High Concentrated Organic Wastewater Treatment Process Using Bio-maker

摘要

The present invention relates to a manure that flows into a manure treatment plant and a treatment method for treating a high concentration of poorly decomposed livestock wastewater discharged from a livestock farm. The waste water treatment method of the present invention comprises: a. Equalizing the concentration and flow rate of the discharged high-concentration manure or livestock wastewater by using equalization; b. (C) adding a coagulant to the equalized wastewater in the step (a) to adjust the organic substance concentration and the nitrogen concentration to a desired level; c. An ammonia stripping step of selectively removing only the ammonia nitrogen without changing the concentration of the organic substance in the solid-liquid separated material in step (b), d. The degradable organic material in the object treated in the step (c) is decomposed using an anaerobic microorganism to make it easy for the subsequent aerobic microorganism to ingest, and the sludge returned from step (i) is fermented to produce an organic acid An anaerobic fermentation step, e. An ammonus step of reacting nitric oxide NO ₂ -N contained in anaerobically fermented sludge after returning from step (i) to step (d) and ammonia contained in wastewater to generate nitrogen gas, f. A microbial activation step of activating solidified soil microorganisms present in the biofond, g. The soil microorganism activated in the step (f) is supplied into the denitrification-inducing aeration tank and the aerobic microorganisms in the denitrification-inducing aeration tank together with the microorganism are used to treat the organic substance in the object to be treated in the step (e) A denitrification-inducing aeration step in which ammonia nitrogen is decomposed and nitrified with NO ₃ -N, followed by denitration through mixing, h. A denitrification step of reducing nitric oxide in the object to be treated in step (g) to nitrogen by using endogenous respiration of the microorganism in an oxygen-free state without the addition of an external carbon source, i. (d) solid-liquid separation of the microorganism from the object to be treated which is substantially oxidized and denitrified and obtained from step (h), and returning a part of the precipitated sludge to the anaerobic fermentation step (d); j. And coagulating the residual material from the supernatant liquid separated and precipitated in the step (i) and discharging it to the final treated water.
