3 quality recovery processes
3.1 quality recovery phase I
Along with the amount of compound enzymic preparation with 6～10ppm (preferred 8ppm) splashed in the contaminated sewage continuously, its distinctive anti-oxidant, anti-microbial effect can improve useful microbic activity (katalysis) and reduce the activity (negative catalysis) of spoilage organism, assorted bacterium.Organism decomposer, nitrifier, sulfation bacterium, the denitrifier isoreactivity of aerobic zone are improved, promote organic decomposition fully, ammonia is to the transformation of nitrate ion, and hydrogen sulfide is to the transformation of sulfate ion.Thereby the turbidity of aerobic zone is reduced.In addition, " prozyme " can also make the organism decomposer of anaerobic zone, the activity of photosynthetic bacterium (green sulfur bacteria, red thiobacterium, red non-thiobacterium) improve, make the green sulfur bacteria of aerobic area, red thiobacterium begin to carry out light compositing, consume hydrogen sulfide; Make red non-thiobacterium also begin to carry out light compositing, decomposing organic matter.Promote the decomposition of settled sludge, the mud after being decomposed begins the floating water surface of going up.The required DO of useful microorganism that increases at aerobic zone, DO by repressed spoilage organism, assorted consumption that bacterium subtracts is replenished, but owing to along with the rolling up of aerobic useful microorganism, DO is consumed in large quantities, aerobic zone can temporarily shoal, and turbidity also increases thereupon.
This shows, owing to promoted the organic decomposition of aerobic zone and anaerobic zone, ammonia, hydrogen sulfide in the anaerobic zone generation, decomposed by nitrifier, sulfur oxidizing bacterium and double oxygen photosynthetic bacterium, be released to (stench alleviates) in the atmosphere after concentration reduces significantly, the methane that aerobic area produces directly is released in the atmosphere.Can also see the atomic little bubble that produces because of denitrogenation at the water surface.
Can't carry out in the photosynthetic facility, photosynthetic bacterium is substituted by sulfur oxidizing bacterium and utilizes organism to consume hydrogen sulfide.
3.2 quality recovery phase II
Still the dosage according to 6～10ppm (preferred 8ppm) adds compound enzymic preparation continuously, the useful microbic activity of living at aerobic zone and anaerobic zone further improves, and the active of spoilage organism, assorted bacterium further reduces, and impels organism to decompose fully, aerobic zone further enlarges, and turbidity reduces.Meanwhile, the photosynthetic bacterium of aerobic area comes to life, and the consumption of hydrogen sulfide increases, and promotes organic decomposition.At this moment, the ammonia that discharges in the atmosphere, the concentration of hydrogen sulfide reduce significantly, and foul smell disappears.The generation of methane still continues, and the small bubbles that produce because of deamination increase, and sedimentary mud further decomposes, and the floating water surface of going up of mud is arranged.The second half in this stage begins to occur blue-green algae at aerobic zone, produces oxygen under photosynthesis, and DO increases substantially.
3.3 quality recovery phase III
In order to have kept oxygen condition, also need in water, splash into compound enzymic preparation by the amount of 6～10ppm (preferred 8ppm).In this stage, useful microbic activity further improves, spoilage organism, assorted bacterium keep and are subjected to holddown, further promote cyanophycear growth, under photosynthesis, DO further improves, organism is decomposed by complete oxidation, turbidity reduces significantly, and settled sludge reduces significantly, and settled sludge is in the state of double oxygen, aerobic coexistence.The ammonia and the hydrogen sulfide that produce under the oxygen condition of holding concurrently through in the nitrifier of aerobic zone, the decomposition of sulfur oxidizing bacterium, are converted into nitrate ion and sulfate ion, and stink disappears.Along with the minimizing of settled sludge, the methane bubble also reduces thereupon, and final settled sludge is decomposed fully, and methane, ammonia, hydrogen sulfide also disappear thereupon, and the natural, ecological in waters is recovered, and aquatic organism is survived.
After polluted waters is purified fully, as continue to have sewage to enter continuously,, need to continue in water, to instil continuously compound enzymic preparation by the amount of 3ppm in order to have kept oxygen condition.
After purifying fully,, must press the amount continuous drip compound enzymic preparation of 8ppm in some facility, carrying out under the photosynthetic situation.
Beneficial effect of the present invention is: 1, prozyme is not a biological bacteria, does not have the risk ecological out of control of external bacterial classification; 2, fundamentally solve body eutrophication, and form running balance, reach the purpose of restoration of the ecosystem with the source of pollution that continue input; 3, realize the organic sludge biological decomposition, solved the problem of organic sludge harmless treatment effectively; 4, can reduce colibacillary quantity in the improvement waters effectively; 5, operation and simple to operate, the polluted waters that only needs to administer at need increases compound enzymic preparation storage and Dropping feeder, has debugged rate of addition and has got final product, and implements based technique for in-situ remediation; 6, the technology implementation comprehensive cost is low.Traditional relatively artificial desilting, plant ecological pasture and water, the summation cost that repeats to construct of engineering such as accent is low in artificial aeration, the outer water.
