制糖生产中排出的废物—滤泥含钙为34％,有机质19.35％,全氮0.51％,全磷1.6％,水解氮3.2毫克;速效磷64.5毫克/100克滤泥,速效钾25毫克/100克滤泥,pH值8.0。一个日处理1000吨的甜菜糖厂,大约每天可排出滤泥100吨,年积累量近2万吨。如果对这些滤泥不加以利用,年年积累下去,不仅要大面积占地,对环境也有污染。根据1984年在白浆土上对甜菜施滤泥的试验结果表明,滤泥能提高甜菜产量和含糖,减轻甜菜根腐病的发病家。
Waste generated from sugar production - 34% calcium, 19.35% organic matter, 0.51% organic nitrogen, 1.6% total phosphorus and 3.2 mg hydrolyzed nitrogen, 64.5 mg / 100 g quick-acting phosphorus and 25 mg / 100 grams of mud, pH 8.0. One daily processing of 1000 tons of sugar beet sugar factory, about 100 tons of mud can be discharged per day, the accumulation of nearly 20,000 tons. If you do not make use of these mud filters, accumulated year after year, not only to a large area, the environment is also polluting. According to the test of muddy sugar beet on albacore soil in 1984, it shows that the mud filter can improve the yield of beet and the incidence of sugar beet and reduce beet root rot.
