摘 要: 对潮州市第一污水处理厂的污泥泥质进行了分析研究。结果表明,脱水污泥通常接近中性(pH=6.43~7.14),污泥中富含有植物生长所必需的营养元素和多种微量元素,如P(0.25%~0.49%),N(4.05%~6.12%),Mg(6352.4mg/kg~8255.9mg/kg),K(1240.7mg/kg~1512.9mg/kg),Ca(2891.3mg/kg~4199.6mg/kg),Mn(5474.3mg/kg~6939.2mg/kg),Fe(8.079%~8.828%)等。因此,污泥供肥潜力较大,是一种值得合理利用的肥源。 Aceording to the analysis on the sludge in Chaozhou' s first sewage treatment plant, the result indicates the dehydrated sludge usually approaches the neutrality (pH= 6.43-7.14)and it has many nourish elements and miro-elements needed by plants, for example P (0.25 %-0.49 %), N (4.05 % -6.12 %), Mg (6352.4 mg/kg-8255.9 mg/kg), K(1240.7 mg/kg- 1512.9 mg/kg), Ca (2891.3 mg/kg-4199.6 mg/kg), Mn (5474.3 rng/kg-6939.2 mg/kg), Fe(8.079 % -8.828 % ),etc. Therefore, the sludge has great potential as a good fertilizer which is worthy of the reasonable reuse.
