| Research Abstract |
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.
