AO工艺同步聚合氯化铝辅助除磷应用研究_鄂宏.pdf

1、 鄂宏 崔鑫 在 深 入了解 除磷机 理的 基础 上 通 过实验 室 小 试 和 生产 性 试 验 研究 AO工艺 同 步 PAC 的 除磷 效果 配 制 浓 度对 除 磷 效果 的 影响 投药 量 与 除磷 效 率 的 关系 得 出 了 PAC 投 加 量 估算 公 式 并 进行了 除磷 成 本核 算 结 果 表 明 AO工艺 同 步 PAC 除磷具 有 良 好 的 除磷 效果 和 运 行 稳 定 性 PAC 适宜的配 制 浓 度为 2 4 PAC 除磷 吨 水 成 本 为 0 06 0 15 元 m 3 PAC 化 学 辅助 除磷 AO工艺 估算 公 式 成 本核 算 Abstract O

2、n the basis of deeply understand of dephosphorization s mechanism the estimation formula for the dosage of PAC was obtained and the cost accounting was carried out through the laboratory and production test In this procedure the dephosphorization s effect of PAC process synchronization in AO process

3、 was researched at the same time the effect of preparation concentration on phosphor removal and the relationship between the dosage and dephosphorization s efficiency was also studied The conclusion indicate the PAC process synchronization in AO process has wonderful effectiveness and performs stab

4、ly on phosphor removal the appropriate preparation concentration of PAC is between 2 4 the cost of PAC on dephosphorization is 0 06 0 15 RMB per ton waste water Key words PAC Polymerization aluminum chloride chemical assistant in dephosphorization AO process estimation formula costaccounting X505 A
