Title Biological purifier for water to be treated, biological purifying system, and method of biological purifying
Abstract A biological purifier using biomass sources which are unused is provided, which can sufficiently remove heavy metal ions from a water to be treated containing the heavy metal ions and sulfate ions over a long period of time, and can sufficiently suppress the organics pollution of the treated water.The purifier of the invention is characterized in containing a rice shell having sulfate reducing bacteria.In addition, a biological purifying system of the invention includes: a treatment container which contains the purifier and maintains anaerobic condition; a supplying system which supplies the water to be treated to the treatment container; and a discharging system which discharges the treated water, in which the heavy metal ions are removed in the treatment container by the purifier, from the treatment container.
Scope of claims [claim1]
1. Kinds were processed the water the biological scavenger, the above biological scavenger is used, from including heavy metal ion and sulphuric acid ion was processed in the water to take the sulfide to remove the above heavy metal ion, its characteristic lies in: Includes to hold the sulphuric acid return to original state fungus grain shell.
[claim2]
2. According to claim 1, item of institute stated it to be processed the water the biological scavenger, above grain shell rice dregs yeast under anaerobic condition.
[claim3]
3. According to claim 1, item or the 2nd item of institute stated it to be processed the water the biological scavenger, above grain shell for rice hull or buckwheat shell.
[claim4]
4. 1 kinds were processed the water the biological purification system, the above biological purification system is used, from including heavy metal ion and sulphuric acid ion was processed in the water the above heavy metal ion elimination, its characteristic lies in includes: Processes the vessel, accepts according to claim 1, item to state the biological scavenger to the 3rd item of any item of institute, and is maintaining the anaerobic condition; The supply system, above was processed the water supplies to this processing vessel in; As well as the drainage system, will remove the above heavy metal ion processing water to discharge because of the above biological scavenger from the above processing vessel in the above processing vessel.
[claim5]
5. According to claim 4, item of institute stated it to be processed the water the biological purification system, above was processed the water constitution to be possible to act according to its gravity but moved according to the above supply system, the above processing vessel and above drainage system's order.
[claim6]
6. 1 kinds were processed the water the biological purification method, the above biological purification method is used, from including heavy metal ion and sulphuric acid ion was processed in the water the above heavy metal ion elimination, its characteristic lies in: Because of causing according to claim 1, item stated the biological scavenger with above to be processed the water to contact under the anaerobic condition to the 3rd item of any item of institute, but caused the above heavy metal ion to take the sulfide to precipitate, from above was processed in the water to remove.
[claim7]
7. According to claim 6, item of institute stated it to be processed the water the biological purification method, above was processed Shui Weikuang the Shankeng waste water.
