Water resource has basic irreplaceable status and effect to human survival and development.The sustainable effective and safety and environmental protection of city water resource is supplied with, and be the lifeline of urban population existence and socio-economic development, yet therefore many water head sites has formed potential threat to the safety of self because having open characteristics.
Iterative method due to historical reasons and urban construction; the interlockings such as water head site and harbour, chemical industrial park, sewage draining exit; all there is hidden danger to some extent in the water head site of riverine each city 50%-80%; if in urban conservation area, be provided with sewage draining exit; have harbour or other enterprises, or intake is too near etc. apart from navigation channel.The potential problems that such layout is brought are, in case there have chemical plant, sewage draining exit or dangerous material harbour to occur to be unexpected, the burst pollution event is unavoidable, and city along the river's water head site will be on the hazard, thereby cause the crisis of supplying water.The burst pollution event may cause the heavy losses of the pollution of waterhead of municipal water seedbed and drinking water system within very short time, and may further trigger more serious urban safety problem, mishandlingly also can stay far-reaching sequelae.
Reply water source burst pollution accident, generally all cut off the water supply at present, for the city that alternate source is arranged, can enable the deposit water source, alleviates short-term water supply crisis, treats that the pollution of waterhead substrate concentration is reduced to below standard value, then reopen former water source.On the contrary, for do not have alternate source city, can only wait the pollution of waterhead substrate concentration to be reduced to standard value.But the pollution of waterhead substrate concentration reduces needs the regular hour, for a city, several hours lacks of water, all likely bring huge loss, more likely causes social turmoil, uneasiness.Due to developing rapidly of city, make land resources become precious, and the alternate source majority in city be take underground water as main, well-digging on the spot, be caving-in bash.In addition, the groundwater abstraction due to a large amount of, make surface collapse, and crack appears in ground, and building ftractures, collapses, and has a strong impact on the Security and development in city.Some places open up reservoir as " second water source, but due to gigantic project, the investment larger, the shortcomings such as water system complexity, neither a good measure.
Soil is various inorganic matters, organic matter and biological mixture.The various materials that form soil are maintaining mutual relation cleverly, and play an important role in the ecosystem.Physical property from soil, soil aperture is less, hole pipeline complexity, cause the soil permeability coefficient less, therefore the water above riverbed is penetrated into underground water source through riverbed needs a long time, and underground water source is safe can be the city normal water supply within this time, in addition, soil has certain suction-operated to pollutant, and this has further reduced the contaminated possibility of underground water.Biological and chemical angle from soil, microbe in soil has certain degradation, the time of staying of pollutant in soil is long, the amount of pollutant is relatively less, the geobiont bacterium colony is abundanter, measure more, so pollutant in the good degradation water of the energy of the microorganism in soil, add again some anion and cationic effect in soil, can react with pollutant generation redox, precipitation, complexing etc. in water, can make pollutant from harmful change into harmless, for underground water provides sound assurance as urban water resource.
Summary of the invention
For the defect existed in above-mentioned prior art, technical problem to be solved by this invention is to provide a kind of two-way water fetching device for emergent burst pollution accident, described this water fetching device can provide conventional water intaking, can when water source burst pollution accident occurs, normally fetch water again.
A kind of two-way water fetching device for emergent burst pollution accident of the present invention, comprise an emergent pipeline, the upper end of described emergent pipeline connects a three-way pipeline, the first pipeline of described three-way pipeline is connected with described emergent pipeline, the second pipe of described three-way pipeline is connected with a water pipeline, the 3rd pipeline of described three-way pipeline is connected with a water intake, between described water intake and described the 3rd pipeline, first valve is set, is provided with second valve between described the first pipeline and described emergent pipeline.
