Abstract :
Study on the dewatering and drying effect of Scirpus Tabernaemontani, Tall Fescue, Yellow Iris and Reed in the ecological bed, and determinate sludge dosage in the ecological bed. The results show that: the gravity dewatering time of Yellow Iris beds and Reed beds are only 6 hours. And when the sludge dosage is 200L/m2, dosing period is one time per 4 days, ammonia nitrogen and total nitrogen removal rate of sludge are up to 86.7% and 50.0%.
