In order to strengthen environmental supervision, the Ministry of Environmental Protection has used high-tech means such as drones, unmanned ships, satellite remote sensing, and big data. Environmental big data Satellite remote sensing map Drone Unmanned boat On April 21, 2017, the Ministry of Environmental Protection held a regular press conference in April to inform the national environmental supervision and law enforcement in the whole year of 2016 and the first quarter of 2017, and introduced the next work arrangements. In 2016, a total of 137,800 environmental violation cases were investigated and handled, and 124,700 administrative punishments were issued. The total amount of fines and penalties was 6.633 billion yuan. The number of administrative punishment cases in Guangdong, Beijing, Jiangsu and Zhejiang exceeded 10,000. In the first quarter of 2017, the total number of cases involving the applicable provisions of the Environmental Protection Law nationwide was 4,987. Among them, there were 224 consecutive punishments on a daily basis, with a fine of 263.75 million yuan, 2,190 cases of seizure and seizure, 1,228 cases of production suspension, and 958 administrative detentions, involving 387 cases of criminal transfer to public security organs. In order to strengthen the application of science and technology in environmental supervision and law enforcement, and promote scientific and technological law enforcement, the Ministry of Environmental Protection has used high-tech means such as big data, "Internet +", cloud computing, satellite remote sensing, drones, unmanned ships, etc. to monitor environmental pollution 24 hours a day. Happening. In the Beijing-Tianjin-Hebei region, hotspot grids are divided according to 3km×3km, and hotspot grids with high air pollution levels are regularly screened and sent to relevant local governments and environmental protection departments to implement precise law enforcement.
Old
VAT dye VAT dye, insoluble in water, in the alkaline solution by sodium
dithionite reduction processing powder (insurance), and make the fiber
dyeing dye. Its fast and washing fastness especially, can be used for
cotton, linen, viscose, whalen fiber dyeing and printing, etc.
In
the molecular structure of VAT dye excluding sulfonic group, carboxylic
acid base, such as water soluble groups, insoluble in water, therefore,
cannot be directly dyed; The molecular conjugated double bond systems
containing at least two carbonyl, interaction with insurance powder in
the alkaline solution, carbonyl reduction into hydroxyl, become water
soluble compounds ─ ─ the leuco body. Is leuco body has affinity to
fiber, fiber after adsorption, oxidized by air or other oxidants, leuco
body back for VAT dye fixation on fiber staining. Leuco body staining
method shortcoming is dye into the fibers not easily, if the suspension
pad dyeing, the reduction of the outstanding dye made from suspension
solution, borrow machine rolling pressure make dye fine, evenly
distributed on the dyed fabric treated with insurance powder and make
dye reduction by fiber adsorption, good is thicker and uniform can be
obtained by the oxidation dyeing effect.
Its
chromatographic is full, bright color, soaping, tanning fastness are
high, but because the price is more expensive, some yellow, orange and
other color with photosensitivity brittle damage phenomenon, make its
application is limited by certain.
Because Vat Dyes does
not dissolve in water, so the side effects of it on the human body easy
to control, more safe and convenient for environmental protection, but
its cost is generally high.
