Background technology
At present, cost performance highest sewage water treatment method, first elects biochemical treatment, and process is:1. it is multiple with the breeding of microorganism Make to be converted into organic matter (microorganism containing hydrocarbon nitrogen oxygen sulfur phosphorus and a small amount of inorganic salt etc. is labeled as A), 2. and/or with microorganism Metabolism clearing up, come out with form of heat, and/or release biogas (methane, nitrogen, carbon dioxide, sulfuration Hydrogen, volatile acid etc. are labeled as B), 3. and/or by microorganism adsorption (polysaccharide of microorganism secretion can optionally, by difficult degradation Adsorption of Organic simultaneously drops its low aqueous solubility, and separates with sewage, and water quality is purified (be labeled as C), and becomes biochemical sludge A part, cooperatively becomes biochemical sludge and is labeled as D with A, because absorption of the microorganism to Organic substance has certain limit, pin Different C values are had to different sewage operating modes.
Biochemical system needs certain activated sludge recoverable amount (mainly considering the amount of Biomass, i.e. A), and unnecessary part is (main consideration system normally runs the maximum bearing value of C to biochemical excess sludge, is labeled as DIt is remaining), it is necessary to biochemical system is discharged, no The harm of row or the biochemical excess sludge of few row is for well known to industry.
That is, the load (in terms of COD) that biochemical system is really removed only has part B, the life of general sanitary sewage Change system is all less, only preliminary sedimentation tank and Aerobic Pond, and the heat and biogas of generation is less, and surplus sludge volume accounts for total load (in terms of COD) more than 80%, chemical industry trade effluent, because of difficult degradation, though biochemical system is larger, the heat of generation and biogas Also less, biochemical surplus sludge volume accounts for total load (in terms of COD) 70% or so to yield;With natural animal and/or plant as raw material Industrial undertaking biochemical system, anaerobism produce heat and biogas amount it is larger, biochemical surplus sludge volume account for total load (with COD is counted) except 60% or so, but microbiological pharmacy (production of antibiotics enterprise), because of traditional antibiotic biochemical sewage system only Have aerobic, cause biochemical surplus sludge volume to account for total load (in terms of COD) more than 80%.
