preparation example Construction

[0033] see figure 1 According to the first embodiment provided by the present invention, the method for preparing the above-mentioned catalytic oxidant suitable for rapid sewage treatment, the preparation method includes the following steps:

[0034] S1, screening bamboo charcoal particles; preferably, the particle size of the bamboo charcoal particles screened is 0.8mm-1.5mm, which can prevent the bamboo charcoal particle size from being too large to block the equipment during use, and if it is too small, the oxidation effect is poor;

[0035] S2, soaking for the first time, soaking the screened bamboo charcoal particles in an alkali solution for 6 hours; specifically, the concentration of the alkali solution is 2.5%;

[0036] S3, rinse for the first time, take out the bamboo charcoal particles soaked for the first time, filter and dry, rinse with tap water until neutral;

[0037] S4, drying for the first time, putting the bamboo charcoal particles after the first washing in...

Abstract

The invention provides a catalytic oxidant suitable for fast sewage treatment. The catalytic oxidant is mainly prepared by soaking bamboo charcoal particles in a blend system of iron, titanium, copper, lanthanum, palladium and an ethanol solution. The invention further provides a preparation method of the catalytic oxidant suitable for fast sewage treatment. The catalytic oxidant suitable for fastsewage treatment is loaded with a multi-metal blend with very high activity, by controlling sintering through temperatures, the metal blend is attached to the bamboo charcoal particles firmly, underinduction of an oxygen source, an oxidant is in contact with a water body to trigger high energy potential, the chemical oxygen requirement and ammonia nitrogen in the water body are subjected to direct oxygenolysis treatment to generate gas and water, and the purpose of cleaning the water body can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of sewage treatment, in particular to a catalytic oxidant suitable for rapid sewage treatment and a preparation method thereof. 【Background technique】 [0002] At present, the mainstream technology used in sewage treatment at home and abroad is biological method (including activated sludge). Biology mainly cultivates domesticated microbial flora to decompose organic pollutants in sewage. Certain nutrients and saturated dissolved oxygen required for microbial growth can accelerate the metabolism of biological flora. Microbial cultivation, domestication, and growth are complex processes. Carbon and nitrogen are one of the key factors, which directly affect whether the quality of effluent after treatment is stable and meets discharge standards. . At present, some sewage treatment uses catalytic oxidants for oxidation, but the cost of catalytic oxidants is too high to be widely used. 【Content of invention】 ...
