本造纸厂以生产瓦楞纸为主,主要原料为麦秸、石灰和水,生产后的废水经处理的沉降物主要成份为蛋白质、木质素、半纤维素等,pH值稳定在7.2左右。为了变废为宝,我们利用沉降物进行了栽培草菇试验。首先对沉降物设3个处理:①EM微生物群落处理;②新鲜沉降物;③堆沤一段时间的沉降物。将这三种处理的沉降物分别晒干、粉碎,然后分别以10％、30％、60％、90％的比例与棉子皮混合,同时配以10％的麦
The paper mill to produce mainly corrugated paper, the main raw material for wheat straw, lime and water, the production of wastewater treatment sediment main components of protein, lignin, hemicellulose, pH stable at 7.2 or so. In order to turn waste into treasure, we used sediment cultivation mushroom test. First set up three sedimentation treatment: ①EM microbial community treatment; ② fresh sediment; ③ pile of sediment for a period of time. The sediments of these three treatments were respectively dried and crushed, and then mixed with cotton stalks at the proportions of 10%, 30%, 60% and 90%, respectively, and mixed with 10%
