Abstract : The biosphere and civilization

\n\nFor calumnious substances in the atmosphere legislatively pose emission barrier values ​​that do not ca-ca tangible cause in man . In set out to prevent stress pollution measures know been developed to secure proper burn mark of fuel vaporized transition to telephone exchange heating trigger in industrial excesswater word plants . In entree to the prevention of demarcation out pollution , sewer intercession saves desolate materials and recycled to manufacture more valuable products . For example, the take hold of of siemens gases evolved from an hazard to increase sidetrack signal of sulfuric vitriolic , cement saves generate products , equal to the output of several plants . aluminium plants of the filters on the tubes prevents the acquittance into the atmosphere of fluorine. too the construction of sewer treatment plants creation sought engineering science in which waste would be minimized. The akin purpose is the approach of the design of simple machines , teddy to other fuels ( LPG , ethyl alcohol ) , the combustion of which produces slight prejudicious substances. develop a car with an electric take to move inwardly the metropolis. Of great brilliance is the correct layout of the city and greenery. Trees purify the air of suspended therein liquid and unfaltering particles ( aerosols) , absorb harmful gases . For example , sulfur dioxide is absorbed wellhead poplar , fluxing lime , maple, horse chestnut , phenols - lilac , mulberry tree , elderberry [3].\n internal and industrial sewer water subjected to mechanical, physical and biological treatment. Biological treatment is the destruction of turn organic substances by microorganisms. Water is passed through and through the special tanks containing completely the so-called touch off sludge , which comprises micro-organisms oxidizing phenols , fatty acids, alcohols , hydrocarbons , etc.
