摘要:

制革及毛皮加工废水属于高浓度难降解有机工业废水,具有排水量大、水质水量不均、污染物高及成分复杂等特点,给废水处理带来极大的难度。以河南省新乡市某皮革企业废水处理工程为例,根据制革及毛皮加工废水的特点,将含铬废水、含硫废水、脱脂废水进行分质预处理再与其他废水混合进行综合处理,出水水质能够满足相关排放标准的要求。

关键词: 制革及毛皮加工废水, 分质预处理, 综合处理

Abstract:

Tannery wastewater belongs to high-concentration refractory organic industrial wastewater, which has the characteristics of large water volume, uneven water quality and quantity, high pollutants and complex composition, which brings great difficulty to wastewater treatment. Taking a wastewater treatment project of a tannery enterprise in Xinxiang City, Henan Province as an example, according to the characteristics of tannery wastewater, the chromiumcontaining wastewater, sulfur-containing wastewater, and degreasing wastewater were pretreated and mixed with other wastewater for comprehensive treatment. The water quality could meet the requirements of relevant emission standards.

Key words: tannery wastewater, diversion pretreatment, comprehensive treatment
