[0002] With the development of various industries, environmental protection has become an important concern of society, and water pollution problems have attracted much attention. Most of the current sewage treatment processes use MBR membrane process. MBR membrane can purify and treat sewage in a biological reactor through the filtration and separation effect of the membrane wire, effectively intercepting suspended solids, colloids and most organic matter and microorganisms in the sewage, and realizing the separation of impurities and clean water in the sewage.

[0003] However, the pore size of the MBR membrane is relatively large, and it is difficult to effectively intercept some small-molecule organic matter, such as part of the organic chemical raw material residue, low-molecular-weight organic acids, alcohol substances, and small microorganisms such as viruses and nanoscale bacteria. These substances can pass through the MBR membrane into the treated water, thereby reducing the effect of water purification treatment and having obvious deficiencies. CONTENT OF THE INVENTION

[0007] By adopting the technical scheme, first, the sewage is introduced into the water purification tank, and then the water pump is started, the water pump forms a negative pressure environment inside the water pump, the water cavity, the first water pipe and the MBR membrane, under the driving of the negative pressure suction, the sewage is smoothly sucked into the MBR membrane, by virtue of the filtering and separating function of the MBR membrane, the suspended solids, colloids and most of the organic matters and microorganisms in the sewage are effectively intercepted, and preliminary filtration is realized; the water body after preliminary filtration is sequentially passed through the first water pipe, the water cavity and the water pump under the action of the pressure difference and finally enters the plurality of RO water purification pipes, the RO water purification pipe performs deep purification on the water treated by the MBR membrane by means of the reverse osmosis principle, accurately intercepts the pollutants such as small-molecule organic matters and tiny microorganisms which are difficult to be removed by the MBR membrane, successfully prevents these impurities from entering the final water body, and by combining the MBR and RO purification processes, the removal rate of various pollutants in the sewage is greatly improved, thereby the overall sewage purification effect is significantly improved.

[0008] Optionally, the top wall of the water purification tank is provided with a driving assembly, the driving assembly comprises a double-shaft motor arranged on the water purification tank, both output ends of the double-shaft motor are provided with eccentric turntables, the eccentric turntables are hinged with connecting rods, the ends of the connecting rods away from the eccentric turntables are hinged with guide rods, and opposite side walls of the water tank are both provided with guide rails, and the guide rods are slidingly arranged in the guide rails.

[0009] By adopting the above technical scheme, in the process of MBR purification of water body, the double-shaft motor drives the eccentric turntables at both ends to rotate, the rotary motion of the eccentric turntables is transmitted to the reciprocating linear sliding of the guide rods in the guide rails through the connecting rods, the motion of the guide rods drives the membrane frame to reciprocate along the length direction of the guide rail, and the inertial force generated by the reciprocating motion of the membrane frame and the shear force formed on the water flow can effectively strip the pollutants such as sludge and impurities attached to the surface of the MBR membrane wire, prevent the MBR membrane from being blocked due to the accumulation of pollutants, thereby ensuring the stability of the filtering performance of the MBR membrane and improving the purification effect of the sewage.

[0010] Optionally, the opposite sides of the membrane frame are both provided with guide blocks in sliding cooperation with the guide rails.

[0011] By adopting the above technical scheme, the sliding cooperation of the guide blocks and the guide rails provides accurate guidance and stable support for the motion of the membrane frame, and effectively limits the motion track of the membrane frame, avoids the occurrence of the moving deviation of the membrane frame due to water flow impact and other factors, thereby ensuring that the MBR membrane is always in a good working position and angle during the filtering process, maintaining the full utilization of the filtering area and the uniform consistency of the filtering effect.

[0012] Optionally, the purified water tank is equipped with a backwash water tank and a chemical dosing tank. The outer surface of the chemical dosing tank is provided with a chemical dosing pipe that communicates with the inside of the backwash water tank. A chemical dosing valve is provided on the chemical dosing pipe. A flushing port is opened at the end of the RO purified water pipe away from the water pump. The flushing port is connected to the backwash water tank through a flushing pipe. A flushing pump and a flushing valve are provided on the flushing pipe.

[0013] By adopting the above technical solution, when backwashing of the RO water purification pipe is required, the dosing valve is opened, and the chemical agent enters the backwash water tank through the dosing pipe and combines with the water. Then, the flushing pump is started and the flushing valve is opened. Under pressure, the flushing water enters the RO water purification pipe from the flushing port through the flushing pipe. When the flushing water comes into contact with the inner wall of the RO water purification pipe, the scouring force of the water flow and the chemical action of the chemical agent remove impurities, dirt, microorganisms and other pollutants accumulated on the inner wall of the RO water purification pipe. This effectively prevents the RO water purification pipe from deteriorating due to blockage and scaling, and ensures the purification effect of the RO water purification pipe on the water body.

