Embodiment Construction

[0011] exist figure 1 In the center, there is a water tank, which adopts the method of water inflow from the bottom and water out from the top. An aluminum-based photocatalyst filter is arranged every 20cm in the direction of water flow in the vertical direction, and nano-TiO is attached to it. 2 , between every two aluminum-based photocatalyst filter screens, a sealed ozone-producing ultraviolet lamp is arranged every 20cm according to the width. The lamp tube is sealed with a lampshade, and the ultraviolet lamp is arranged vertically. Above the water body, the lamp head will be fixed on the sealed top cover of the box. Between every two layers of filter screens, ceramsite nanosphere purification materials are also arranged, and air pipes are arranged at the bottom of the box for blower aeration. Sewage enters the box through the water inlet, and the ozone-producing ultraviolet lamp exerts a huge oxidation ability when it generates ozone. Combined with the ceramsite nanosphe...

Abstract

The invention discloses a novel combined device for treating ammonia nitrogen in wastewater. The combined device comprises a water inlet, a water outlet, a water tank, a photocatalyst filtering screen, an ultraviolet lighting tube, a sealing cover plate, an aerating device and a ceramsite nanosphere purifying material. When the combined device is energized, the ultraviolet lighting tube emits light to generate ozone, the ozone is combined with wastewater, a photocatalyst fulfills a strong catalytic degradation function under the actions of ultraviolet light and ozone, the aerating device aerates at the bottom of a tank, and the ceramsite nanosphere purifying material is stirred and mixed with ozone and wastewater to play a good role of catalyzing. Therefore, ammonia nitrogen and organic matters in the wastewater can be degraded effectively, microorganisms such as bacteria and fungi can be removed from the wastewater, and the wastewater can be purified to reach the national relevant wastewater discharge standard. The novel combined device disclosed by the invention is low in cost, is convenient to install and use and can be assembled into large and medium-sized water treatment equipment and household small-sized water treatment equipment.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to the treatment of wastewater with high ammonia nitrogen content. Background technique [0002] At present, there are mainly physical and chemical methods, biological methods and biochemical combined methods for the removal of high-concentration ammonia nitrogen in industrial wastewater. However, whether it is a physical-chemical method, a biochemical method or a combined biochemical method, it is inseparable from a pretreatment process with high investment and high operating costs. The cost of the operation process is high, and the treatment effect is poor, and it is difficult to meet the existing national emission standards. Require. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a new wastewater ammonia nitrogen treatment device, which can not only achieve better...
