The invention relates to a kind of new integrated negative pressure continuous-film filtering system. It selects n (1<n<100) negative pressure membrane module set by paralleling for use, and connects them by the water line in order to constitute a membrane module unit; in both sides of each membrane module unit, there is a control valve for producing water and back washing in each side, which connects separately with the producing water pump or the back washing pump. That selecting n (1<n<100) negative pressure membrane module unit by connecting in parallel can constitute a (m*n) type integrated negative pressure filtering system with the continuous membrane. The invention conquers the disadvantages that the existing filtering system with continuous membrane has complex system, high energy consumption, high investment cost, non-realization of leak hunting on-line and so on. While simplifying the control system, it can decline the investment and the operating cost, so it improves the flexibility of system manipulation and has the obvious economic benefits and environment benefits in practical application.
