摘要
我国食用菌生产量巨大,但菌渣的利用率低,废弃菌渣造成了很严重的环境污染。本文分析了废弃菌糠袋的成分及对周边土壤和水体水质的影响。在实验室对菌糠破碎、加温、超声处理后,确定了菌糠溶于水后呈弱碱性,会溶出大量难降解有机物,使水体色度增加。其他化学性指标如硝酸盐、总磷、总氮、重金属元素铁、锰等均有大量溶出,并提出了菌糠的污染防治措施。
The production of edible fungi is huge in our country, but the utilization rate of mushroom dregs is lower, waste mushroom dregs cause serious environmental pollution. This article analyzes the composition of waste mushroom bran bags and its effect on surrounding soil and water quality. After breaking, heating and ultrasonic treatment of mushroom bran in laboratory, it was determined that the water solution of mushroom bran is weakly alkaline, and would precipitated a large number of refractory organics, made the colourity of the water increase. Accounting the total pollutants, the precipitation of mushroom bran, such as nitrate, total phosphorus (TP), total nitrogen (TN), heavy metal elements such as iron, manganese element have a large number of solubilise , and the paper is proposed the pollution control measures of mushroom bran.
