The Textile And Dyeing Industry Is The First To Make Pollution Control.

Shaoxing

The work of environmental rectification has not yet ended.

It's coming again.

The environmental protection tax legislation has started, which means an important step towards the implementation of the green tax. Maybe in the next few years, the textile printing and dyeing industry, which is the first to tackle pollution, is worried about how to pay the environmental tax.

On January 26, 2016, the general office of the State Council sent a letter to the general office of the NPC Standing Committee on the resolution and consideration of the 2014 final accounts.

The general office of the State Council said that at present, the 18 types of taxes in China, including personal income tax, enterprise income tax and vehicle and vessel tax, have been legislated. The real estate tax and environmental protection tax have already started legislation, and actively cooperate with the Legislative Affairs Office in completing the Draft Environmental protection tax law and reporting to the State Council for deliberation.

The environmental protection tax legislation has started, which means an important step towards the implementation of the green tax. Maybe in the next few years, the textile printing and dyeing industry, which is the first to tackle pollution, is worried about how to pay the environmental tax.

From the point of view of the object of tax collection, the environmental tax is classified according to the key monitoring (sewage) taxpayers and non key monitoring (sewage) taxpayers.

The so-called key monitoring (sewage) taxpayers refer to the key monitoring enterprises of thermal power, iron and steel, cement, electrolytic aluminum, coal, metallurgy, building materials, mining, chemical, petrochemical, pharmaceutical, light industry (brewing, paper making, fermentation, sugar, vegetable oil processing), textile, leather and other 14 key polluting industries, taxpayers and other sewage industries.

1, the greatest harm is waste water.

Wastewater is the most important environmental problem in the textile industry.

Textile enterprises are one of the industrial departments with large water consumption and large displacement.

Textile wastewater mainly includes five types: printing and dyeing wastewater, chemical fiber production wastewater, wool washing wastewater, hemp degumming wastewater and chemical pulp pulp wastewater.

Printing and dyeing wastewater is the main source of pollution in the textile industry.

According to incomplete statistics, domestic printing and dyeing enterprises discharge about 300~400 t of wastewater per day, and the amount of waste water produced by printing and dyeing factories is 100 t per 3~5 m.

The waste water contains the entrainment material of fiber raw material, and the slurry, oil, dye and chemical aid used in the process. It has the following characteristics: (1) the COD change is large, the high time can reach 2000~3000 mg/L, and the BOD is also as high as 2000~3000 mg/L.

(2) pH is high, such as sulphur dye and vat dye wastewater pH can reach more than 10.

(3) high chromaticity, high organic content, large amount of dyes, auxiliaries and slurry.

(4) the change of water temperature and water volume is large. Due to the change of processing variety and output, the water temperature can generally be above 40 C, thus affecting the treatment effect of wastewater.

2, sewage.

Traditional printing and dyeing processes produce a large amount of toxic sewage. After processing, some toxic dyes or processing aids on the waste water have a direct impact on human health.

Such as azo dyes, formaldehyde, fluorescent whitening agents and softeners are allergenic; polyvinyl alcohol and polypropylene size are not easily biodegradable; chlorine bleaching agents are heavily polluted; some aromatic amine dyes are carcinogenic; dyes are harmful to heavy metals; formaldehyde containing various finishing agents and printing auxiliaries are toxic to human body.

3, air pollution.

According to the data of 2011, the exhaust gas from the textile industry mainly comes from about twenty thousand boilers in the industry. The total steam capacity of these boilers is about 60 thousand T, of which 85% of the total number of boilers is up to standard.

Most of these boilers use coal (including some raw coal) as fuel, which contains a certain amount of sulfur, which emits a lot of combustion waste gas, sulfur dioxide and soot in the combustion process, which pollutes the environment.

Another main source of textile waste gas comes from the textile production process.

The exhaust gas from the textile industry mainly comes from the production process of chemical fibers, especially viscose fibers.

A large amount of carbon disulfide and hydrogen sulfide are used as synthetic raw materials in chemical fiber production. Due to incomplete process and process control, a part of exhaust gas is directly discharged.

4, noise pollution.

Noise pollution is one of the serious problems existing in the textile industry, especially in the cotton textile industry. Because of the large number of shuttle looms used in cotton mills, the noise level inside the factory is 90~106 dB, while the maximum allowable value of noise for human ears is only 85 dB.

The actual situation of noise detection in cotton textile factories in some parts of China shows that the environmental noise in the textile workshop is on average 100~105 dB.

Judging from the tax standard of the draft, following the notice on adjusting the standard of sewage charges collection and so on, the proportion of collection has been further raised after raising the sewage charges.

This standard has raised water pollution and air pollutants to 1.4 yuan and 1.2 yuan respectively, and the proportion of most pollutants has increased 1 times. At the same time, the standard of distinguishing heavy metals and other pollutants is emphasized.

In general, the textile industry is highly dependent on resources and energy.

According to statistics, China's textile industry energy consumption and water consumption accounted for about 4% of the total industrial energy consumption, accounting for 2.4% of the total water consumption.

Waste water also accounts for a large proportion, accounting for about 12% of the total industrial wastewater discharged by the whole country.

Textile industry is a basic industry in the textile industry. It shoulders the heavy burden of energy saving and emission reduction tasks.

If China's environmental protection tax is positioned as energy tax, traffic tax, pollution tax and resource tax, it will have a certain impact on the development of the textile industry.

Once the environmental protection tax is legislated, its implementation will be irresistible.

For textile enterprises, the most effective way is to conform to the trend of history, actively carry out energy conservation and emission reduction work, reduce energy consumption and reduce pollutant emissions, so as to reduce the cost of environmental protection tax.
