Abstract
The treating process for waste water containing organic matter has the technological scheme including regulating waste water pH value to 5-6 with alkali, regulating the temperature to 38-40 deg.c, and performing biological treatment in anaerobic biological filtering bed reactor at 35-38 deg.c. In the anaerobic biological filtering bed reactor, waste water inflowing from the lower water inlet is made to pass through sewage section, stuffing section, triphase separating section and clarifying section successively, methane is led out from the triphase separating section, and clear water is led out and back flowed from the overflow trough in the clarifying section. Inside the anaerobic biological filtering bed reactor, the anaerobic bacteria strains, including hydrolysis bacteria, acidifying bacteria, acetobacterian and methane bacterian are cultured. The present invention has simple treating process and high efficiency, and has treated waste water reaching the exhaust standard.
Description
One, technical field: the present invention relates to a kind of food-processing industry organic wastewater treatment process.
Two, background technology: administer organic waste both at home and abroad and adopt anaerobic biological treatment, this method energy consumption height is applicable to the waste water of lower concentration, once studies and the improvement method that adopts will be mixed slag burn processing method after wet oxidation process and evaporation are arranged for high-concentration waste water.Two kinds of big technical requirements height of method facility investment, energy consumption is also big, and is uneconomical.
Three, summary of the invention: purpose of the present invention is exactly at the deficiencies in the prior art, and a kind of organic wastewater treatment process is provided.Its technical scheme is: with alkali the pH value of waste water is adjusted to 5-6, temperature regulation is advanced anaerobe filter bed reactor then and is carried out a biological disposal upon to 38-40 ℃, and the reflection temperature is controlled at 35-38 ℃; Bio-filter bed reactor successively by mud section, packing section, three phase separation section and settling section, is drawn methane gas in the three phase separation section by following water-in water inlet upper reaches, draws clear water at the settling section overflow groove and refluxes.The anaerobe bacterial classification that carries out cultivating in the biological treatment process at anaerobe filter bed reactor comprises: hydrolysis bacterium, acidifying bacterium, acetic bacteria and methanobacteria.
Method treatment process of the present invention is simple, the waste water treatment efficiency height, and the waste water after the processing can reach emission request.
Four, description of drawings: do not have
Five, specific embodiment: with alkali the pH value of waste water is adjusted to 5-6, temperature regulation is advanced anaerobe filter bed reactor then and is carried out a biological disposal upon to 38-40 ℃, and the reflection temperature is controlled at 35-38 ℃; Bio-filter bed reactor successively by mud section, packing section, three phase separation section and settling section, is drawn methane gas in the three phase separation section by following water-in water inlet upper reaches, draws clear water at the settling section overflow groove and refluxes.The anaerobe bacterial classification that carries out cultivating in the biological treatment process at anaerobe filter bed reactor comprises: hydrolysis bacterium, acidifying bacterium, acetic bacteria and methanobacteria.Method treatment process of the present invention is simple, the waste water treatment efficiency height, and the waste water after the processing can reach emission request.
