摘要:
为解决苏州市某工业开发区内食品及印染织机废水水质复杂、建设用地受限、资金少等难题，污水处理厂设计建设了两套相对独立、单元构筑物管线又可灵活进行调度的工艺方案。两套废水处理主体单元均为厌氧水解池+一体化AAO生化沉淀组合池+絮凝沉淀池+滤布滤池，其中通过前置气浮池对印染喷水织机废水中的油状乳浊液进行预处理。该污水厂设计规模为3×104 m3/d，出水水质指标全面达到《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》（DB 32/1072—2018）中太湖流域一、二级保护区内主要水污染物排放限值要求，达标尾水再生回用于开发区内喷水织机生产过程。通过尾水的再生回用，不仅缓解了市政管网的供水压力，降低了企业的生产成本，同时也吸引了相关用水需求的企业入驻，具有一定的示范效应。
Abstract:
In order to solve the problems including complex wastewater quality, limited construction land and capital shortage from food, printing and dyeing loom wastewater in an industrial development zone in Suzhou, the sewage treatment plant has designed and constructed two sets of relatively independent processes with flexible scheduling of unit structures and pipelines. The main units of both sets are anaerobic hydrolysis tank, integrated AAO biochemical sedimentation combined tank, flocculation sedimentation tank, and filter cloth filter, wherein the wastewater from printing and dyeing water jet loom is pretreated to remove the oily emulsion by pre-air flotation tank. The designed capability of the sewage plant is 3×104 m3/d, and the effluent fully meets the discharge limits of the primary and secondary protection zones in Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industrial of Taihu Area (DB 32/1072-2018). The qualified tail water is reclaimed in the production process of water jet looms in the development zone. Not only does the reclaimed tail water alleviate the water supply pressure of municipal pipe network and reduce the production cost of enterprises, but also it attracts enterprises with relevant water demand to settle in, which has certain demonstration benefits.
