Heavy pollution enterprises are facing elimination transformation containing electroplating industry
Yesterday is world environment day.
In the environmental protection department of the day before yesterday announced the 2012 "state of the Environment Bulletin" shows China, Pearl River Estuary and Bohai Bay, Yangtze River Estuary, Hangzhou bay were rated as very poor water quality.
Reporter discovered through nearly 20 years of estuary water quality, water quality of the Pearl River Estuary has been 10 consecutive years stable at inferior to four categories of seawater is the worst level in more than 20 years, but the overall trend is going downhill.
The reporter investigates discovery, pollution remediation of the Pearl River water, will also make heavy polluting enterprises in the Pearl River Delta is facing enormous pressure of rising costs, will accelerate the elimination of the pace of transformation.
More than half of the four bad water quality, serious pollution for 10 years
Schematic from Guangdong Province offshore water quality picture is not difficult to find, in the center of the Pearl River Estuary was deep brown triangle.
This sees impressively color, corresponding with the worst water quality inferior to four categories.
According to the environmental protection department reported yesterday, the 9 main bays, the Yellow River Beibu Gulf slobber quality, good water quality, the Liaodong Bay, Jiaozhou Bay and Minjiang export poor water quality, Bohai Bay, Yangtze River Estuary, Hangzhou Bay and the water quality of the Pearl River estuary.
Compared with the previous year, the Yellow River Estuary and Minjiang estuary water quality changed for the better, the other bay water basically stable.
Water quality of the Pearl River Estuary exactly have much difference?
According to the monitoring of marine water quality standard, the lowest level of water quality is inferior to four categories of water (River and surface water quality standards are different, the worst level is inferior to five categories).
The reporters found from the comparison chart of the Ministry of environmental protection, inferior to four categories of seawater pearl River Estuary in 2012 more than half, but not to the six into.
Comparison of water quality with the known the three Gulf as "poor", the Gulf of Hangzhou for almost all inferior to four categories of the sea, the Gulf of Bohai and the Yangtze River mouth inferior to four categories accounted for about 70% of the sea.
The mouth of the Pearl River in the "very poor", is a better one.
In addition, interestingly, from this point of view, the Pearl River Estuary seawater composition except the four bad water, the rest are is a kind of sea water and two kinds of seawater, and no transition three or four class water "".
The Marine Fisheries Bureau recently issued the "2012 Marine Environment Bulletin", Guangdong Pearl River mouth is still beyond the local harbour area, central area inferior to four categories of water, the main pollutants are inorganic nitrogen and active phosphate.
If the change trend, the mouth of the Pearl River situation is even more worrying.
A check of the 1989 to 2012 the Ministry of environmental protection or the Marine Department of state of the Environment Bulletin, water quality of the Pearl River Estuary basically showed a gradual increasing trend.
And in the Pearl River Estuary have four bad water quality has lasted ten years.
Half of the sea outfall concentrated in Pearl River Delta
And the Pearl River Estuary in the water quality of the "bottom" contrast, environmental protection department Bulletin shows, last year, water quality in the Pearl River Basin and the Pearl River Basin is superior, 54 state-controlled sections, ~, ~ and bad water quality section respectively 90.7%, 5.6% and 3.7%.
The 18 state-controlled sections, to water quality section ratio up to 94.4%.
Why do the dirty water in the Pearl River mouth to show special preference to?
Provincial Oceanic and Fishery Bureau analysis, according to the monitoring data in recent 10 years, comparative analysis, to maintain the stability of the Pearl River estuary area and degree of pollution on the whole, but "the main problem facing eutrophication is still in the Pearl River Estuary water".
Among them, the most downstream of the Pearl River Delta to the sewage situation River can not be ignored.
The Marine Department experts said, the Pearl River Delta is densely populated, economically developed, accepted along industrial, planting, animal husbandry and sewage through the Pearl River Estuary with runoff into the Pearl River Estuary constitute pollution, "the Pearl River Estuary sea pollution total amount is 663300 tons per year, the main pollutants into the sea (index) is the chemical oxygen demand, nutrient salt."
"Bulletin" 2012 marine environment also support this point of view, the 82 into the sea outfall, distribution of coastal in the Pearl River Delta region has 41, accounting for half of.
The Pearl River Delta coastal waters to accept the sewage 1 tons, is the main receiving waters of the sewage into the sea, accounting for 42.04% of the province.
In addition, some tributaries of the water quality of the Pearl River estuary into poor, also increased the pressure of pollution in the Pearl River estuary.
