Abstract
The invention relates to a new method for acclimating active sludge resisting high chloride ion wastewater. Through domestication culture, the active sludge can stably grow in sewage containing chloride ions at the concentration of 20g/L, and can degrade pollutants in the water. A shooting-and-bouncing-ray (SBR) method is adopted in a reaction process, and only one intermittent reaction tank is arranged; and compared with a continuous active sludge method, the new method has the advantages hat: a secondary sedimentation tank and sludge returning equipment are not required to be specially arranged, and capital investment can be saved compared with that of a common active sludge method. The new method also has the advantages of large reaction kinetics, high efficiency, flexible running mode, good denitrification effect and readily available materials. The acclimated sludge is common municipal sludge, readily available and low in price, and the new method is suitable for acclimating sludge in sewage treatment plants of coastal cities and oil fields. The new method effectively overcomes the influence of a high chloride ion adverse factor, and successfully realizes biological treatment of the high chloride ion wastewater.
Description
Technical field
The present invention relates to a kind of novel method of acclimating active sludge resisting high chloride ion wastewater.
Background technology
Development along with coastal industry and sea transport industry, the water that the seawater of take is main carriers pollutes day by day serious, traditional method adopts physico-chemical processes to process this first kinds of pollution matter, but owing to having and easily causing secondary pollution after Applied Physics chemical Treatment, more scholar's choice for use biological process is processed ocean sewage in recent years.Owing to also having a large amount of CL---in seawater
-, CL
-microorganism is had to very strong toxic action, because the salt of high density can cause microorganism cells osmotic pressure to change fast, cause somatic cells to break or bacteria growing inhibiting, biological treatment system is damaged, therefore in actual at present sewage treatment project, sludge acclimatization cultivation and processing to high-salt wastewater are also more difficult, do not have mature experience to use for reference.
At present to the domestication of processing high chlorine sewage active sludge municipal sludge is domesticated for to master by improving step by step the method for chlorine ion concentration, also have some scholars research directly ocean mud to be tamed, all obtained certain effect.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of salt tolerant activated sludge acclimatization method of uniqueness, present method is that municipal sludge is tamed, but it is different from traditional acclimation that municipal sludge is improved step by step to salt concn.After domestication finishes, the removal of organism, ammonia nitrogen HeTNDeng contamination index is all reached to (GB18918-2002) middle one-level A standard of country's " urban wastewater treatment firm pollutant emission standard ".
Specific embodiments:
The object of the invention is to be achieved through the following technical solutions:
L technical scheme is to carry out in SBR technique, and process cycle is controlled at 24-72h, and the whole cycle comprises into processes such as water, aeration, the stirring that stops exposing to the sun, static, drainings; Aerobic stage DO is controlled at that 2-3mg/L, PH are controlled between 6-8, test water is simulation ocean sewage, and CL-concentration 20g/L, adds C, N, P.
L domestication test is that common municipal sludge is tamed, and gets the vexed Bao Santian of active sludge of lane one concentration, after Jing Chenpaishui, directly in mud, adds the CL configuring
-concentration is at the simulated seawater of 20g/L, and after each end cycle, draining 50%.After the domestication in several cycles, make sludge concentration stable, COD, ammonia nitrogen removal frank are in 90% left and right, and TN removes in 60% left and right, salt tolerant sludge acclimatization success.
L adopts and increases by a small margin cooling method change temperature condition, realizes the best of carbon, nitrogen organic in high chloride ion sewage is removed.6 ~ 25 ℃ of optimum treatmenting temperatures
The present invention is owing to taking above technical scheme, and it has the following advantages:
1. the domestication time is short, adopt the more traditional chlorine ion concentration of the raising step by step method acclimation sludge of this acclimation method more to have superiority on the time, the seawater of traditional method acclimation sludge adaptation chlorine ion concentration 20g/L is needs 60-70d probably, and this experimental technique just can be tamed out the active sludge that adaptation chlorine ion concentration is 20g/L seawater in 40-50d.
2. draw materials conveniently, the acclimation sludge that present method is used is common municipal sludge, draws materials conveniently, and low price, adapts to coastal cities and disposing polluted water in oil factory and start acclimation sludge.
embodiment
Utilize the device shown in accompanying drawing 1, by controller, control reactor intermittent water inflow, in single SBR process pool, good
Oxygen stage D O is controlled at that 2-3mg/L, PH are controlled between 6-8, test water is simulation ocean sewage, CL
-concentration 20g/L, adds C, N, P concentration.Get the vexed Bao Santian of active sludge, after Jing Chenpaishui, directly in mud, add the CL configuring
-concentration is at the simulated seawater of 20g/L, and after each end cycle, draining 50%.After the domestication in several cycles, make sludge concentration stable, COD, ammonia nitrogen removal frank are in 90% left and right, and TN removes in 60% left and right, salt tolerant sludge acclimatization success.Adopt and increase by a small margin cooling method change temperature condition, realize the best of carbon, nitrogen organic in high chloride ion sewage is removed.6 ~ 25 ℃ of optimum treatmenting temperatures.
