Suspension membrane plate for sewage treatment, preparation method and application thereof

Abstract

The invention discloses a suspended membrane plate for sewage treatment, a preparation method and its application. The preparation method of the suspended template includes the following steps: S1, prepare iron-nitrogen co-doped TiO 2 Powder; where, molar ratio, TiO 2 : Fe: N=1: (0.00108~0.00132): (0.252~0.308); S2, prepare an aqueous solution of trimethylol ethane, and prepare TiO co-doped with trimethylol ethane and the iron nitrogen. 2 The mass ratio of the powder is 0.005 to 0.008:1 and mixed, and the ultrasonic machine is used to oscillate and mix evenly to obtain titanium dioxide slurry; S3, prepare an aqueous solution of the silane coupling agent, and immerse the suspendable plate into the aqueous solution of the silane coupling agent for 60 to After 120 minutes, take it out and drain it; S4, immerse the suspendable plate into the titanium dioxide slurry, soak it for 10 to 20 minutes, then take it out and dry it; S5, repeat step S4 until the thickness of the film on the surface of the plate reaches the set thickness. The suspended membrane plate prepared by the invention can effectively degrade pollutants and is easy to use.

Description

【Technical field】 [0001] The invention relates to a sewage treatment method, in particular to a suspended membrane plate for sewage treatment, a preparation method and application thereof. 【Background technique】 [0002] As an important natural resource, water resources are an indispensable and irreplaceable material for economic development, social stability and people's life, and an important guarantee for sustainable economic and social development and stability. The pollution of the water environment and the shortage of water resources are two major problems facing the social development of our country at present. The construction of urban sewage plants has reduced the pollution of sewage to the environment. The shortage of water resources needs to be solved by the development of new water sources and the reuse of water resources. As a stable and reliable water resource, urban sewage has become a strategic countermeasure for many countries in the world to solve the wat...

Problems solved by technology

But although there are certain effects, these treatment processes are not very satisfactory in general. On the one hand, the cost is high, and on the other hand, it is easy to cause secondary pollution.

More importantly, these denitrification methods only transfer pollutants from one medium to another, but do not fundamentally degrade pollutants, and cannot effectively make pollutants completely harmless
