Preparation method of novel biological carbon material

Abstract

The invention provides a preparation method of a novel biological carbon material. The preparation method of the novel biological carbon material comprises the following steps of: (A1) feeding straws, civil sludge and feces into a stirrer, and stirring the straws, civil sludge and feces; (A2) drying a stirred mixture; (A3) feeding the dried mixture into a carbonization stove and carbonizing the dried mixture. The preparation method has the advantages of achieving a good purification effect, turning wastes into wealth, and the like.

Description

technical field [0001] The invention relates to the preparation of carbon materials, in particular to a preparation method of novel biological carbon materials. Background technique [0002] The rain garden is a naturally formed or artificially excavated shallow concave green space, which is used to gather and absorb rainwater from the roof or the ground. Through the comprehensive action of plants and sand, the rainwater is purified and gradually infiltrated into the soil, conserving groundwater, or Make it replenish urban water such as landscape water and toilet water. It is an ecologically sustainable rainwater control and rainwater utilization facility. In actual construction, rain gardens often include gravel layers, sand layers, planting soil layers, mulch layers, and aquifers. The function roughly covers the control of water quantity and water quality: the upper part of water quantity is stagnant storage, which is to ensure a certain hydraulic retention time and redu...

AI Technical Summary

Problems solved by technology

The control of water quality is the most difficult to achieve. Due to the large number of rainwater pollutants and complex components, the mechanism of traditional removal methods is equivalent to the mechanism of soil removal of pollutants, but the ability of soil to remove pollutants is limited, especially for some heavy metals or organic pollution. The adsorption capacity of pollutants is low, which will cause the water body containing pollutants to enter the groundwater through the soil filter layer and sand layer, causing groundwater pollution

In addition, because landscape plants need to be planted on the rain garden, the role of plants can absorb pollutants in the water body on the one hand, and can also play a role in landscaping on the other hand. However, in terms of plant maintenance, pesticides and chemical fertilizers need to be sprayed. The runoff will enter the groundwater, which will aggravate the pollution of groundwater

[0003] Therefore, the current traditional rain garden has the following deficiencies: the ability to remove heavy metals and organic pollutants contained in rainwater is limited; the plants in the rain garden can effectively absorb pollutants; in addition, the application of pesticides and fertilizers will bring In addition, rain gardens need to be poured from time to time due to the poor water retention capacity of the soil in sunny days, resulting in waste of water resources
