广东环保水处理印染污水处理地埋式

广东东莞印染污水处理

产品分类:印染污水处理工程

项目名称:某纺织企业污水处理工程

治污种类:印染废水及日常污水处理

处理规模:日处理量400

执行标准:综合排放标准

处理工艺:采用混凝沉淀+水解酸化+好氧生物处理的处理工艺

项目简介:印染污水处理工程,该工程处理水量为400m3/d,处理效果达到国家排放标准。

印染污水处理特点及难点

印染废水主要由退浆废水、煮炼废水、漂白废水、丝光废水、染色废水和印花废水组成,具有以下特征:水量大、有机污染物含量高、碱度和pH值变化大、水质变化大;可生化性能差,废水m(BOD)m(COD)值一般在20%左右:色度高,有时可达4000倍以上;印染行业中,PVA浆料和新型助剂的使用,使难生化降解的有机物在废水中的含量大大增加。若未处理或处理不当即排入水体或用于灌溉,将会污染环境,影响人们的身体健康。

解决方案及技术工艺

根据对该纺织企业的实际考察,通过现场调查和资料查找,以及当地市环境监测站监测数据综合分析,我公司技术组为该纺织企业制定了对应的工艺流程,有效的解决了该纺织企业的印染废水和生活污水的处理问题。

针对印染废水悬浮物较高及色度较深的特点,步选择混凝沉淀,去除悬浮物和色度,使出水的水质指标相对稳定,同时印染废水中含有大量的溶解度较好的环状有机物,其生物处理效果一般,因此选择酸化水解工艺将高分子环状有机物降解为小分子和破环,提高废水的生化处理效果,通过酸化水解工艺后,提供充足的氧源的情况下,在好氧生物的作用下,大部分有机物被消耗,致使出水的水质指标稳定,对于还有少量颜色的废水很难通过混凝沉淀及生物处理脱色,为保险起见,在生物处理后增加化学氧化系统,对印染废水处理很有必要。

处理后的效果

本次为该化工企业设计的污水处理系统出水水质较好,主要水质指标可以达到排放标准,能很好的适应进水水质不稳定,系统出水可达到综合污水排放标准,有效的解决了出水色度不达标的问题。

Printing and dyeing wastewater treatment in Dongguan, Guangdong

Product classification: printing and dyeing wastewater treatment project

Name of the project: sewage treatment project of a textile enterprise

Pollution control types: printing and dyeing wastewater and daily sewage treatment

Processing scale: daily processing volume of 400 tons

Implementation standards: integrated first level emission standards

Treatment process: the treatment process of coagulation sedimentation + hydrolytic acidification + aerobic biological treatment

Project introduction: printing and dyeing wastewater treatment project, the water treatment of the project is 400m3/d, the treatment effect reached the national first level emission standards.

Characteristics and difficulties of treatment of printing and dyeing wastewater

Printing and dyeing wastewater by desizing wastewater, scouring wastewater, bleaching wastewater, mercerizing wastewater, dyeing wastewater and printing wastewater which has the following characteristics: large quantity, high content of organic pollutants, alkalinity and pH value changes, changes in water quality; biochemical performance, wastewater m (BOD), m (COD) value in general about 20% color high, sometimes up to more than 4000 times; the printing and dyeing industry, the use of PVA slurry and new additives, the organic matter content in refractory wastewater is greatly increased. If they are not treated or treated properly, they are discharged into the water body or used for irrigation, which will pollute the environment and affect the health of the people.

Solution and technical process

According to the actual investigation of the textile enterprises, through on-site investigation and information search, and the local municipal environmental monitoring station comprehensive monitoring data analysis technology, our company has established a group process corresponding to the textile enterprises, effectively solve the textile enterprises in the printing and dyeing wastewater and domestic sewage treatment problems.

According to the characteristics of high chroma and suspension dyeing wastewater deep, first step coagulation, the removal of suspended solids and chroma, the water quality indexes of the effluent is relatively stable, and the printing and dyeing wastewater contains a large number of good solubility of cyclic organic compounds, the biological treatment effect, so the choice of hydrolysis acidification polymer compounds degradation of the small molecule and broken ring, improve the biochemical effect of wastewater treatment, through hydrolysis acidification, providing a source of oxygen sufficient conditions in aerobic biological effect, most of the organic matter is consumed, the water quality index of effluent was stable, and a small amount of color for wastewater is very difficult by coagulation and sedimentation biological treatment and decolorization, for insurance purposes, increase the chemical oxidation system in biological treatment, it is necessary for the printing and dyeing wastewater treatment.

Effect after treatment

This is the design of chemical enterprise wastewater treatment system is better, the main quality index can meet emission standards, good adaptability to water quality is not stable, the effluent can reach the comprehensive sewage discharge standards, effectively solves the color of substandard problem.

Jining Tian Tong Shui processing equipment Co., Ltd. is located in the hometown of Kong Meng, the hometown of Zeng Zi, in Jining City, Shandong province. The company specializes in water treatment equipment such as wastewater treatment station, waste water treatment process, waste water treatment equipment, industrial waste water treatment equipment, water treatment equipment, domestic wastewater treatment equipment, environmental waste water treatment equipment and so on.
