在环保领域，苎麻废水堪称难啃的 “硬骨头”。苎麻生产废水有机物浓度超高，含有大量果胶、半纤维素等难降解物质，成分极为繁杂，处理难度呈几何级增长。并且，污水中的高浓度有害物质、复杂成分及特殊酸碱度，严重抑制微生物生长繁殖，可生化性差，常规微生物处理手段难以发挥作用。
In the field of environmental protection, ramie wastewater can be regarded as a "tough nut to crack". The concentration of organic matter in the wastewater from ramie production is extremely high. It contains a large amount of hardly degradable substances such as pectin and hemicellulose, and its composition is extremely complex, which makes the difficulty of treatment increase exponentially. Moreover, the high-concentration harmful substances, complex composition, and special pH value in the sewage severely inhibit the growth and reproduction of microorganisms, resulting in poor biodegradability. Conventional microbial treatment methods are difficult to play an effective role.
企业困境：旧工艺难达标
Enterprise Dilemma: The Old Process Struggles to Meet Standards
某苎麻生产企业长期受污水问题困扰。原污水处理系统中各构筑物间配合不畅，虽经厂领导多方协调，先后引入多家运维厂家调试，却始终未能突破水质达标瓶颈。面对日益严格的环保标准，厂领导深思熟虑后，经多轮考察评估，最终将污水运维重任托付给武汉碧清环保技术有限责任公司。
A certain ramie production enterprise has been troubled by sewage problems for a long time. In the original sewage treatment system, the structures did not cooperate smoothly. Despite the factory leaders' extensive coordination and the introduction of multiple operation and maintenance manufacturers for debugging, they still failed to break through the bottleneck of meeting water quality standards. Facing the increasingly stringent environmental protection standards, after careful consideration and multiple rounds of inspections and evaluations, the factory leaders finally entrusted the important task of sewage operation and maintenance to Wuhan Biqing Environmental Protection Technology Co., Ltd.
专业应对：组建团队深入研究
Professional Response: Form a Team for In-depth Research
受场地限制，难以进行大规模工艺改造，只能小修小补。武汉碧清环保技术有限责任公司接手后，迅速组建专业团队。团队成员全面考察污水处理系统的现有构筑物，重新绘制图纸，深入了解系统结构与运行状况。技术人员多次采集污水样本，在实验室开展大量实验，寻找最佳处理方案。并对原有系统进行改造。
针对微生物存活难题，研发团队另辟蹊径。深入研究污水成分，筛选适应力强的微生物菌群。同时优化处理环境，精准调控曝气时间与强度控制溶解氧。在不更换主体设备的情况下，升级关键处理单元。
Limited by the site, large-scale process transformation was difficult, and only minor repairs and adjustments could be made. After Wuhan Biqing Environmental Protection Technology Co., Ltd. took over, it quickly formed a professional team. The team members conducted a comprehensive inspection of the existing structures in the sewage treatment system, redrew the blueprints, and gained an in-depth understanding of the system's structure and operation status. The technicians collected sewage samples multiple times and carried out a large number of experiments in the laboratory to find the best treatment plan. They also transformed the original system.
To address the problem of microbial survival, the R&D team explored new approaches. They conducted in-depth research on the composition of the sewage and screened highly adaptable microbial flora. At the same time, they optimized the treatment environment, precisely regulated the aeration time and intensity to control dissolved oxygen. Without replacing the main equipment, they upgraded the key treatment units.
显著成效：水质达标贡献突出
Remarkable Achievements: Outstanding Contribution to Meeting Water Quality Standards

排水COD从400mg/l降至100mg/l以下，NH3-N从15mg/l降至1mg/l以下，运行稳定且排水水质远低于排放标准。
The COD of the discharged water has dropped from 400mg/l to below 100mg/l, and the NH3-N has decreased from 15mg/l to below 1mg/l. The operation is stable, and the quality of the discharged water is far lower than the emission standards.

经双方两个月协同攻坚，成效斐然。在苎麻厂领导全程支持下，不仅保障了调试期间生产与运维的有序衔接，还积极配合武汉碧清开展工艺优化。如今，在武汉碧清的精心运维下，原本不达标的出水如今稳定达标，各项污染物指标符合环保要求。微生物活性高涨，高效分解污染物，处理效果远超预期。这不仅解决了企业难题，也为当地生态环境改善作出重要贡献，彰显了武汉碧清的专业实力，为苎麻行业绿色发展提供了可行方案。相信未来，我司将在环保领域继续攻克更多难题。
After two months of collaborative efforts between the two parties, remarkable achievements have been made. With the full support of the leaders of the ramie factory throughout the process, not only has the orderly connection between production and operation and maintenance during the debugging period been ensured, but also active cooperation has been given to Wuhan Biqing in carrying out process optimization. Now, under the meticulous operation and maintenance of Wuhan Biqing, the effluent that originally failed to meet the standards now stably meets the standards, and all pollutant indicators comply with environmental protection requirements. The activity of microorganisms is high, and they decompose pollutants efficiently, with the treatment effect far exceeding expectations. This not only solves the problems of the enterprise but also makes an important contribution to the improvement of the local ecological environment. It demonstrates the professional strength of Wuhan Biqing and provides a feasible solution for the green development of the ramie industry. It is believed that in the future, our company will continue to tackle more problems in the field of environmental protection.
