Problems solved by technology

The disadvantage is that the conditions for microbial cultivation are strict, and the water temperature generally needs to be above 15°C to achieve the expected treatment effect.
However, the water temperature in winter and spring is only 0°C to 4°C, which cannot meet the temperature requirements at all, and the initial equipment investment and daily operation costs are expensive
[0003] The activated carbon adsorption method adopts activated carbon adsorption treatment, which has the advantage that it is not limited by temperature and environmental conditions, the treatment process is simple to operate, and the adsorption efficiency is high; the disadvantage is that the activated carbon adsorption method is only suitable for treating low-concentration wastewater, and the activated carbon after use needs to be treated again. Activation before reuse

Embodiment 1

[0027] According to the adsorption material for potato starch wastewater treatment of the present invention, the adsorption material comprises clinoptilolite, bentonite, activated carbon, and the sensory requirements of clinoptilolite and bentonite are white, without moldy deterioration, caking, peculiar smell, and abnormal smell, Activated carbon contains small amounts of black carbon particles. The moisture content is less than or equal to 10%; the crushed particle size is less than 2.5mm, the particle size greater than 1.25mm is less than or equal to 10%, and the coefficient of variation of mixing uniformity is less than or equal to 5%.

[0028] The raw material ratio is as follows:

[0029] (1) According to the weight ratio, it includes 40% clinoptilolite, 40% bentonite, and 20% activated carbon. The particle size distribution of clinoptilolite is 60-80 mesh, accounting for 80%, and 100-200 mesh, accounting for 20%. The particle size distribution of bentonite is 80-100 me...

Abstract

The invention relates to the field of waste water disposal, and particularly relates to an absorbing material for waste water treatment of potato starch and its application. The absorbing material isprepared from 40-60% of clinoptilolite, 30-40% of bentonite, and 10-20% of active carbon. By adopting a series of modifying methods, the absorbing efficiency is greatly improved, the mixture ratio ofvarious absorbing materials is adjusted and optimized, and the absorbing effect of collaboration and mutual synergism is reached. Natural mineral matters after absorption can be directly used as the animal feed and soil conditioner after being dried and smashed.

Description

technical field [0001] The purpose of the invention relates to the field of wastewater treatment, in particular to an adsorption material and application for potato starch wastewater treatment. Background technique [0002] At present, the treatment of potato starch wastewater mainly adopts biological treatment method, activated carbon adsorption method and natural mineral component adsorption method. Biological treatment mainly uses the metabolism of microorganisms such as bacteria, molds or protozoa to convert organic pollutants in wastewater into their own cellular substances and simple compounds, making them stable and harmless, thereby purifying the water quality. Its advantages are that it is suitable for the treatment of high-concentration organic wastewater, and the cost of large-scale treatment is low and the treatment efficiency is high. The disadvantage is that the conditions for microbial cultivation are strict, and the water temperature generally needs to be ab...
