In extensive network Beijing on July 29 message (reporter Du Ximeng) the sound that occupies China " news freely " report, recently, a report about water, the issue comes the quality safety that lets water in public line of sight again. Search in many media " the river that can swim " while, this reports, pass as a result of our country's at present existent industrial blowdown standard low, bringing about even if is processing hind obtains the indharrison hot spring public poolustrial foul water that discharges a standard, still compare bad Ⅴ kind water quality is poorer. Each days, these sewage are being discharged to take of great capacity of river river lake directly, accentuated badly water system pollution.
According to our country current and active " standard of quality of surface water environment " , the poorest, the water quality that has lost water system function is bad Ⅴ kind, among them a main index is, the chroma of chemical oxygen demand in water quality exceeds 40 milligram / every litres. But it is such water, if be the eduction in the sewage draining exit from the factory, it is qualification amounts to mark instead, in can discharging surface water directly.
Industrial blowdown standard and concept of standard of water system quality are promiscuous
According to the statement that the media before this reports, sewage of industry of industry of our country majority discharges water quality of surface water of standard far outclass to ask. Like our country " content discharges papermaking industry water pollution standard " regulation, chemical oxygen demand discharges chroma to build an enterprise to be 90mg/l in the water pollution thing that waste paper makes oar papermaking enterprise discharge. " spin catchs entire industry water pollution content discharges a standard " the level is higher, chroma of chemical oxygen demand should be controlled only can discharge continuously in 100mg/l. The conclusion that reachs at this point is, our country is prevented in water pollution accuse to go up made effort because blowdown level is too low,hit water to float, because of a large number of eligible sewage discharge can let " good water " also become "spring pool bad water " . To this, zhao Ying of director of department of standard of science and technology of environmental protection ministry civilian explanation, this reasoning process is pleasant to the eye be like reasonable, but exist to measure a level to industrialwatch case manufacturer blowdown standard and water constitution however among them of two concepts promiscuous.
Zhao Ying civilian: Discharging the basis that metric system decides is the technical accessibility of this industry and economic feasibility, the formulate basis of environmental quality standard is tutelar body health and zoology environment, of environmental quality and contaminant discharge gross and environmental capacity to concern. For instance, of the paper mill discharge a standard making when editing, want to be built where withthe most popular watch casesout the consideration, if be by the side of a river, have land of a drinking water source, that environment affects an evaluation to won't allow it to build.
Want blowdown to pollution controls gross to ensure environmental quality amounts to mark only
Zhao Ying civilian explains further, in the enterprise pollution discharges the relation that amounts to mark with environmental quality to go up, our country is mixed at present the general way on the world is same, it is to pass gross pilot method to ensure the most popular north face shirtsblowdown gross does not exceed environmental capacity, ensure environmental quality of place amounts to mark thereby.
Zhao Ying civilian: The standard that industrial sewage discharges is equivalent to every overcoming the nicotine content in cigarette, annulus is judged is this house so big, I allow how many person to smoke in this. The harwatch casesm of every cigarette falls lowlier to had been jumped over.
Zhao Ying civilian is straight-out, should smoke only ill health, same, want blowdown to be able to have pollution only. In real life, we need not smoke, but do not want industry impossibly. Below this kind of circumstance, manage all department to come with respect to need environment monitoring. brass faucet
Zhao Ying civilian: Discharging a standard is a link in environmental management, include annulus to judge system of licensing of system, blowdown to form the chain of an environmental management with its form a complete set. The enterprise is built in downtown, the likelihood should be carried out very severely, if be built in an unmanned area, final also cannot low pass occupation standard.
Standard of our country environment is close to developed country level to discharge standard and quality award bmodern dining chairsrigadier to conform stage by stage
And low to the industrial blowdown standard that is oppugned by media, the issue winorton internet antivirusth small cost, zhao Ying civilian chooses to talk with the number, come round to look from eye, number of level of our country environment already exceeded 1400, each industry discharges a standard to approaching level of developed country level stage by stage on the whole.
Zhao Ying civilian: Our country " 915 " during the industry discharges a standard not to have one exception is to add severe, at present a lot of occupation standard had been been close to or reach developed country level, cannot say current level is very loose still so. But how does occupation standard father to discharge mineral water impossibly also again, if such, our water affirmation is good, the problem is short of.
Put forward to partial expert nevertheless, "Develop in a few economy but area of environmental look hidebound, arrange water pollution thing standard and standard of water environment quality to conform as soon as possible " proposal, zhao Ying civilian also very self-identity, in fact, such principle also has applied on the blowdown management of a few places.
Zhao Ying civilian: Such Beijing north is short of water city, do not have environmental capacity, so Beijing asks the enterprise discharges the level that must reach surface water directly. If the river had been polluted, so be about on link of environmental impact assessment from tight control.
Prospective enterprise will carry out different level
Zhao Ying civilian still discloses, in abroad many environments run the country with perfect legal system, many free watch caseenterprises need to discharge blowdown licence of the standard to ask according to disparate executive outclass industry, the system of this domain perfects future will be the direction that our country water pollutbrass faucetion prevents and cure hard. And at present, one affects the important level of safety of water quality of our country surface water, in be being made, the earliest likelihood comes out next year.
Zhao Ying civilian: We are current and preliminary the hope is in release inside year this year ask for an opinion to stalk of grain, strive for next year to be released formally. We consider is, new standard offers ground of drinking water source alone, water system eutrophication evaluation and water system function evaluate departure, the basis evaluates the purpose of the evaluation, classify ground implements the provision of different level.
