A kind of middle water reuse apparatus

Technical field

The utility model relates to sewage treatment area,, especially a kind of middle water reuse apparatus.

Background technology

The Freshwater resources limited amount in the whole world, distributes inhomogeneous again, adds that the hurried growth of population and industrial or agricultural water consumption constantly increase, and the phenomenon of many regional lacks of water is still very serious.Although tellurian water is renewable and continuous circulation, because environmental pollution is on the rise, water quality goes from bad to worse.Global water resources crisis has brought great harm to the mankind.Reuse water is an effective way that solves at present insufficient water sources, and the middle water of reuse water refers to that sewage, after suitably processing, reaches certain water-quality guideline, meets certain service requirements, the water that can reuse.Compare with sea water desaltination, interbasin water transfer, reuse water has obvious advantage.From economic angle, the cost of reuse water is minimum, and from the angle of environmental protection, reuse of wastewater contributes to improve the ecological environment, and realizes the benign cycle of Ecology.

With regard to world wide, there is significant change in the management objectives for water resources, from controlling water, develop water, utilizing water to change " Recycling of water " and " reparation of Ecology and recovery " that is regenerated as core with water quality into, fundamentally realize the benign cycle of Ecology, ensure the sustainable use of water resources.Current sewage has been back to industry, agricultural irrigation and aquaculture through regeneration, the aspects such as municipal administration greening, life washing, groundwater recharge and the supplementary surface water.The water-deficient area of the U.S. is as California, Texas etc., its sewage reuse techuique development also early, to some urban sewage recycling of the U.S. in 1975 in the industrial aspect water yield, just accounted for 31% of total sewage quantity, only in California, just had more than reusing sewage engineering reaches 200 covers.

In China, the fact of water resources critical shortage causes the exploited space of ground water and underground water more and more less, even causes the havoc of ecotope, however the disparities between supply and demand of water resources be not still eased, and have the trend growing in intensity.Meanwhile, the quantity discharged of sewage is also sharply increasing, unprocessed or process below standard sewage to be directly thrown into water body still more common, is also constantly polluting environment.Recycling sewage generated by making technology, has been subject to governments at all levels and has paid attention to.In recent ten years city domestic sewage and Of Recycling Architectural Intermediate Water have been carried out to numerous research and practice work.Advance advanced treatment of wastewater, universal reclaimed wastewater reuse is the mankind and the Important Action that naturally develops, creates good water surrounding, promotion recycling-city development process in harmony.

Although compare with tap water, the extent of supply of middle water is little, at lavatory flushing, treegarden irrigation, road cleaning, carwash, city fountain, cooling apparatus, supplements the aspects such as water, and middle water is that best tap water substitutes water source.
