Abstract

The invention relates to an anaerobic granular sludge expanded bed-gravity flow membrane filter sewage treatment system and a method utilizing the same to treat the sewage. The invention relates to a sewage and waste water treatment system and a method utilizing the same to treat the sewage, which aims at solving the problems of the aerobic active sludge process of the existing sewage treatment plant that the energy consumption is high, the floor occupied area is large and the energy recycling is poor. The system consists of a water inlet pipe, a sewage lifting pump, a water inlet valve, a water inlet flow meter, a high-level water tank, a floating ball valve constant-level device, an anaerobic granular sludge expanded bed, a sludge discharging valve, a three-phase separator, an inner cycling pipe, an inner cycling flow meter, an inner cycling pump, a wet-type flow meter, a backflow pipe, a backflow pump, a backflow valve, a backflow flow meter, a constant-level overflowing device, a gravity-flow membrane filter device, a membrane assembly and a water outlet flow meter. The system is low in energy consumption, small in floor occupied area and high in energy recycling capacity. The system is used for treating the domestic sewage and the industrial waste water.

Description

technical field [0001] The invention relates to a waste water treatment system and a method for treating sewage by using the system. Background technique [0002] Most of the sewage treatment plants in my country adopt the aerobic activated sludge process, which consumes a lot of energy and occupies a large area, which is contrary to my country's national conditions of energy conservation, emission reduction and land shortage; at the same time, As the discharge standards of industrial wastewater become more and more stringent, zero discharge of sewage and wastewater has become the goal of various enterprises. Therefore, both municipal sewage and industrial wastewater are facing the problem of improving the quality of sewage effluent and the problem of energy and resource recovery in the process of treatment. Under such national conditions and background, it is of great significance to research and develop new sewage and wastewater treatment processes. Anaerobic biological t...
