项目摘要

On the water purification of river, lakes and marshes, in coming to rate for achievement environmental quality standard (BOD) of lakes and marshes, while the necessity is understood, 81% the preceding year similar, rate for achievement environmental quality standard (COD) of the river do not pass at the slight 40.9%, and it almost levelly stagnates for past of 25 years, and the urgent purification countermeasure is desired.Removed sludgy processing technology has not been established. We developed seedling pot. And, in the cultivation experiment using the sludge of Enokuchi river and Ishitegawa River, there was no abnormality for growth and growth of the plant, and rather it tended to promote the growth. Many organics and inorganic components were included in the sludge. The noxious soil microorganism was few in the sludge. The plant growth was promoted. However, there is the fear which causes the growth of the plant the adverse effect on the saline which is included for the sludge. The regard prosperity there is no the dewatered sludge on the smell, as they can not imagine from the name, either, and there are rich in the usual corrosion. Sludge could be useful for dilution of nutrient in the range of optimum crop grown in the salt accumulation soil as continuous green house soil too.

在河流、湖泊和沼泽的水质净化方面，在了解到湖泊和沼泽的环境质量达标率（BOD）的必要性的同时，与上年81%相似，河流的环境质量达标率（COD）仅为40.9%，近25年来几乎处于水平停滞状态。污泥处理技术尚未建立。我们研制了钵苗。而且，在使用江之口川和石手川的污泥的栽培实验中，植物的生长和生长没有异常，而是倾向于促进生长。污泥中含有多种有机物和无机物。污泥中有毒土壤微生物较少。促进了植物的生长。然而，人们担心这会导致植物的生长对污泥中含有的盐水产生不利影响。至于繁荣没有脱水污泥上的气味，因为他们无法想象从名称，要么，并有丰富的通常腐蚀。污泥还可作为连续绿色房屋土壤，在适宜作物生长的范围内稀释养分。
