Problems solved by technology

In fact, the device has a strong ability to deal with biological organic matter pollution, especially the removal of nitrogen and phosphorus, but its ability to treat industrial wastewater containing refractory organic matter is weak, that is, the device can reduce the biological oxygen demand (BOD) of polluted water bodies. ), but it is difficult to reduce the chemical oxygen demand (COD)

Embodiment Construction

[0012] The equipment prepared by the invention is mainly used for treating organic sewage in polluted rivers and lakes, and the subsequent treatment process of industrial organic wastewater. During the processing, strong sunlight is required, which is beneficial for the equipment to exert its photolysis function. Provide following embodiment in conjunction with content of the present invention:

[0013] First, 10 kg of anatase-type TiO2 nanoparticle slurry was prepared by conventional sol-gel method, and then Ag / TiO2 was prepared by photochemical deposition 2 catalyst of light. Nine pieces of glass fiber cloth 1 with a length of 3 meters and a width of 0.5 meters were immersed in the modified titanium dioxide nanoparticles Ag / TiO 2 Take it out after 3 hours in the slurry, and bake it in a muffle furnace at a temperature of about 400° C. for 3 hours. Be that the plastic pipe 2 lap of 80mm grows 3 meters, wide 2 meters, the cuboid frame of height 0.5 meter with outer diameter...

Abstract

A process for preparing the sewage treating apparatus includes such steps as preparing the slurry of anatase-type TiO2 nano-particle by sol-gel method, preparing photocatalyst Ag / TiO2 by photochemical deposition method, adding TiO2 to AgNO3 solution, adsorbing while stirring, radiating by low-pressure Hg lamp, distilled water washing to remove excessive Ag ions, braiding glass fibers to obtain needed shape, immersing it in modified TiO2 nano-particles slurry, sintering and installing it to the frame made of plastic tube.

Description

technical field [0001] The invention relates to a manufacturing method in the field of environmental protection technology, in particular to a manufacturing method of polluted water treatment equipment. Background technique [0002] my country is a country that lacks water resources, and the per capita water resources only account for 25% of the world's per capita water resources. With my country's rapid economic development, rapid population growth, and the acceleration of urbanization, the intensity of water resource utilization has increased rapidly, organic pollution in rivers and lakes is widespread, water eutrophication, and non-point source pollution have become increasingly prominent. Accelerated tendency to worsen. The eutrophication of the water body destroys the landscape water body, emits stench, and makes the water body lose its due functions such as self-purification and exchange. Among them, the treatment of refractory organic industrial wastewater is a diffi...
