Potential sources of CO2 gas are (a) CO2 gas originating from municipal wastes within unlined landfill sites, (b) CO2 gas due to the oxidation of organic materials leaked from old latrines in the area, and (c) HCO3-from sulfate reduction of organic materials in the aquifer. [15] · CH2O+O2↔ CO2+H2O (3) · 2CH2O +SO42- ↔ H2S+2HCO3- (4) The concentration of NO3 in water sample varied from 55 to 67.5mg l-1 as shown in the Table 4.
The leachate is generally a strongly reducing liquid formed under Methanogenic conditions and on coming into contact with aquifer materials has the ability to reduce sorbet heavy metals in the aquifer matrix.

Main steam temperature at the export of superheater is the highest working temperature in boiler steaming-water channel,To approach the overheating materials allowed uppertemperaturelimit, The high temperature of main steam superheater damage easily caused, at the same time also can cause excessive expansion of steam turbine, thus in the production process should be timely regulates desuperheating water flow in order to maintain the main steam temperature constant[4].
According to the principle of water balance, secondary to the valve action by the following formula: Y=1-KX Y--- Secondary to the valve of the valve position X--- Desuperheated valve of the valve position Material layer differential pressure control system.
