Experimental Study Of Sewage Simulation Add Microbial Agents Of Subsurface Infiltration System Processing

The experiment developped a microorganism germ that aims at a special soil layer of the subsurface wastewater infiltration system, for enhancing decontamination processing ability of the system for living dirty water, the water burthen of the exaltation system carries to carry and pollution, shortenning system startup time. In the text to the emulation experiment research that increased the subsurface wastewater infiltration system processing of the microorganism germ a living dirty water to carry on series.Pass to check cultural heritage first, the source grown to the germ carries on quest, end selected by examinations the live and dirty mire of the town planning dirty water processing factory as to grow a source, increase a loose of the adsorbent and floppy reagent of certain comparison to prepare the microorganism germ, to the different germ the formulation carry on the germ stub to count, and carried on the parts of physiology bio-chemical experiment to the germ stub that separates.On this foundation, to increase certain quantity to assist to anticipate in the microorganism germ, sneak in to install special soil in the soil, pass certain special soil to go together with for instance a case to the measurement of the organic quality,pH,the germs number and the physiologies in the special soil, the germ quantity can attain in the special soil 1.0×10¹²E/g, the nitric turns the germ quantity > 1.4×10⁸ E/g, the anti- nitric turns the germ quantity > 1.4×10¹² E/g.End, design the subsurface wastewater infiltration system emulation experiment device, fill special soil to put into equip in, make selection a 4 cm/d, 6 cm/d, 8 cm/d, 10 cm/d four kinds of water power burden start experiment. The contrast increase with do not increase different water power burden,same water power of special soil,same fluid matter to carry different fluid matter to pass in and out the water fluid matter index sign, the analytical special soil is to startup time, COD, Ammonic Nitrogen, Total Nitrogen, Nitrate Nitrogen, Total Phosphorus that imitates underground system of infiltration .total phosphoric clean the influence produce.Pass an above experiment certificate, after increasing the microorganism germ, underground system of infiltration is cleaning organic matter,ammonia nitrogen,total phosphoric ability to strengthen obviously, the ability that clean total nitrogen,nitrate also has to certainly promote, and shortenned the start of the system to circulate time consumedly. The germ’s prepares to go in brief and easily, getting material convenience, use to go together with to anticipate price cheap be easy to acquire, and the conservancy of the germ without special request, be advantageous to that technical expansion.Suit to construct underground system of infiltration of living dirty water of increase the microorganism germ in SHEN YANG region, the underground infiltration system of this research establishment imitates to equip already basic attain the design request, can apply that technique in in try the underground infiltration of the scale the dirty water processing engineering.
