2results about How to "Reduce water load" patented technology

This utility model discloses a high-efficiency denitrification wastewater treatment device based on A2O. The internal space of the tank is divided into an equipment room, an influent tank, an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a filtration tank by a partition. The sedimentation tank is equipped with a sludge return device and is connected to the anaerobic tank through the sludge return device. A plug flow zone is located in the middle of the anoxic tank, and an air-lift plug flow device is installed in the plug flow zone, dividing the anoxic tank into a first anoxic section and a second anoxic section. A drainage hole is provided on the partition between the aerobic tank and the sedimentation tank. A return hole is opened on the partition near the anoxic tank at the output end of the aerobic tank, and the output end of the aerobic tank is connected to the first anoxic section through the return hole. The area of ​​the return hole is larger than the area of ​​the drainage hole. This utility model can reduce the impact of wastewater influent load, improve wastewater treatment capacity, and reduce energy consumption.

The application provides a glass grinding and cleaning wastewater recycling device, which comprises a cleaning frame and a recycling pool, a plurality of drainage pipes are fixedly connected to the side of the cleaning frame, the recycling pool is on the ground on one side of the cleaning frame, and a plurality of coarse filter assemblies and a plurality of standby filter assemblies are further included. The coarse filter assemblies and the standby filter assemblies below the coarse filter assemblies are connected in parallel, when a coarse filter assembly is blocked and needs to be cleaned, the standby filter assembly below the coarse filter assembly can be automatically or manually switched to a working state to temporarily filter the wastewater, so that the blocked coarse filter assembly can be cleaned offline without affecting the normal work of other filter units, the continuity of the entire wastewater recycling process is ensured, and the utilization rate and the processing efficiency of the device are significantly improved.
