A low-energy membrane ozone air flotation integrated device, including an ozone air flotation cylinder, a contact cylinder and a membrane module are arranged in the ozone air flotation cylinder, wherein the contact cylinder and the ozone air flotation cylinder are coaxial And lower than the ozone air floating column, the top of the contact column is open, the bottom is connected with the raw water tank and the dosing box, the contact column is the contact area, and the membrane module is arranged at the lower water outlet of the ozone air floating column , the height of the membrane module is lower than the height of the contact cylinder, and the water in the ozone air column passes through the membrane module and then drains out. Draining outward, the invention can solve the problem of high energy consumption in combination of ozone air flotation and membrane filtration process, realize the integration of ozone air flotation-membrane filtration process and minimize the occupied area, and at the same time ensure the treatment effect of the process.
Description
technical field [0001] The invention belongs to the technical field of advanced sewage treatment, and in particular relates to a low energy consumption membrane ozone air flotation integrated device. Background technique [0002] As an advanced treatment process for urban sewage, the ozone flotation process has the characteristics of good organic matter and chroma removal effect, short residence time, and small footprint. However, the suspended solids in the effluent of the pure ozone air flotation process are difficult to meet the requirements for reuse. The filtration process will well control the turbidity of the effluent. However, the membrane filtration process requires a high-pressure pump for suction, which greatly increases the energy consumption of the treatment process and significantly increases the treatment cost. Therefore, in view of the above problems, it is necessary to develop a low-energy membrane ozone flotation integrated device, which is of great signi...
