facility 50, thereby achieving more effective water treatment.

Meanwhile, the measuring means 10 comprises a TDS sensor 11. The TDS sensor 11 measures TDS (Total Dissolved Solids) to determine the quality of the raw water in advance, Processing can be performed quickly and precisely so as to be able to cope with the quality of the raw water measured by the TDS sensor 11 in the process and the activated carbon contact process.

2, the measuring means 10 can be used in combination of the TDS sensor 11 and the dissolved oxygen measuring device 12. This can be achieved by measuring the total dissolved solids (TDS) Since the water quality can not be grasped completely, DO (Dissolved Oxygen) of the raw water is also measured so that the water quality of the raw water can be precisely measured.

At this time, the raw water supply pump 31 is divided into first and second raw water supply pumps 31a and 31b, and the numerical value of the total dissolved solids (TDS) of the raw water is measured through the TDS sensor 11 The total amount of the total dissolved solids (TDS) of the raw water is measured by the TDS sensor 11 through the first raw water supply pump 31a to the membrane filtration facility 30. If the TDS (Total Dissolved Solids) The water contamination degree of the raw water is once again measured by the dissolved oxygen measuring device 12 through the supply pumps 31a and 31b and then measured by the dissolved oxygen measuring device 12 to be higher than the set value, The chemical cleaning cycle for cleaning the filter membrane module 32 of the activated carbon contact facility 50 and the ozone injection time in the ozone contact facility 40 and the backwash cycle of the activated carbon in the activated carbon contact facility 50 are increased.

Therefore, the TDS sensor 11 and the dissolved oxygen measuring device 12 can measure the contamination of the raw water or the water quality state more precisely, thereby increasing the processing capacity, improving the quality of the treated water, and facilitating the automation of the water treatment apparatus And further, the unmanned automatic operation of the water purification facility becomes possible.

To this end, the first and second valves 15 and 16 are respectively provided for controlling the opening and closing of the deforming pipe 13 through the control of the disconnected pipe 13 and the opening / closing control means 14 connected to the TDS sensor 11 do.
