Abstract
The invention relates to an integrated coagulation and direct-filtration filter cloth reactor for urban sewage recycling pretreatment, and belongs to the technical field of water treatment equipment. The reactor mainly comprises a box-type tank body, a water inlet coagulation chamber, a concentrated mud bucket, and a rotatable filter cloth assembly and self-cleaning equipment which are arranged in the box-type tank body; the rotatable filter cloth assembly consists of fiber filter cloth, a turntable framework, a hollow water outlet shaft and a transmission motor; and the self-cleaning equipment consists of a self-cleaning cloth water nozzle, a self-cleaning reflux pipe and a flushing pump. According to the reactor, urban sewage is directly separated through a dynamic filter cloth membrane technology, organic carbon sources in the sewage are effectively concentrated, and energy is recovered by using an anaerobic technology; by combining a coagulation technology, membrane pollution rate is retarded, and energy consumption is reduced; and pretreatment is provided for a subsequent process, so that the treatment load of the subsequent process is lightened.
Description
technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to an integrated coagulation direct filter cloth reactor for resourceful pretreatment of urban sewage. Background technique [0002] In recent years, the rapid growth of China's economic level and population has led to a substantial increase in urban sewage production. The current mainstream urban sewage activated sludge treatment process includes main structures such as grit chamber, primary sedimentation tank, aeration tank and secondary sedimentation tank. The main body uses the aerobic activated sludge in the aeration tank to remove organic The decomposition and transformation of pollutants can obtain better effluent water quality, but it also has high energy consumption, large structures, and CO 2 The defect of large emissions gradually fails to meet the requirements of the concept of sustainable development in today's climate change and resource ...
