本文通过比较印度蒂鲁普尔和坎普尔的案例，揭示零液体排放标准下小企业因依赖共享处理厂而承担合规成本，建议以实测排放量判定合规并精准追责。
AI 中文摘要
许多国家要求工厂回收几乎所有的废水，并且不向河流排放任何废水，这一标准被称为零液体排放（ZLD）；在印度，法院已将其强加于纺织和皮革集群。然而，当执法收紧时，小企业关闭，而较大的污染者往往能坚持下来。本文探讨了原因，比较了已经发生关闭的蒂鲁普尔与正在进行关闭的坎普尔贾杰毛制革厂。小企业依赖它们无法控制的共享处理厂。随着这些工厂利用率不足，成本上升，性能下降，拥有内部处理设施的企业更能承受执法压力。由于合规性是根据设备所有权而非实测排放量来判断的，工厂故障被归咎于成员企业。最后一步的证据最为充分，而前面的环节仍具有提示性。本文建议根据实测排放量来判断合规性，并在关闭前确定是工厂还是企业出了问题，以便执法针对污染，而不是针对最无力承受污染的企业。
英文摘要
Many countries require factories to recycle almost all their wastewater and return none to rivers, a standard called zero liquid discharge (ZLD); in India, courts have imposed it on textile and leather clusters. Yet when enforcement tightens, small firms close while larger polluters often endure. This paper asks why, comparing Tirupur, where closures have already occurred, with Kanpur's Jajmau tanneries, where they are ongoing. Small firms depend on shared treatment plants they do not control. As these plants become underused, costs rise, performance declines, and firms with in-house treatment are better able to withstand enforcement. Because compliance is judged by equipment ownership rather than measured discharge, plant failure is attributed to member firms. This final step is the best evidenced, while the earlier links remain suggestive. The paper recommends judging compliance by measured discharge and determining whether the plant or the firm has failed before closure, so enforcement targets pollution rather than the firms least able to absorb it.
