Novel sewage treatment device

Patent No.: ZL201420242432.9

Application date: 2014.05.13

Announcement (announcement) date: 2014.09.17

Main technical features:

ü The treatment device includes a glass greenhouse, a support grid, an aeration head and a packing layer, and is a buried type

ü There is a support grid in the middle of the glass greenhouse to separate the glass greenhouse from the upper space area and the lower space area. The front end of the lower space area is provided with a water inlet, the rear end of the lower space area is provided with a water outlet, and the front end of the lower space area is provided with an air inlet. A row of aeration heads is arranged at the bottom of the lower space zone, and a filler layer is arranged on the aeration head

ü The packing layer is a two-stage parallel floc elastic packing block fixed by ropes. The structure of the elastic packing is to change the original plastic sheet into double-loop large plastic ring, and press the hydroformylated fiber or polyester yarn on the ring. On the circle, the fiber bundles are evenly distributed, and the inner ring is a snow-like plastic branch, which can not only hang the film, but also effectively cut the bubbles, improve the oxygen transfer rate and utilization rate, and make the water-gas biofilm fully exchanged to make the organic matter in the water. Efficiently processed

ü Introduced ecological engineering technology to support the large number of emergent plants on the mesh of the grid to provide a healthy habitat for the growth of bacteria and other organisms in the sewage, using aeration and packing layers to ensure microbes Reproduction and metabolism, using inoculated and domesticated microorganisms to decompose organic matter in sewage, converting it into stable inorganic matter, increasing sludge concentration, reducing excess sludge volume, high efficiency of COD and ammonia nitrogen removal, and improving the smell of sewage

ü The processing device has a high degree of automation, which can basically achieve unattended operation, continuous water inflow, continuous water discharge, and flexible processing methods.

ü The treatment unit has a high load resistance and does not need to consider the sludge expansion problem.

ü The effluent water quality is stable and can reach the national first-class A standard. The effluent can be reused for greening or flushing water after further disinfection.

ü The treatment device has beautiful appearance, short processing time, small floor space, low power consumption, energy saving and running cost, can be applied to industrial wastewater of domestic sewage or domestic sewage, and can also be placed in anaerobic treatment system of industrial wastewater. Department, especially suitable for building in high-end communities
