Problems solved by technology

[0003] The purpose of the present invention is to aim at the shortcomings of the prior art, to design a kind of anaerobic / aerobic integrated low energy consumption biofilter sewage denitrification and dephosphorization device, on the basis of the traditional biofilter, absorb it to save energy, and put it into operation The advantage of low cost overcomes the shortcomings of easy clogging and low efficiency of nitrogen and phosphorus removal. The proposed anaerobic / aerobic integrated low-energy biological filter sewage nitrogen and phosphorus removal device has high-efficiency nitrogen and phosphorus removal capabilities and is not easy to use. The advantages of blockage, stable operation, less land occupation, low investment and operation cost, energy saving, simple and convenient management and operation

Embodiment Construction

[0019] Such as figure 1 As shown, the anaerobic / aerobic integrated low-energy biofilter sewage denitrification and phosphorus removal device designed by the present invention includes anaerobic biofilter, aerobic biofilter 8 and water separator 12, and the three are interconnected in turn . The anaerobic biological filter is divided into a sedimentation zone 2 and a filter zone 4, and the filter zone is provided with a filler 5. The aerobic biological filter is provided with filler 9, the upper part of the filler is the distribution channel 6 and the diversion weir 7, and the two communicate with each other in a cross shape, one end of the distribution channel is connected with the anaerobic biological filter, and the lower part of the filler is provided with a vent 10.

[0020] The water separator in the device of the present invention can have two different structural forms, the first is cylindrical, such as image 3 with Figure 4 As shown, the center of the cylinder is...

Abstract

An apparatus for dephosphating and denitrifying sewage is composed of anaerobic biologic filtering pool, aerobic biologic filter pool and water separator. The said anaerobic biologic filter pool is divided into deposition area and filter area containing filler. The said aerobic bioligc filter pool containing filler has the water distributing canal and guide dam on the filter. Its advantages are high denitrifying power and no need of power.

Description

technical field [0001] The invention relates to an anaerobic / aerobic integrated low-energy biological filter sewage nitrogen and phosphorus removal device, which belongs to the technical field of sewage nitrogen and phosphorus removal with biological filters as the main body, and is suitable for scattered areas such as towns and residential quarters small-scale sewage treatment, especially when nitrogen and phosphorus removal is the main goal or where there is a lack of power and funding sources in the application area. Background technique [0002] In recent years, with the development of industry, agriculture and economy, the eutrophication of closed waters caused by the discharge of sewage with high nitrogen and phosphorus content has become increasingly serious. Therefore, high-efficiency nitrogen and phosphorus removal processes need to be developed; in addition, non-point source pollution in rural areas needs to be controlled urgently, and low-input, low-cost, and easy...
