The invention relates to water treatment equipment and particularly relates to a novel metal film filter. The novel metal film filter comprises a tank body, wherein the tank body is internally provided with a filtering water inlet pipeline, a backwashing water outlet pipeline, a filtering water outlet pipeline and a backwashing water inlet pipeline from top to bottom; the lower side of a skirt support is connected with a blowdown pipeline; a water distributor is arranged at the top in the tank body; a filtering water inlet connected with the water distributor is arranged at the outer part of the tank body; a filtering water outlet is arranged on the right side of the filtering water outlet pipeline; a liquid gathering pipe and a liquid collection pipe are arranged on the filtering water outlet pipeline; and the metal film is suspended and mounted in the tank body through taking the central line of the filter as the axis in a radial-parallel and vertical layering manner. The novel metal film filter is not easy to break; a film filtering gap is stable and the power consumption of filtering and backwashing power equipment is low, the daily maintenance cost is low and the sewage treatment cost is low; and the requirements of three-grade filtering phase indexes of petroleum and petrochemical oil-containing sewage, production wastewater of industrial and mining enterprises, municipal sewage and household drinking water are stably met.
