8. A circulating water filtration system according to claim 5, characterized in that the control system (12) employs a DCS control system.
9. A circulating water filtration system as claimed in claim 5, wherein,
the alarm system (13) is an audible and visual alarm system.
10. A method of circulating water filtration comprising the steps of:
s1, a circulating water inlet flows to a manganese sand filtering unit (1) through a three-way valve, flows into a descaling unit (2) after being filtered by the manganese sand filtering unit (1), performs preliminary floating object filtering and calcium magnesium ion electrochemical filtering, and a first online detection unit (11) detects floating objects and calcium magnesium ion residues and reports the floating objects and the calcium magnesium ion residues to a control system (12);
s2, filtering the circulating water filtered in the step S1 in a backwashing system (3), and carrying out real-time sewage disposal through a sewage disposal system of the backwashing system (3) in the running process regularly;
s3, circulating water filtered in the step S2 flows to a security filter (4), fine filtration is carried out, water sample particles and bacterial indexes are detected by a second line detection unit (12), and the water sample particles and bacterial indexes are reported to a control system;
s4, flowing the circulating water filtered in the step S3 to an ultra-filter (5) for purification and filtration, detecting the PH value and organic matter residues of a water sample by a drainage third online detection unit (13), and reporting to a control system;
s5, quantitatively feeding the filtered circulating water in the step S4 with a control system signal through an automatic adjusting and dosing device to adjust the PH value and sterilize; then is discharged by a drain valve (7);
s6, monitoring the water outlet flux by using a flowmeter and reporting to a control system;
s7, maintaining the non-operating manganese sand filtering unit (1) and the descaling unit (2) for later use.
