小印染高浓度有机废水污染防治技术

10年来，笔者一直从事于治理工业废水的研究工作，重点是丝绸染色废水以及高浓度无毒有机废水，曾经或即将应用于生产的技术有丝绸印染废水与炼染废水、缫丝厂的淡头废水、乳制品厂的麦乳精及其它乳制品的废水、薯于酒精发酵废醪以及井冈霉素突发性倒罐液等．分别加以说明．     

高浓度精炼废水的治理

一、前言丝绸行业的精炼废水排放量不大,日排量在20—80吨左右,但其CODcr值很高,一般在一万——五万mg/l范围,且难以生化释解。     

丝绸废水处理工艺研究和工程建设情况

论述了格栅池、筛滤机、调节池、气浮池、生物接触氧化池、二次沉淀池和氧化脱色池相串联的处理工艺对丝绸生产废水的处理效果。结果表明，经过二级生化处理后，各项主要废水水质指标都达到了废水排放标准。而且，加次氯酸钠氧化可进一步改善废水水质，可为废水回用和节约地下水资源提供参考。     

China-Indian Silk Trade： Current Production and Future Prospects

As an important traditional labor-intensive industry of both India and China, the cocoon silk industry has long made great contributions to the ecological environment protection, rural economic development and the increase in export income of both countries. India is not only a very important cocoon silk trading partner, but an important production competitor of China. In recent years, there has been a large increase in the production and trade of the cocoon silk between China and India; however, China relies heavily on Indian market, which leads to a tendency of further deterioration in the silk trade environment between both countries. The present article makes an empirical study of the cocoon silk resources of the two countries and the scale, product mix and market structure of China-Indian silk trade from 2001 to 2007. Overall silk trading volumes from China to India and market concentration rate are on the increase because of the superiority of Chinese cocoon silk production over that of India. Owing to scattered market share and export that mainly focused on raw materials product, there has been a phenomenon of price reduction and quantity increase. India carries out fierce competition with China in the international market and even imposes antidumping sanction on Chinese silk, which are key factors restricting further increase between China-India trade. Based on the abovementioned facts, the authors aim to put forward suggestions for steadily developing the production and trade of China＇s silk.     

“化学混凝—好氧—精滤”相串联工艺在丝绸印染废水处理中的应用

丝绸印染废水污染严重,采用单级射流曝气往往不能达标。本文作者采用“化学混凝—好氧—精滤”相串联工艺,对达县地区丝绸厂原污水处理站的单级射流曝气工艺进行改造,在不增加设备和构筑物的情况下,取得了良好的运行效果。为我国同类污水站的改建提供了成功的建设经验。     

仿真丝绸印染水污染物衡算

从仿真丝绸印染所独需的碱减量生产工艺出发，利用生产工艺的几个参数，对碱减量工艺产生的水污染物进行了衡算剖析。应用类此实测法对精炼、印染等工段产生的一般排水也作了概述。为仿真丝绸印染项目环境影响评价中的水污染物产生量计算提供借鉴。     

投资环保 企业增效——南部县绿神丝绸有限责任公司

南部县地处川北，座落在嘉陵江畔，人畜饮用水部分从嘉陵江中取用，县内深丘地貌较多，部分乡镇淡水资源溃乏，因此保护好嘉陵江淡水资源迫在眉睫。在县域经济高速增长的今天，用更多的精力协调好经济的增长与环境保护的关系是整个社会刻不容缓的责任，大力发展环保型循环经济是南部县企业的义务。
