A kind of SBR methods batch (-type) sewage-treatment plant and its sewage water treatment method
Technical field
The invention belongs to field of sewage treatment, and in particular to a kind of SBR methods batch (-type) sewage-treatment plant and its dirt
Method for treating water.
Background technology
Water pollution refers to that the pollutant for being discharged into water body quantitatively exceedes background concentration and water body of the material in water body
Environmental carrying capacity, so as to cause the physical property of water body, chemical property and biological property to change, make the life of water body inherently
State system and function of water body are destroyed.
In recent years, relevant department of China has made many work in terms of water resource protection, still, due to the system of various conditions
About, national pollution of waterhead is in still development trend, has more than 90% urban waters seriously polluted, nearly 50% key cities source water
Matter does not meet the water standard of drinking water source.As can be seen here, although many works have been done in terms of water prevention and cure of pollution by China in recent years
Make, but the water quality of many rivers and lakes is still gradually being deteriorated.In this case, it is natively very in short supply in China's freshwater resources
On the premise of, it is completely more and more impossible without using the water source of fresh water being contaminated.That is, China waterworks is had to
It is faced with the water source for using the undesirable micro-polluted water of more water quality as Drinking Water.
At present, wastewater treatment in China faces three most distinct issues:1)Fund is serious not;2)Sewage disposal level is low;
3)The operating mechanism of sewage disposal is unreasonable.
