Supplementary notes can realize multi-element ecology equilibrium principle of the present invention and engineering long term maintenance regulation effect principle below.
The multi-element ecology equilibrium principle:
1, the organic contamination principle is decomposed in the YL agent
A, YL agent are inoculated in immobilization on the carrier, and water body is dropped in on-the-spot flexibility domestication back, and rapid subsidence is in substrate, and are adsorbed on bulkhead wall, suspended substance, artificial pasture and water, the waterplant.Because the extracellular microbial exoenzyme, it is in the contact interface secure adhesion, difficult drop-off, and in the environment that is fit to own growth, set up the nest of oneself, rapid fissiparity.
B, YL agent have suppressed the growth of spoilage organism simultaneously with the organic substance in the form water of decomposition of metabolism and thoroughly degraded altogether (producing gas, water and inorganic salt) with the form of dominant group, and drive the improvement of overlying water water quality.
C, macromolecular organic pollutant can't directly be absorbed as nutrition source by mikrobe, need under the effect of the extracellular enzyme of microorganism secretion, be decomposed into small organic molecule, could be absorbed in the body by mikrobe; Under the intravital intracellular enzyme effect of mikrobe, small organic molecule is metabolised to water, gas and inorganic salt, excretes, and reaches the purpose of degraded organic contamination.
2, denitrogenation dephosphorizing
Denitrogenation dephosphorizing mainly passes through two aspects, and the one, through action of microorganisms, be nitrogen etc. with nitrogen transformation, discharge water body; The 2nd, make up the approach that nutrition is exported through ecosystem plant, take N, P out of water body.
The a action of microorganisms
The YL agent is set up detritus food chain in bed mud after throwing in like engineering section bed mud, reverse the corruption reaction in the original bed mud.And the black smelly immanent cause in generation river course, upwards water body release pollutent that corrupt just reaction brings and odorous gas ammonia, H
2S etc., simultaneously strong in activity, under the effect of the YL agent that efficient is high, to greatest extent nitric nitrogen is converted into nitrogen, take water body out of.
B nutrition output pathway makes up
Degraded through endogenous in bacteria agent, artificial pasture and water, the reinforcement engineering section pollutes improves the impact of extraneous contamination to the engineering section in conjunction with microbial film grid and row's mouthful Biological Pretreatment device.After above two parts's engineering measure is implemented, on the basis of water correction, get involved waterplant and animal, make up the biologic chain and the food chain of water body, make water body self-energy material cycle, and take N, P out of water body through the harvesting of waterplant.
2, engineering long term maintenance regulation effect principle:
The a microbial population:
The growth of the microbial population of bottom, river course inoculation or extinction are that the amount according to organic pollutant in bed mud and the water body decides; After improvement; Each item pollution concentration reduces; Microbial numbers will be withered away to a certain extent, reaches certain microbial biomass at last and can decompose amount of contamination and the balance that gets into pollution of river quantity; And after external strong pollution gets into water body, microbial numbers can increase along with organic increase again (after superpower pollution gets into, the river course is caused crushing ballistic, black smelly etc. like river course moment, need carry out microbial inoculum mend throw in).Simply, be exactly that mikrobe has how much eat nutrition, the mikrobe of how many respective numbers is just arranged, be a dynamic multi-element ecology balance.
The b extraneous contamination:
Guaranteeing the engineering section after enforcement, do not have great destructive pollution to impact, is to ensure the long-acting stable key of engineering achievement.
Keeping of the c ecosystem:
Through artificial maintenance, keep the good growth of waterplant, hydrocoles in the water body, ensure the normal operation of microbial film grid, row's mouthful Biological Pretreatment device, be to keep the long-acting stable important factor of water body.
