Description
Technical field
The system and method for organic waste water is cultivated and handled to a kind of aerobic particle mud (AGS), belongs to environment protection and technical field of waste water processing.Specifically, be the system and method that short period SBR cultivates aerobic particle mud and processing organic waste water.
Background technology
The aerobic particle mud technology is the new technology that has the engineering application potential that twentieth century was developed since the nineties, is expected to be used to handle municipal wastewater, community life sewage, food industrial wastewater, milk preparation trade effluent, phenolic wastewater or other poisonous and harmful waste water etc.Therefore, the research and development of aerobic particle mud technology have become one of focus of domestic and international research and development.
It is one of prerequisite of this technical applicationization that the mass-producing of aerobic particle mud is cultivated with producing.Both at home and abroad the substrate cultivated round AGS of researchist and conditions such as organic loading, structure of reactor and operating method thereof, hydrodynamic shear and sedimentation time, seed sludge and dissolved oxygen are to the big quantity research of AGS cultivation having carried out.Continuous Flow BAS or AUS reactor and sbr reactor device all once were used to aerobic particle mud and cultivated, and were applicable to more that AGS cultivates but practice shows SBR because selectivity reaches flexible and convenient operation by force.
When utilizing SBR to cultivate AGS, SBR operational conditions such as cycle time and concrete arrangement thereof have a significant impact the performance characteristic of the AGS that cultivates win or lose and turn out.There are 4h, 6h, 8h, 12h and 24h etc. in the SBR system in the operational cycle commonly used.These operational cycles also once were used to the cultivation of AGS.But, also do not see the bibliographical information that the SBR operational cycle that is lower than 4h is applied to the AGS cultivation.
Because the granulating of aerobic sludge can improve the wherein metabolic activity of microorganism, thereby require to provide more organic substrates, promptly require higher organic loading.Therefore, successful AGS cultivates and all adopts higher organic loading in the document.The common method that improves organic loading is to strengthen the concentration of organic substrates in the culture system, and this requires to drop into more organic substrates and has increased the cultivation cost.And too high organic concentration causes the thread fungus excessive multiplication easily, and is unfavorable to the further granulating of mud, even can cause filamentous bulking and cause cultivating failure.
Suitably shorten the cycle time of SBR operation, can under the situation that does not increase organic concentration, improve the organic loading of culture system, help the granulating of aerobic sludge, reduce the cost that AGS cultivates.For SBR handled organic waste water, cycle time was short more, and the utilising efficiency of sbr reactor device is high more, and the SBR of same volume can handle more waste water, and perhaps handling the identical water yield only needs littler reactor.Therefore, short period SBR handles the characteristics that organic waste water has system availability height, construction investment province.
In addition, in the AGS culturing process, it is very complicated very delicate that the pH value of culture system changes.In the one-period, the pH value can consume basicity with ammonia nitrogen minimizing and biological nitration before this and reduce, and can produce basicity with denitrification subsequently and go up.Therefore, at the different time of one-period, the pH value of culture system is different.In the different steps of cultivating, the system pH Changing Pattern is also different.At the cultivation initial stage, the mud main body is a floc sludge in the system, and microbial metabolic activity is lower, and microorganism is relatively low to the uptake rate of carbon nitrogen phosphorus, thereby the pH value changing down at initial stage in cycle and amplitude are also just less.The sludge denitrification activity is also lower, and is less in later stage in cycle pH value rise speed and amplitude.Late stage of culture is then opposite, because the granulating of mud has improved the metabolic activity of microorganism, microorganism is faster to the uptake rate of carbon nitrogen phosphorus, and initial stage in cycle pH lowers speed and amplitude can be bigger; In addition, that mud granule has formed from outside to inside is aerobic, anoxic and anaerobic condition, and the microorganism denitrification activity also greatly strengthens, in later stage in cycle pH value rise speed and amplitude increasing.
The pH value can influence the disassociation of amphiprotic substances such as protein, and then influences surface property such as the surface charge of sludge microbe in the culture system and hydrophobicity, and the pH value is lower than 7 environment and can causes hyphomycetic quick breeding, the biophase of change mud.Therefore, the pH value produces very big influence to the granulating of aerobic sludge, the pH value of culture system is carried out appropriate regulation and control have great importance.
The present invention is exactly the System and method for that employing short period SBR cultivates aerobic particle mud and handles organic waste water, adds the pH value of relevant cultivation of supercarbonate regulation and control and system for handling.
Summary of the invention
The object of the present invention is to provide a kind of aerobic particle mud to cultivate and handle the system and method for organic waste water; fast, economical and mass-producing is stably cultivated and produce aerobic particle mud; and remove organism and nitrogen phosphorus substance in the organic waste water effectively, the through engineering approaches that promotes the aerobic particle mud technology is used.
The system and method for organic waste water is cultivated and handled to aerobic particle mud of the present invention, adopts short period SBR system to cultivate aerobic particle mud and processing organic waste water, and the supercarbonate regulation and control are cultivated and the pH value of system for handling to add.
Described sequencing batch reactor system is made up of main reactor 12, water inlet system, water exhaust system, aerating system and corresponding self-con-tained unit.Described main reactor 12 is a cylindrical reactor, and its aspect ratio is greater than 15, along 4 water port of height for reactor direction equidistant placement or thief hole.Described water inlet system is made up of water inlet 1, aqua storage tank 2, peristaltic pump 3 and self-con-tained unit 12; Water exhaust system is made up of drain solenoid valve 6 and self-con-tained unit 12; Aerating system is made up of air compressor 9, aerator 10 and self-con-tained unit 12; Described control device is micro computer time switch or PLC controller.
