Description
Technical field
The present invention relates to a kind of non-crystalline silica inorganic agent and using the inorganic agent treated sewage technique and equipment,
Belong to environmental protection Processes and apparatus technical field.
Background technology
With the continuous improvement of people's living standards, and urban construction paces quickening, sanitary sewage and industrial wastewater
Processing, it has also become the most important thing of environmental protection timely and effective cannot such as be handled, and will seriously threaten the living environment of the mankind.
Sewage water treatment method in the prior art mainly has following two kinds：
One, chemical flocculation
This method is preferable to the removal effect of heavy metal, phosphorus, coloration, but to the removal effect of ammonia nitrogen and organic matter then compared with
Difference, and secondary pollution can be caused because of a large amount of sludge of generation.
Two, bioanalysis
Bioanalysis has a good removal effect to organic pollution and ammonia nitrogen, phosphorus, but to heavy metal, SS, coloration and it is toxic,
The removal effect of harmful substance is poor, and especially when concentration and temperature change, treated, and water outlet is unable to stably reaching standard, together
When need that the dehydration of sludge could be completed using a large amount of chemical floc, this necessarily makes dewatered sludge not only contain all
Pollutant more contains toxic, harmful chemical floc, equally causes serious secondary pollution.
Therefore, it to enable water outlet to recycle, realizes sewage recycling, reaches zero-emission, and solve secondary pollution
Problem, it is necessary to develop new sewage-treating agent and adaptable processing equipment and processing method.
