Measuring Nitrogen and Phosphorus Contents of Sludge Composted with Different Treatments

摘要：

The total nitrogen and phosphorus contents were determined by using the methods of semi-micro Kjeldahl and the sodium hydroxide fusion under different treatments of sludge composting. The results were as follows: (1) The nitrogen and phosphorus contents of the sludge single treatment increased slightly, nitrogen was only more 0.20％, phosphorus higher 0.19％ at the end of composting, compared with the beginning of composting. (2) Adding fermentation accelerant in the sludge from 8％ to 40％, the nitrogen and phosphorus contents increased from 1.05％ to 5.02％ and from 0.19％ to 2.81％ at the end of composting, compared with the beginning of composting, but were lower 36.99％ to 6.60％ and 4.29％ to 0.98％ respectively, compared with the sludge single treatment. (3) As increasing the amount of nutrient agent from 30 to 50％, the nitrogen and phosphorus contents were more 0.20％ to 1.22％ and 0.19％ to 2.18％ at the end of composting, compared with the beginning of composting. (4) Under 24％ of the fermentation accelerant agent to the sludge, as the increased nutrient agent treatments from 8％ to 32％, the nitrogen and phosphorus measured were more 0.20％ to 1.42％ and 0.19％ to 2.35％ at the end of composting, compared with the beginning of composting, but were lower 22.94％ to 20.81％and 10.98％ to 1.37％ respectively, compared with the sludge single compost.
