Problems solved by technology

Although this bobbin can prolong the service life of the outer bobbin, the inner bobbin is often replaced due to the large degree of wear and tear, which cannot solve the problem of bobbin wear and prolong the service life of the bobbin, thereby lost production cost

Embodiment Construction

[0004] Printing and dyeing wastewater has a large amount of water, deep color, strong alkalinity, large changes in water quality, and high content of refractory organic pollutants. At present, printing and dyeing wastewater is generally treated by biochemical method, coagulation sedimentation method, coagulation air flotation method and activated carbon adsorption method. These methods have high investment costs, difficult management, and unsatisfactory decolorization effects and removal rates. In recent years, many research results and technical patents of electrochemical treatment of printing and dyeing wastewater have been reported, and they have been applied to wastewater treatment projects of printing and dyeing enterprises of various scales, and have received good results. Using micro-electrolysis to treat dye wastewater, the removal rate of CODcr is about 67%, and the decolorization rate is almost 100%. The results show that acidic wastewater is beneficial to the remov...

Abstract

The invention discloses an iron-carbon micro-electrolysis filler for treatment of printing and dyeing wastewater. The iron-carbon micro-electrolysis filler is characterized in that dyestuff wastewateris treated by utilizing a micro-electrolysis method, the removal rate of CODcr is about 67%, and the color removal rate is nearly 100%. Results show that acid wastewater contributes to removing the CODcr and removing the color, and acid wastewater with a pH value of 4 is selected; and the prolonged micro-electrolysis reaction time contributes to improving the treatment effect, while investment and operation cost can be increased, and the reaction time needs to be controlled to be 50 minutes.

Description

technical field [0001] The invention relates to the textile field, in particular to a textile bobbin. Background technique [0002] The world is developing and society is progressing. Since the Industrial Revolution, mechanical production has flooded people's social production activities, which have greatly developed social productivity. The textile industry has also developed rapidly, bringing benefits to people. The invention with the application number 01220683147.1 is disclosed Provided is a bobbin, comprising a tapered tube body (2), the internal shape of the tube body (2) matches the spindle of a textile machine, and the feature is that: the tube body (2) includes an inner tube body (4) and an outer tube body (6), the outer tube body (6) is detachably set on the inner tube body (4). The invention has simple structure and long service life. Although this bobbin can prolong the service life of the outer bobbin, the inner bobbin is often replaced due to its high degree ...
