Embodiment 1: fine molecular over-saturation dissolved oxygen
Fine molecular over-saturation oxygen-dissolving apparatus is to utilize physical action, make the large water clusters associating disperse to become independently individual molecule, increased the voidage between water molecules, simultaneously by after same oxygen molecule refinement, be added in the space between water molecules, make that oxygen is super-saturated to be dissolved in the water.Sewage is after this device refinement, activity, vigor and the activation capacity of material in water, G&W are improved, increase contact area, gas, solid, liquid intimate mixing and mass transfer velocity are improved, change substance reaction environment, improve interface free energy and concentration diffusion transmitting thrust, thereby effectively improved the dissolving power of various materials in water, for microbial growth and breeding provide adapt circumstance.
Water body also can reach following effect after fine molecular:
More than the concentration of oxygen in water can reach 50mg/L, tap water oxygen content can only reach 4-6mg/L, so water body oxygen concn after fine molecular is processed significantly improves, becomes over-saturation dissolved oxygen water.Water body after fine molecular over-saturation dissolved oxygen is after 1 year, the concentration of measuring residue oxygen is original more than 60%, the utilization ratio of oxygen can reach more than 95%, and conventional aeration is difficult to accomplish, as: the utilization ratio of boring aeration dissolved oxygen only can reach 5%～10%, and micro-pore aeration dissolved oxygen utilization ratio also only can reach 20%～40% left and right.This device can by oxygen over-saturation be dissolved in water, to water body create a sufficient aerobic environment, aerobic microbiological amount reproduction is conducive to the removal of various pollutents in water, is conducive to improve the ecotope of water body.
The effect of oxygen in water may be summarized as follows:
(1) the aerobic katabolism of organism
Aerobic katabolism refers under the participation of aerobic microbiological and aerobic-anaerobic microbe (heterotroph bacterium) in water, under the condition of dissolved oxygen abundance, the organism in water (representing with COD) is decomposed into CO
2and H
2o, and the metabolic process giving off energy.
(2) ammonification of organonitrogen and the nitrification of ammonia nitrogen
The in the situation that of dissolved oxygen abundance, organonitrogen ammonifying bacteria under effect, there is " aminating reaction " and be decomposed and be converted into ammonia-state nitrogen; There is again " nitration reaction " and be converted into nitrous acid nitrogen, nitrate nitrogen in ammonia-state nitrogen, then by anti-nitration reaction, nitrate nitrogen, nitrous acid nitrogen are reduced into gaseous nitrogen discharge water body under the effect of nitrifier, thereby reach the object of denitrogenation.
(3) biological phosphate-eliminating
In waste water, the form of common phosphorus is phosphoric acid salt (H
2pO
4 -, HPO
4 2-, PO
4 3-), poly-phosphate and organophosphorus.In general waste water, the phosphorus of 90% left and right exists with phos-phate forms.
PolyP bacteria absorbs the low fatty acids such as acetic acid and synthesizes a kind of salt (PHB) in cell under anaerobic state, and the decomposition of needed energy derive poly-phosphorus in thalline, has so also just caused phosphatic release.In aerobic zone, polyP bacteria is take free oxygen as electron acceptor(EA), by aerobic the PHB storing in body decomposition, and utilize and decompose the energy producing, phosphoric acid salt in excessive picked-up water body is converted into poly-phosphorus, like this in cell, aerobic phosphorous accumulating amount is greater than anaerobic phosphorus release amount, just can realize by precipitating action the object of biological phosphate-eliminating.
In a word, to the super-saturated oxygen that dissolves in the water body of eutrophication, under the acting in conjunction of above-mentioned several effects, will progressively recover the balance of nature of water body, improve the self-purification capacity of water body.

(3) ultrastrong magnetic field, in the mode of cutting magnetic line in mobile water body, makes the cell walls attenuation of algae in water, causes enchylema to run off, and causes the death of algae, thereby has reached the function except algae;
(4) sewage magnetization has very strong selecting bacteria effect, and directly sterilization rate can reach 70%～80%, but can not make all microbial deaths, especially functional microorganism, and the meeting surviving improves water body self-purification ability;
(5) mobile water forms electric current after being magnetized in water, and the existence of electric current makes the oxygen in water become active oxygen;
(6) magnetization can promote high aquatic organism growth, is conducive to ecosystem restoration, improves water body self-purification ability.

In the situation that containing compared with high-solubility oxygen, be conducive to the Fe in water
2+be oxidized to Fe
3+, Fe
3+be combined with phosphoric acid salt and form the tertiary iron phosphate of indissoluble and be deposited in the middle of bed mud, the soluble phosphate in water is reduced.And Fe
3+under neutrallty condition or alkaline condition, the free state phosphorus of the ferric hydroxide colloid of generation in also can planar water, forms large flco and is deposited to the bottom.Aluminum ion (Al
3+) etc. other metal ions also have above-mentioned coagulative precipitation effect.
B. microorganism dephosphorization
The in the situation that of dissolved oxygen abundance, polyP bacteria huge uptake phosphorus, is stored in phosphorus in thalline with the form of polymerization, thereby reaches the object that phosphorus is removed from water.
(3) hydrobiont is for the removal of nitrogen, phosphorus
Because fine molecular and magnetization can promote high hydrobiological growth, increase the activity of fish body endoenzyme, thereby can increase the removal of hydrobiont for nitrogen, phosphorus.
