摘 要：
With the development of detergent industry,the ecological impact of washing wastewater on xiangjiang river basin is becoming more and more serious.This article conducts qualitative or quantitative analysis of the pollution source of commonly used washing wastewater.In addition,the comprehensive pollution index COD emissions of washing wastewater is also studied.The article gets three conclusions accordign to the results.Firstlty,the in the content of refractory organic content in washing wastewater pollution sources reaches 20%.Although the contents of fluorescent whitening agent,preservative and flavoring ingredients is not high,their toxicities,such as strong excitant,carcinogenic teratogenicity,are not allowed to be ignored.Secondly,the concentration of 1.0g/L washing wastewater COD emission is 6to 16 times over the first-level A standard of urban sewage treatment plant pollutant emission;COD annual emissions of a city that with population of 10 million is 25- 65 thousands tons.Thirdly,the article points out that how to correctly guide residents to reasonably choose and use detergent and how to guide enterprise to develop washing products of high effeciency and low emission are of great significance.
