Problems solved by technology

However, this device also has certain limitations. It is designed for the aerobic activated sludge method and focuses on the integration of aeration tanks. However, in a pure aerobic activated sludge device, the purpose of phosphorus removal cannot be achieved, and the application range is not enough. widely

Embodiment Construction

[0020] The technical solutions of the present invention will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings.

[0021] like figure 1 As shown, an integrated domestic sewage nitrogen and phosphorus removal device includes a cylindrical tank body 1 and a mud-water separation device.

[0022] like figure 2 , 3 , 4, the pool body 1 has a cover plate, and the side wall of the pool body 1 is provided with a water inlet pipe 8 and an outlet pipe 11. The bottom surface of the said pool body 1 is provided with a perforated aeration tube 9, the side length of the perforated aeration tube 9 is between the diameter of the mud-water separator and the diameter of the pool body 1, and the upper semicircle of the cross section of the perforated aeration tube 9 is Two rows of aeration holes 10 with a diameter of 3-5 mm are arranged at an angle of 90°.

[0023]A metal bracket is used to fix the mud-water separator above...

Abstract

The invention discloses an integrated life sewage nitrogen and phosphorus removal apparatus, which can be widely used for nitrogen and phosphorus removal treatment of the life sewage, and comprises a cylindrical pool body and a mud-water separation device. A water inlet and a water outlet are provided on the sidewall of the pool body. A through-hole aerated tube is arranged on the bottom of the pool body. The mud-water separation device is fixed in the pool body by a metal support, and is divided into to two grades, and a physical phosphorus removal area and an electrochemistry nitrogen removal area are arranged in a two grades mud-water seperator. A cover plate is provided with the pool body, an air exhaust opening is provided on the cover plate, and an electrical cabinet is provided, an air pump, a time switch and a current stabilization transformer are arranged in the electrical cabinet, and the electrical cabinet is connected to a solar energy power device. By aiming the characteristics of life sewage, the apparatus has the advantages of compact structure and simple management, the integrated design is capable of substantially reducing the land occupation, no sludge backflow system is provided, the cost of investment and operation is low, thereby the integrated life sewage nitrogen and phosphorus removal apparatus is a bioelectrochemical sewage treatment device with the characteristics of no power consumption and economical and practical effects.

Description

technical field [0001] The invention relates to a method for denitrification and dephosphorization of domestic sewage combined with biology, electrochemistry and physics, in particular to an integrated non-power consumption distributed denitrification treatment device for domestic sewage. Background technique [0002] my country's long-term urban-rural dual structure has led to significant differences between urban and rural areas in terms of sewage treatment: in cities, there are not only complete sewage collection pipe networks for centralized and effective treatment of sewage, but also the state promulgates and builds a system of laws, regulations and standards to control 96% of the villages in the vast rural areas, which account for nearly 90% of the country's total area, do not have drainage channels and sewage treatment systems. A large amount of untreated domestic sewage is discharged through point sources and non-point sources, bringing various pollutants into rivers,...
