摘要
文章以铸造工厂为调研对象,为了合理处理企业排放的废水,制定水环境质量监测计划,建立废水处理系统,分析该工厂铸造工艺及监测废水排放情况。通过检测可知废水中主要包括COD_(Cr)、BOD_(5)、SS、氨氮、动植物油、石油类、氟化物等污染物。通过废水处理系统的多层次废水处理措施,实现对各类污染物的合理去除。结果表明:出水中各项指标的去除率达到92%、93.74%、96%、90.24%、96.5%、96%、82.48%。处理系统的出水水质达到城市绿化限值和环保排放标准,确保了废水处理的良好效果。该措施有助于铸造工厂在实现废水可持续处理的同时,为铸造工业生产与环境的和谐共存、管理风险、确保铸造企业合规运营提供了有力支持和决策依据。
This article takes a casting factory as the research object.In order to reasonably treat the wastewater discharged by the enterprise,a water environment quality monitoring plan is formulated,a wastewater treatment system is established,and the casting process and monitoring of wastewater discharge in the factory are analyzed.Through testing,it is known that the wastewater mainly contains pollutants such as COD_(Cr),BOD_(5),SS,ammonia nitrogen,animal and vegetable oils,petroleum,fluoride,etc.By implementing multi-level wastewater treatment measures in the wastewater treatment system,reasonable removal of various pollutants can be achieved.The results showed that the removal rates of various indicators reached 92%,93.74%,96%,90.24%,96.5%,96%,82.48%,in the effluent.The effluent quality of the treatment system meets the urban greening limit and environmental discharge standards,ensuring good results in wastewater treatment.This measure helps casting factories achieve sustainable wastewater treatment while providing strong support and decision-making basis for the harmonious coexistence of casting industry production and environment,risk management,and ensuring the compliant operation of casting enterprises.
