/d。采用“粗格栅及提升泵房+细格栅及平流沉砂池+水解综合池+多级多段改良型AO生物反
应池+二沉池+磁混凝高效沉淀池+反硝化深床滤池+活性焦吸附塔+消毒”工艺。通过水解综合池与
多级多段改良型AO生物反应池的协同作用及活性焦吸附塔的高效吸附,可保证对难降解COD的去
除效果;同时,根据深度处理系统所需的COD去除量,可灵活调节活性焦吸附塔的流量和运行塔的
数量,实现污染物去除量的可控化和经济化。针对较高浓度的总磷(TP),通过生化作用、磁混凝沉
淀池的高效絮凝沉降作用,可将出水TP浓度降至0.10 mg/L。工程运行结果表明,该工艺对COD的
去除率为80%~92%,总氮(TN)和氨氮(NH
3
-N)的去除率分别为79%和96%,TP和悬浮物(SS)的去
除率均达97%以上,出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级
A标准及TP≤0.30 mg/L的限值要求。通过采用集约型深度处理工艺,有效减小了占地面积,可为国
内类似工业园区的废水处理提供参考。

Abstract: To meet the stringent wastewater treatment demands of an industrial park in Zhejiang, a
new wastewater treatment plant was constructed within its boundaries, with a phase Ⅰ construction

/d. The core treatment process adopted was “coarse screen and pumping station +
fine screen and horizontal‑flow grit chamber + hydrolysis comprehensive tank + multi‑stage modified AO
biological reactor + secondary sedimentation tank + magnetic coagulation high‑efficiency sedimentation
tank + denitrification deep‑bed filter + activated coke adsorption tower + disinfection”. The synergistic
effect of hydrolysis comprehensive tank and multi‑stage modified AO biological reactor, coupled with the
exceptional adsorption capacity of the activated coke adsorption tower, ensured effective removal of
refractory COD. Notably, the system allowed for flexible adjustment of the adsorption tower’s flow rate
and the number of units in operation based on the required COD removal amount of the advanced
treatment system, achieving both controllable and cost‑effective pollutant removal. For the high influent

total phosphorus (TP), the combined effect of the biological process and the efficient flocculation
sedimentation in the magnetic coagulation sedimentation tank consistently reduced the effluent TP
concentration to 0.10 mg/L. Operation results showed that COD removal efficiency reached 80%-92%,
total nitrogen (TN) and ammonia nitrogen (NH

-N) removal efficiencies were 79% and 96%, respectively,
and TP and suspended solids (SS) removal efficiencies were both above 97%. The final effluent stably met
the first level A limit of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB
18918-2002), as well as the strict TP limit requirement of ≤0.30 mg/L. By adopting an intensive
advanced treatment process, the land area required has been significantly reduced, which can provide a
valuable reference for the wastewater treatment in similar industrial parks in China.

1 工程概况
浙江某工业园区是以锂电、化工为主导产业的
现代化特色工业园,现入驻企业200余家,主要包括
双氧水制造、阻燃材料、五氧化二磷、有机硅复合聚
醚、共聚酯热熔胶及变压器等生产企业。虽然各企
业内部均设有废水预处理设施,但由于企业数量多
且分布分散,排水污染物成分复杂,尤其难降解
COD和总磷(TP)浓度较高,故处理难度较大。
在本工程建设前,园区工业废水和生活污水均
排入当地城镇污水处理厂,但该厂未设置针对化工
废水的专门处理工艺。根据《化工园区开发建设导
则》和《浙江省化工园区评价认定管理办法》,化工
园区须配套建设满足化工废水处置要求的集中式
污水处理设施。因此,为提升园区发展水平,新建1
座污水处理厂成为必然选择。
通过对园区工业污染源及生活污染源的分析,
确定新建工业园区污水处理厂总规模为 2 万 m
3
/d,
分两期实施。一期工程建设规模为1万m
3
/d,其中,
工业污染源污水量占比 90%~95%。项目总占地面
积 2. 90 hm
2
,一期工程用地 1. 75 hm
2
。鉴于一期用
地较为紧张,工艺选择需兼顾占地面积小与处理效
率高的要求。经综合考虑,一期主体污水处理工艺
采用“水解综合池+多级多段改良型 AO 生物反应
池+磁混凝高效沉淀池+反硝化深床滤池+活性焦吸
附塔”。
2 设计水质
综合当前工业企业污水排放的实际情况以及
拟引进企业的相关资料,通过加权平均法综合计算
工业废水和生活污水的水质指标,从而确定污水处
理厂的进水水质。设计出水水质执行《城镇污水处
理厂污染物排放标准》(GB 18918—2002)一级 A 标
准,其中TP执行≤0. 30 mg/L的限值。
本项目的设计进、出水水质如表 1 所示,其中,
进、出水pH均为6~9。
