Absorbing material for waste water treatment of potato starch and its application

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 present invention relates to the field of wastewater treatment, in particular to an adsorbent for potato starch wastewater treatment and its application. 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 [0003] The biological treatment method mainly uses the metabolism of bacteria, molds or protozoa and other microorganisms to convert organic pollutants in the wastewater into its own cellular substances and simple compounds, making it stable and harmless, thereby purifying water quality. Its advantage is that it is suitable for treating high-concentration organic wastewater, low-cost and high-efficiency treatment in large batches. The disadvantage is that the microbial cultivation conditions are strict, and the water temperature generally needs to be above 15°C to achieve the expe...

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

[0004] 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.
