Abstract:
By means of seeding EM(effective microorganisms)to domestic wastes, the concent ration of total phosphorus can be decreased sharply .The experiments show that aeration and the alkaline environment are needed.When the total phosphorus of domestic wastes is 4.295-29 .839mg/L, the optimum reaction conditions are as follows:the dosage is 0.8%, pH is 8, the aeration time is 6hours and the reaction time is 24 hours.Key words:effective microorganisms;domestic sew age;total phosphorus
Key words:
effective microo rganisms,
domestic sew age,
total phosphorus
摘要：
向生活污水中接种有效微生物群(EM), 能显著地降低其中总磷(TP)的浓度。试验证明, 曝气和碱性环境是必不可少的两个条件。对于原水总磷在4.295- 29.839mg/L之间变化的污水, 得出去除总磷的建议最佳组合:接种量08%、pH值为8、曝气时间为6h、反应时间为24h。
