Abstract

The invention discloses a method for regenerating green energy by utilizing coking wastewater, and belongs to the field of energy conservation and environmental protection. Macromolecular organic matters in the coking wastewater are degraded by means of an electron beam irradiation technology and magnetic magnesium-aluminum hydrotalcite, and the obtained treated coking wastewater dilution is usedfor irrigating plants; and electron beams are used for irradiating plants in the plant growth process, and plants obtained after plant growth is finished are converted into reducing sugar through theenzymolysis saccharification effect. The raw materials used in the method are wastes or cheap and pollution-free compounds, so the method has the characteristics of low cost, and convenience in operation; the organic components in the coking wastewater promote the growth of plants, the growth of the plants can reversely purify the coking wastewater, and the grown plants can be treated to obtain high-added-value products, so the purposes of energy conversion between the coking wastewater and the plants and regeneration of green energy are finally achieved.

Description

technical field [0001] The invention belongs to the field of energy conservation and environmental protection, and relates to a method for regenerating green energy by utilizing coking wastewater. Background technique [0002] Energy crisis and environmental pollution have always been global problems faced by human beings. The development and reuse of waste resources is an effective measure to alleviate energy crisis and environmental pollution. Coking wastewater is the production water and steam condensation wastewater from the initial cooling of coke oven gas and coking production process. It has very complex components, low biodegradability, and is difficult to biodegrade. At the same time, the concentration of various toxic and harmful pollutants is high, which not only seriously pollutes the environment , but also a direct threat to human health. It is imminent to strengthen the research on the treatment and disposal of coking wastewater. [0003] At present, the comm...
