Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that traditional fillers have weak function of intercepting oxygen and low reoxygenation efficiency in non-powered or micro-powered devices, and provide a kind of application of hydrophobic materials. The present invention can increase the contact area between water surface and air and Contact time, thereby improving the reoxygenation performance of biofillers

Embodiment 1

[0029] An application of a hydrophobic material, the hydrophobic material is applied to a biological filler, and the reoxygenation function of the biological filler is improved.

[0030] In the present invention, the hydrophobic material refers to a hydrophobic material with a wetting angle greater than 90° and a porosity preferably greater than 10%.

[0031] The invention mainly utilizes that the hydrophobic material has weak affinity with water and is repellent to water, thereby forming a gas film in the water, increasing the gas-liquid contact time and contact area, thereby increasing the dissolved oxygen in the water. The invention uses hydrophobic materials to replace traditional polyethylene / polypropylene and other materials as a biological filler bracket or shell to form a combined filler, which is applied to a dispersed non-powered or micro-powered sewage treatment device. When this combined filler is added to water, the porous hydrophobic material will bring air into ...

Embodiment 2

[0038] The hydrophobic material is made into a supporting structure, a partition or an airflow uniform structure of the biological filler, and is applied in the facultative or aerobic area of ​​the sewage purification system.

[0039] Further, the supporting structure may be a scaffold or a shell, and the scaffold or shell of the biological filler is made of hydrophobic material.

Embodiment 3

[0041] When the biological filler is a suspended biological filler, the shell of the suspended biological filler is made of hydrophobic material, used in combination with the suspended biological filler, and added to the facultative or aerobic zone of the sewage purification system.

Abstract

The invention discloses the application of a hydrophobic material. The hydrophobic material is applied to a biological filler and manufactured into a supporting structure, a baffle or an airflow uniform structure which are applicable to a facultative anaerobic region or an aerobic region of a sewage purification system. The application of the hydrophobic material can improve the contact area and the contact time of a water surface and the air, thereby improving the reoxygenation performance of the biological filler.

Description

technical field [0001] The invention relates to the application of a hydrophobic material, which is mainly applied to facultative and aerobic parts in non-powered or micro-powered domestic sewage treatment devices. Background technique [0002] Since the 1980s, domestic sewage purification biogas digesters have gradually developed on the basis of borrowing rural biogas digesters and traditional septic tank technologies. This simple domestic sewage treatment technology has gradually developed into the main technology for the decentralized treatment of domestic sewage in southern my country due to its advantages of decentralized investment, no energy consumption, low operating costs, and land conservation, and has been widely used. [0003] In order to meet environmental protection requirements, this type of domestic sewage treatment and purification device usually needs to realize the function of biological nitrogen and phosphorus removal, and biological nitrogen and phosphor...
