摘要
酸性染料企业生产中存在资源利用率低,废水、污染物产生量大等环境问题,目前采用的传统末端治理技术已不能适应环保要求逐渐提高的新形势,而清洁生产是从单纯依靠末端治理逐步向全过程控制方向的一种转变,是酸性染料企业防治污染的最佳途径之一。通过对某酸性染料企业的清洁生产水平分析,提出清洁生产整改方案。方案实施后,单位产品综合能耗下降0.0147 t ce/t,单位产品新鲜水用量减少1.7 m 3/t,单位产品废水产生量减少17.25 m 3/t,单位产品危险废物产生量减少0.12 t/t,单位产品化学需氧量产生量减少5.68 kg/t,清洁生产水平得到显著提高。
There are environmental problems in the production of acid dyes,such as low resource utilization rate and large amount of wastewater and pollutants.At present,the traditional terminal treatment technology used can no longer adapt to the new situation of increasing environmental protection requirements,and cleaner production is a transition from relying solely on end treatment to the control of the entire process.It is one of the best ways for acid dye companies to prevent pollution.This paper proposes a cleaner production rectification plan by analyzing the cleaner production level of an acid dye enterprise.After the implementation of the plan,the comprehensive energy consumption per unit product decreased by 0.0147 t ce/t,the fresh water consumption per unit product decreased by 1.7 m 3/t,the waste water production per unit product decreased by 17.25 m 3/t,the amount of hazardous waste produced per unit product is reduced by 0.12 t/t,the chemical per unit product the amount of oxygen demand is reduced by 5.68 kg/t,the level of cleaner production has been significantly improved.
