Embodiment Construction

[0028] refer to figure 1 , the unit schematic diagram of the organic wastewater and sludge treatment system of the present invention. like figure 1 As shown, the organic wastewater and sludge treatment system 100 of the present invention comprises an aerobic tank 11, an aerobic tank 13, and a mud-water separation tank 15, and the aerobic tank 11 receives an organic wastewater 21 and a photosynthetic bacteria liquid 23, wherein the organic The waste water 21 can be pre-stored in a stock solution tank, or directly input from an external pipeline. The organic waste water 21 is produced by industrial factories, food factories, domestic waste water, or landfills. The photosynthetic bacteria solution 23 is added to the aerobic tank 13 every day at 1 / 800 to 1 / 200 of the volume of the aerobic tank, preferably 1 / 600 to 1 / 450, to the aerobic tank 13 . The concentration of bacterial strain in photosynthetic bacteria liquid 23 is every milliliter 10 8 to 10 11 Colony forming unit (CFU...

Abstract

An organic wastewater and sludge treatment system consists of an oxygen bath, an aerobic tank, and a sludge separation tank. The oxygen bath receives an organic wastewater and a photosynthetic fluid; the photosynthetic fluid is added to the oxygen bath at a rate of 1 / 800 to 1 / 200 of the oxygen bath volume per day, and the concentration in the photosynthetic fluid is 108 to 1011 CFU / mL; the photosynthetic fluid will process the organic wastewater into the first biological sludge; the aerobic tank to receive the first biological sludge and a spore bacteria liquid; the spore bacteria liquid is added into the aerobic tank at a ratio of 1 / 300 to 1 / 800 of aerobic tank volume, and the concentration of spore bacteria liquid is 108 to 1011CFU / mL, thus processing the first biological sludge into a second biological sludge. The sludge separation tank receives the second biological sludge and separates the moisture in the second biological sludge from the suspended solids, thus obtaining the effluent and a biological sludge and discharging same.

Description

technical field [0001] The invention relates to the field of organic waste treatment, in particular to the treatment of organic waste water and sludge by using microorganisms. Background technique [0002] With the rise of the concept of environment and ecological conservation, manufacturers are paying more and more attention to the treatment of waste liquid. In the treatment of waste liquid, organic waste liquid and inorganic waste liquid are generally classified and treated. For organic waste liquid, it can be processed into a slurry state through concentration and chelation. In addition, it is found that bacteria, fungi and other microorganisms can rely on organic matter in organic waste liquid as a carbon source, and organic nutritional microorganisms will grow and reproduce in large numbers. Through The proliferation, fermentation and photosynthesis of microorganisms such as bacteria and fungi can decompose organic matter and form so-called biological sludge, also know...
