[0044] A kind of sewage resource treatment process of bacteria-algae particle circulation treatment, sewage resource treatment process of bacteria-algae particle circulation treatment includes the following steps:
[0045] Step one, sewage treatment, sewage treatment is first by liquid feeding pipe group 18 to the anaerobic tank 4 is added to sewage, anaerobic treatment of sewage, using one of the liquid pump 14 to the decomposition tank 5 is transported, and decomposition tank 5 is bacteria-algae liquid, so using the cycle timing switch 909 can drive waterproof light belt 13 and electromagnetic valve 910 timing switch, in the opening effect of electromagnetic valve 910 and waterproof light belt 13, can provide the required carbon dioxide and light for bacteria-algae in decomposition tank 5, further to the organic matter, nitrogen, phosphorus pollutants in sewage are removed effect;

[0047] The working principle of the above embodiment is:
[0048] Before use, the liquid feeding pipe group 18 needs to be connected with the sewage conveying structure, to ensure the effect of anaerobic tank 4 sewage conveying, the liquid feeding pipe group 18 in the equipment is a number of pipeline combination conveying pipeline, it is existing mature technology, this application does not make too much superfluous words to existing mature technology, such as equipment dc power supply 10, liquid pump 14, magnetic stirrer 15 etc., and the water pump 604 in the equipment will be connected in advance with additional water pumping equipment, to ensure the effect of extraction of water on the top of precipitation assembly 6 after precipitation, and the precipitation assembly 6 will add flocculation agent when precipitating water, to ensure the precipitation layering effect of sewage after decomposition tank 5 is treated by photosynthesis, and the float block 603 arranged in the precipitation assembly 6 can ensure that the water pump 604 is always at the same distance below the liquid level under the gravity of lead block 605, to ensure the extraction effect of water after precipitation;
[0049] And the device in the anaerobic tank 4 in the sewage anaerobic treatment, the reaction gas, the gas contains carbon dioxide, methane, hydrogen sulfide, the gas will enter into the filter box 7, the gas first through the gas screen plate 802 on the iron oxide desulfurization treatment, which will produce ferrous sulfide and water, avoid the influence of hydrogen sulfide gas, then with methane and carbon dioxide gas will be separated under the polyimide gas separation membrane 804, the methane gas is blocked, and then the carbon dioxide will pass through the polyimide gas separation membrane 804 into the combination pipe structure, then through the check valve 902 into the telescopic cylinder 903, the check valve 902 in the second combination pipe 901 only allows gas into the telescopic cylinder 903, not allowed to export gas, so the treated carbon dioxide will be accumulated in the telescopic cylinder 903, and then will compress the damping spring 906 to make the gas in the telescopic cylinder 903 is under pressure, and the gas in the filter box 7 will also be different with the anaerobic accumulation, and then on the side of the polyimide gas separation membrane 804 will also produce higher pressure, at this time the air valve 807 will be opened due to the pressure value, and then the methane gas is discharged from the treatment box 1, and the air pipe 806 of the device is also connected with the gas collection device in advance, which will not cause the problem of gas overflow, and the pressure of the air valve 807 of the device is far greater than the pressure of the check valve 902, so it will not affect the effect of gas collection in the telescopic cylinder 903.
[0050] When the cycle timing switch 909 time reaches the opening condition, the waterproof lamp belt 13 and the electromagnetic valve 910 will be started, so that when the electromagnetic valve 910 is opened, the pressure gas in the telescopic cylinder 903 will enter the gas ring cavity 907 through the delivery elbow 904, and then be discharged to the decomposition tank 5 through the gas outlet 908, and at the same time the waterproof lamp belt 13 is opened, the instantaneous photosynthesis is carried out, and the electric field output of the conductive electrode 11 can decompose the tank 5 in an electric field, the weak electric field stimulates the metabolic activity of algae bacteria, strengthens the adsorption and flocculation effect, and achieves excellent denitrification and phosphorus removal effect, thereby increasing the treatment of sewage, and the device uses the output carbon dioxide and light source in the gap, and the consumption of carbon dioxide by photosynthesis is instantaneous, which ensures that the algae need carbon dioxide when there is light, and basically do not need carbon dioxide when there is no light, avoids the problem of huge waste caused by continuous supply of carbon dioxide in the dark period, and avoids the problem of too high pH caused by excessive consumption of carbon dioxide, or too low pH caused by too much carbon dioxide, so as to create a more stable growth environment for microorganisms and ensure the treatment effect of sewage.
[0051] After the decomposition tank 5 is decomposed, the treated sewage in the decomposition tank 5 is transported to the sedimentation assembly 6 through the liquid pump 14, and then the decomposition liquid is stratified by standing, the upper clear water is pumped out through the water pump 604, and the dirt at the bottom is discharged through the sewage elbow 602.
