The bottom of the scum separating chamber is provided with a first sludge discharge pipe, the top is provided with a scum collecting tank, and the scum collecting tank is connected to a scum discharge pipe. The side wall of the scum separating chamber is provided with a water distribution pipe, the end in the scum separating chamber of the water distribution pipe is arranged on the bottom of the scum separating chamber, the leading-out end is connected to the leading-out tank of a reaction chamber, and the opening end of the leading-out tank is arranged on the bottom of the reaction chamber. A precipitation area is arranged in the reaction chamber, a leading-out chamber is arranged in the precipitation area, the bottom is provided with a slope; the bottom of the leading-out chamber is connected to a filter device containing a filter membrane through a second water pipe, and the water outlet end of the filter device is connected to a water outlet pipe. The leading-out chamber is connected to a water pump through a connection water pipe, the water outlet end of the water pump is connected to the top end of a dynamic pipe, and the bottom end of the dynamic pipe is connected to an impeller.

Description

technical field [0001] The invention relates to a sewage treatment equipment, which is suitable for domestic sewage, hospital waste water, etc., and in particular relates to a sewage treatment equipment which uses a filter membrane to purify oily waste water. Background technique [0002] With the development of industry, especially the development of petrochemical industry, the discharge of oily wastewater is increasing day by day, and its pollution to the environment is also becoming more and more serious. Oil in oily wastewater mainly exists in the form of floating oil, dispersed oil, emulsified oil, dissolved oil and oil-solids, and there are other pollutants in wastewater. At present, the methods for treating oily wastewater mainly include air flotation, centrifugal separation, and biological methods. These methods have the disadvantages of high energy consumption and high operating costs. Contents of the invention [0003] In view of the above-mentioned defects ...
