Abstract

The invention discloses a platanus branch treatment method which comprises the following steps: airing, crushing and screening pruned platanus branches; calcining the branches in a tube furnace so asto obtain platanus branch charcoal; immersing the platanus branch charcoal into a hydrogen peroxide solution having a mass fraction of 1-5% for soaking for 1-5 hours, filtering and washing, immersinginto hydrochloric acid with a concentration of 1 mol / L for soaking for 2-5 hours, immersing into an aluminum sulfate solution having a mass fraction of 5-40%, filtering and drying; performing anaerobic decomposition under the condition of 500-800 DEG C for 30-60 minutes; drying and screening to obtain modified platanus branch charcoal; dewatering, drying, grinding and screening the residual sludgein a sewage treatment plant, and mixing with the modified platanus branch charcoal according to a volume ratio of 1 to 3-5, so as to obtain the adsorbent. By taking the adsorbent as an adsorbing material of polluted water, the pollution problems of lakes, rivers and other water bodies can be solved.

Description

technical field [0001] The invention relates to the technical field of solid waste disposal and treatment, in particular to a method for treating sycamore branches. Background technique [0002] The shape of the plane tree is majestic and dignified, the leaves are large and shaded, the dry skin is smooth, and the adaptability is strong. It is widely cultivated in various places, and it is also resistant to pruning and shaping. It is widely used in urban greening. spectacular. And because of its strong resistance to a variety of toxic gases and the ability to absorb harmful gases, it can cool down in summer, retain dust, reduce noise, absorb harmful gases, increase the relative humidity of the air, adjust the balance of carbon dioxide and oxygen, and improve air quality. Obviously, it is quite suitable as a greening for neighbors, factories and mines. [0003] If the French plane tree is not trimmed and trimmed in time during the growth process, the tree shape will be messy...
