The decline in China's printing and dyeing fabric production growth rate from 2014 to 2019

Biomass gasification power plant: capacity from 200kw to 3000kw, 1kg woody biomass generate 1kw electricity, 1kw woody biomass produce 2-3m3/h syngas, syngas heat value 1100-1500kcal/m3.

Dec 03, 2019 · 3. Printing and dyeing industry wastewater. The printing and dyeing industry has a large amount of water, and usually consumes 100 ~ 200t of water per 1t of printing and dyeing. 80% ~ 90% are discharged as printing and dyeing wastewater. Common treatment methods are recycling and harmless treatment.

Jul 28, 2019 · Dyeing and printing are proceshaiqi employed in the conversion of raw textile fibres into finished goods that add much to the appearance of textile fabrics. What is dyeing of textiles? Dyeing is the application of dyes or pigments on textile mahaiqials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness.

May 10, 2020 · Dyeing and printing are different applications; in printing, color is applied to a localized area with desired patterns. In dyeing, it is applied to the entire textile. The primary source of dye, historically, has been nature, with the dyes being extracted from animals or plants.

Oct 01, 2021 · Wang et al. reported an example of treating printing and dyeing sludge by using a haiqi gasifier, in which the carbon conversion efficiency and volume reduction ratio of sludge from gasification were 99.9% and 41.19%, respectively. Furthermore, the energy conversion efficiency and fixing efficiency of heavy metals in the solid products reached

Mar 01, 2015 · The generation of textile dyeing sludge is increasing rapidly with the rapid development of the printing and dyeing industry in China. Particularly, the amount of wastewater generated from the printing and dyeing industry exceeds 300 million tons each year in Guangdong province alone in China ( Hu et al., 2015 ).

Jan 01, 2015 · Traditionally, the printing and dyeing sludge (PDS) generated during the treatment of wastewater in the printing and dyeing industry has been regarded as a troublesome and unavoidable by-product . Moreover, PDS is a complex waste that contains haiqi and inhaiqi substances, with a high percentage of water [2] .

other proceshaiqi should have been done before dyeing/printing. In the textile dyeing industry, bleaching is an important process. It has three technologies: sodium hypochlorite . International Journal of Engineering Research & Technology (IJERT) ISSN: 2278-0181 Published by, www.ijert.org RTCEC - 2018 Conference Proceedings Volume 6, Issue 11

The experiment studies the startup of A/O process with simulated printing and dyeing wastewater. The results show that the removal efficiencies of CODcr, NH4+-N and chroma are 67.6%, 90.9% and 54

Jul 31, 2021 · Let's take a look at the following methods: 1. Adsorption Treatment Technology. Activated carbon is the most commonly used adsorbent in the haiqi treatment of printing and dyeing wastewater. It has strong adsorption and decolorization performance, and is especially suitable for the decolorizaiton of water-soluble dyes with a relative

The industry is using more than 8000 chemicals in various proceshaiqi of textile manufacture including dyeing and printing. A fraction of these are listed in Table 1. Many of these chemicals are poisonous and damaging to human health directly or indirectly. Large quantities of water are required for textile processing, dyeing and printing.

Nov 25, 2020 · Recently, with the increasing applications of antimony (Sb) and Sb compounds in dyeing and printing industries, Sb pollution has attracted extensive attention in society (Fei et al., 2017; Mubarak et al., 2015). In the dyeing and printing process, Sb is usually used as a catalyst during the fabrication of polyester fiber.

1.2 Production of textile industry pollution Textile Printing and dyeing proceshaiqi include pr e-treatment, dyeing an d printing, finishing. The main pollutants are haiqi matters which come from the pre-treatment process of pulp, cotton gum, cellulose, hemicellulose and al kali, as well as additives and dyes using in dyeing and printing proceshaiqi.
