The invention relates to the technical field of filtering, and discloses a filtering control system. The filtering control system comprises a filtering system, a washing system connected with the filtering system, and an air-blowing system connected with the filtering system; the filtering system comprises a filtering device; an inlet of the filtering device is connected with a raw liquid inlet section, and an outlet of the filtering device is connected with a filter liquid outlet section; the washing system comprises a washing liquid inlet section connected with the inlet and/or the outlet ofthe filtering device; the air-blowing system comprises an air exhausting section arranged on the filtering device and a blowback air inlet section connected with the filter liquid outlet section; control valves are connected with the raw liquid unlet section, the filtered liquid outlet section, the washing liquid inlet section, the air exhausting section and the blowback air inlet section. The filtering control device is high in automation degree, reduces labor intensity of operators, and saves operation time. The nickel electrolysis system is bad in environment, a medium has corrosivity, sothat by adopting the filtering control system, it is avoided that due to the fact that an operator directly makes contact with the corrosive medium, the body is injured, and the operation environmentis improved; in addition, manual misoperation can be avoided.