[0014] Optionally, multiple RO water purification pipes are connected by a return pipe, the end of the return pipe away from the RO water purification component is connected to the backwash water tank, and the return pipe is equipped with a return valve and a return pump.

[0015] By adopting the above technical solution, some of the water treated by the RO water purification pipe flows back to the backwash water tank through the return pipe, thereby effectively replenishing the backwash water tank and ensuring a continuous and sufficient supply of backwash water, thus ensuring that the backwash operation can be carried out in a timely and smooth manner when needed.

[0016] Optionally, the backwash water tank is equipped with a stirring assembly, which includes a main stirring rod and multiple auxiliary stirring rods rotatably connected inside the backwash water tank.

Both the main stirring rod and the multiple auxiliary stirring rods are equipped with multiple stirring blades. The backwash water tank is equipped with a rotating assembly that drives the main stirring rod and the auxiliary stirring rods to rotate synchronously.

[0017] By adopting the above technical solution, after the agent is added to the backwash water tank, the drive assembly drives the main stirring rod and multiple auxiliary stirring rods to rotate synchronously. During rotation, the stirring blades agitate the agent and rinsing water inside the backwash water tank in all directions, ensuring that the agent is evenly dispersed in the backwash water. This allows the chemical agent to fully contact and react with the contaminants in the RO water pipes during backwashing, greatly improving the cleaning effect. At the same time, uniform agitation also avoids adverse effects such as corrosion of the backwash water tank and RO water pipes due to excessively high local agent concentrations, or incomplete cleaning due to excessively low local agent concentrations.

[0018] Optionally, the rotating assembly comprises a first motor arranged on the backwashing water tank, an output shaft of the first motor is fixedly connected with the main stirring rod, a driving gear is fixedly sleeved on the main stirring rod, a plurality of driven gears corresponding to the auxiliary stirring rods are arranged in meshing mode on the driving gear, the driven gears are fixedly connected with the auxiliary stirring rods, and a gear ring is arranged on an inner circumferential side wall of the backwashing water tank and is in meshing mode with the driven gears.

[0019] By adopting the above technical scheme, when stirring, the first motor is started, the first motor drives the main stirring rod to rotate, the main stirring rod drives the driving gear to rotate, and the driving gear drives the plurality of meshing driven gears to rotate, so that the synchronous rotation of the plurality of auxiliary stirring rods is realized. Meanwhile, under the arrangement of the gear ring, the driven gears will move circumferentially along the gear ring in the process of rotation, the movement of the driven gears drives the plurality of auxiliary stirring rods to move along the inner circumferential side wall of the backwashing water tank, so that the stirring range of the stirring assembly is further expanded, the mixing effect of the medicament and the backwashing water is further improved, and the uniformity of the medicament in the backwashing water is improved.

[0020] Optionally, a polytetrafluoroethylene coating is coated on the inner side wall of the backwashing water tank.

[0021] By adopting the above technical scheme, the polytetrafluoroethylene coating has good chemical stability, can effectively resist the erosion of various chemical agents and impurities, prevent the inner side wall of the backwashing water tank from being corroded, swelled or other chemical damage, and significantly prolong the service life of the backwashing water tank.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. By arranging the water pump and the RO water purification assembly, when purifying, the water purified by the MBR is sucked into the RO water purification pipe by the water pump, the RO water purification pipe performs deep purification on the water treated by the MBR membrane by means of the reverse osmosis principle, accurately traps small-molecule organic matter and microorganisms and other pollutants that are difficult to be removed by the MBR membrane, successfully prevents these impurities from entering the final water body, and greatly improves the removal rate of various pollutants in sewage by combining the MBR and RO purification processes, thereby significantly improving the overall sewage purification effect.

[0024] 2. By arranging the driving assembly and the guide rail, the membrane frame reciprocates along the guide rail under the driving of the driving assembly, the inertia force generated by the reciprocation of the membrane frame and the shear force formed on the water flow can effectively strip the sludge, impurities and other pollutants attached to the surface of the MBR membrane, prevent the MBR membrane from being blocked due to the accumulation of pollutants, and thereby ensure the stability of the filtration performance of the MBR membrane.
