According to environmental statistics, the textile industry ranked third among the 41 industrial sectors in the survey, with 2.37 billion tons of waste water.
Chemical oxygen demand discharge 277,000 tons, ranking fourth.
Ammonia nitrogen discharge 19,000 tons, ranking fourth.
The state-controlled section 972 of the top ten water system monitoring, Ⅰ ~ Ⅲ, Ⅳ ~ Ⅴ and substandard Ⅴ class section water quality ratio of 63.1%, 25.3% and 11.6% respectively.
The main pollution indexes are chemical oxygen demand (cod), five days biochemical oxygen demand (cod) and total phosphorus. Especially in the east, where economic development is fast, pollution is the heaviest. Strengthening environmental governance has come to a critical point.
At present, the country's access policy for printing and dyeing is more and more strict. The standard of indirect waste water discharge is raised to CODCr200mg/L, and even to CODCr60mg/L in sensitive areas. The country does not include printing and dyeing sludge in the hazardous waste list, but in the process of environmental management, printing and dyeing sludge is treated as hazardous waste; Waste gas, sludge and the elimination of backward everywhere is the threshold, not to increase investment enterprises sooner or later will be eliminated.
So far this year, more than 90 printing and dyeing enterprises in shaoxing have borrowed 1.66 billion yuan from Banks to finance environmental protection through the pledge of wastewater discharge rights.
From the national hazardous waste list, textile dyeing and finishing industry water pollutant discharge standards, to the environmental compliance guidelines for printing and dyeing enterprises, environmental pressure is forcing the industry to transform and upgrade step by step, and the reshuffle of printing and dyeing industry is intensifying.
In fact, China's current level of energy conservation, emission reduction and environmental protection is not low in the world, including the emission standards are higher than those of European and American countries.
The main reason is that our industrial agglomeration degree is very high, and a large number of enterprises gather in a small area. As a result of the cumulative effect, the impact on the environment is relatively large.
As the textile dyeing and finishing industry is a big water user, as well as a large sewage discharge, the development in many places has been restricted.
In order to promote advanced environmental technology and experience and accelerate the pace of energy conservation and environmental protection in the industry, China printing and dyeing industry association has been holding the "national energy conservation and environmental protection annual conference" since 2006.
Each annual meeting of environmental protection is to communicate and promote plants with respect to energy conservation and emission reduction problems commonly existing in the production process of enterprises and some key common technologies encountered in industrial transformation and upgrading.
In recent years, the technological level and product level of the entire printing and dyeing industry have been greatly improved, the proportion of advanced equipment in the industry has been continuously improved, and energy conservation, emission reduction, clean production and ecological security have been steadily promoted.
