Technical field
The utility model relates to Dephosphorization reagent dosages in technical field of sewage more particularly to a kind of sewage treatment
Automatic regulating system.
Background technique
In recent years, domestic sewage treatment plant has generally carried out mentioning mark retrofit work, and Effluent criteria is generally by " cities and towns are dirty
Water treatment plant's pollutant emission standard " the level-one B standard in (GB18918-2002) is increased to level-one A standard, at part of contaminated water
Reason factory is even increased to higher class surface water III or IV class standard.It is the dephosphorization process of relatively economical using biological phosphate-eliminating, but
It is achieved by a variety of factors, and water outlet total phosphorus is difficult to stably reach the level-one A standard of 0.5mg/L, needless to say tighter class
Surface water III or IV class standard.
For this situation, present most domestic sewage treatment plants are general to the control of total phosphorus in mentioning mark transformation process
All over the method for being aided with chemical dephosphorization again using biological phosphate-eliminating, so that water outlet reaches the even more tight standard of level-one A.Chemistry removes
Phosphorus mainly has synchronous chemical dephosphorization (mainly to add in biochemical reaction tank tail end, but need to generally reserve Dephosphorization reagent throwing after secondary settling tank
Add some points, in case case of emergency under come into operation, it is ensured that final outflow water total phosphorus is up to standard) and rear chemical dephosphorization (mainly after secondary settling tank
Add individual coagulating sedimentation basin), what is generallyd use now during chemical dephosphorization is gone out according to sewage treatment plant
Water water quality, the unlatching quantity and open frequency of manual control chemical dephosphorization dosing pump, to control certain dosage.
Since municipal sewage plant haves the characteristics that water water, water quality are unstable, cause in sewage disposal process
The water outlet total phosphorus moment of biochemical reaction tank changes.Since sewage treatment plant's general technology process is longer, only according to water outlet data
Judge that the operation conditions of front-end processing facility has certain hysteresis quality, and be discharged data once it is exceeded show to have at this time surpass
Water discharge is marked, biggish environmental accident may be generated when serious.Therefore traditional according to water outlet total phosphorus data, operations staff
The shortcomings that Controlling operation method of manual operation adjusting dosage is that dosage is adjusted not in time, causes to be discharged total phosphorus concentration fluctuation
Greatly, it is not able to satisfy the needs of process stabilizing operation, Some Enterprises often take excessive add to achieve the purpose that stable water outlet
The measure of chemical dephosphorization medicament, but this virtually increases the dosage of medicament again, causes unnecessary waste, increases dirt
The operating cost of water process enterprise.
