Phosphatic method.
Background technique
The elements such as phosphorus, nitrogen are exceeded in water, can accelerate the eutrophication of water body, and this phenomenon is more serious in China, give work
Industry, aquatic products industry, agricultural and tourist industry all bring great harm.The nutrient concentrations such as nitrogen, phosphorus increase, and are that algae is a large amount of
The reason of breeding, wherein again using phosphorus as key factor, while excessively high nitrate content can also cause human body and natural environment
Harm.The IV of the recreational water area of general industry Water District and human body non-direct contact is primarily adapted for use according to current national regulation
In the discharge standard of class water, total phosphorus content requires≤0.3 (lake, library 0.1), and total nitrogen content requires≤1.5, China's Drinking Water
Nitrate concentration should be less than 10mg/L when sanitary standard (GB5749-2006) regulation surface water makees water source, and underground water is as water source
When nitrate concentration should be less than 20mg/L.
Under current art, since sewage treatment tail water C/N ratio and concentration of nitrogen and phosphorus are relatively low, there are carbon sources for advanced nitrogen
Insufficient problem, if further realizing the synchronous dephosphorization of denitrogenation with more comparable technical difficulty.
Conventional synchronization denitrification dephosphorization technique is mainly bioanalysis, and outer adding medicine achievees the purpose that deep phosphorous removal.But tradition is raw
Sludge age is shorter when object method synchronous denitrification dephosphorizing, and phosphorus content is higher in sludge, it is therefore necessary to run under high loads, but denitrogenation
Require sludge age longer again in journey, nitrification can only just can be carried out in the long underload system of sludge age, therefore biological denitrificaion removes
There are certain contradictions in sludge sludge age for phosphorus, and this contradiction becomes apparent from when water temperature is lower.And medicament progress is added at the same time
When chemical dephosphorization certain influence can be generated to the growth of microorganism.It the use of excess sludge caused by bioanalysis is also that environment is protected
One big hidden danger of shield.
