The utility model discloses an integrated MBBR (Moving Bed Biofilm Reactor) sewage treatment device and relates to the technical field of sewage treatment equipment. The device comprises a mixing cavity, an aeration cavity, a connecting pipe, a filter plate, a bolt and a brushing mechanism. According to the utility model, the brushing mechanism is arranged; a second rotating rod extends into the mixing cavity from the top end of the mixing cavity, the connection sealing performance of the mixing cavity and the second rotating rod is improved, compared with a traditional connection mode, the situation that sewage in the mixing cavity leaks is avoided, meanwhile, a filter plate is connected with the mixing cavity through a plug pin, rapid disassembly and assembly of the filter plate are facilitated, and the use is convenient. Compared with a traditional mode that the filter plate is installed in the connecting pipe, the convenience of dismounting and mounting of the filter plate is improved, the stirring plate and the brushing plate are driven to rotate through the same power source, the stirring plate rotates and stirs sewage in the mixing cavity, the brushing plate rotates and brushes one end of the filter plate, and the sewage circulation of the filter plate is guaranteed.

The application provides a method and device for treating wastewater by combining a suspended filler floating bed and a soil infiltration system, and the method comprises the following steps: S1, breeding wastewater is treated by the suspended filler floating bed after passing through a hydrolysis tank, and effluent is treated in a sedimentation tank, and wastewater of the suspended filler floating bed is returned to the suspended filler floating bed for secondary treatment; S2, wastewater of the sedimentation tank is returned to the hydrolysis tank; and S3, effluent of the sedimentation tank is introduced into a soil underground infiltration system. The system provided by the application is beneficial to further strengthening the effects of denitrification, phosphorus removal and removal of suspended solids, and solves the problems of low dissolved oxygen content of influent and wastewater in the system, which is not conducive to the growth of nitrifying bacteria, and low effective volume utilization rate. In the use process, the filler does not need to be replaced, and mechanical aeration equipment does not need to be added, and the system has the advantages of low investment cost, no need to add chemical agents for treatment, obvious effect, not easy to breed mosquitoes, simple operation and management, and beautification of the environment, and has remarkable ecological and economic benefits for promoting deep purification of breeding wastewater.

The invention relates to the technical field of efficient aerators, and the efficient aerators comprise an air inlet pipe, the outer part of the air inlet pipe is connected with two connecting flange seats, the upper end of one connecting flange seat is connected with a first aeration pipe, an air outlet hole is formed in the position, close to the top, of the outer part of the first aeration pipe, and the inner part of the first aeration pipe is connected with a first guide pipe; a first air distribution pipe is fixedly mounted at the top of the first guide pipe, six connecting columns are annularly and fixedly mounted outside the first air distribution pipe, a first flow guide umbrella-shaped cover is fixedly mounted outside the connecting columns, a connecting pipe is connected to the upper end of the first flow guide umbrella-shaped cover, and a second air distribution pipe is connected to the top of the connecting pipe; according to the efficient aerator disclosed by the invention, small bubbles are generated through collision of air in the flow guide umbrella-shaped cover, so that a gas-water interface is enlarged; through multiple collisions, small bubbles are forced to be generated and broken for multiple times, and a gas-water interface can be quickly updated, so that the oxygen utilization efficiency is high, and the oxygenation capacity is high.

The utility model discloses a pulse type ecological ditch system which comprises a plurality of ditch modules connected end to end and a circulating unit arranged at the end point of a ditch, the ditch module comprises a precipitation unit, a purification unit and a movable unit which are sequentially arranged from upstream to downstream; the device is used for providing a new effective transformation means for treatment of polluted ditches, on one hand, when water in the ditches is in a small flow, the pulse type fluidity of the water can be kept, meanwhile, particulate matter in the water can be settled, part of solid waste in river water can be effectively intercepted, the solid waste in sewage can be intercepted and manually cleaned, and therefore the effect that the water flow is small is achieved. On the other hand, the functions of irrigation, flood drainage, flood discharge and the like of the riverway are not affected when the water in the ditch is in a large flow.

The present application relates to an aeration device for sewage treatment, comprising a plurality of aeration connecting pipes crisscrossing in a sewage pool, wherein the aeration connecting pipes are provided with a plurality of aeration components, wherein a rubber partition component is provided in the middle of the aeration connecting pipes for dividing the aeration connecting pipes into an upper chamber and a lower chamber, wherein one side of the rubber partition component is connected to the aeration connecting pipes, and the other side thereof abuts against the inner side wall of the aeration connecting pipes; an air intake device is connected to one of the ports of the aeration connecting pipes, and a control valve is provided at the connection between the aeration connecting pipes and the air intake device, wherein the control valve can control the airflow blown in by the air intake device to the upper chamber or the lower chamber of the aeration connecting pipes. The present application has the technical effect of increasing the conveying distance of high-pressure gas and facilitating the cleaning of sludge in the aeration connecting pipes.
