The processing mechanism of sewage biochemical treatment equipment of the present invention:
A. complete anaerobism formula
This sewage biochemical treatment equipment is divided into three phases with organism degradation process under anaerobic:
(1) hydrolysis stage: mainly be by in the granule sludge and grow in the catalysis that microorganism on the combined stuffing is discharged into the extracellular enzyme in the waste water, with dissolubility larger molecular organics in the waste water and insoluble hydrolysis of organic matter is small organic molecule, resolved into cellobiose and glucose as Mierocrystalline cellulose by cellulase, starch is broken down into maltose and glucose, protein is broken down into small peptide and amino acid, and these small molecules after the decomposition can enter into the decomposition of carrying out next step in the body of cell by cell walls.
(2) souring stage: the small organic molecule that hydrolysis generates enters into and changes into more simple compound in the cell paste and be assigned to the extracellular, finally produces the volatile acid of short chain, as acetate etc.
(3) produce methane phase: in this stage, acetate, hydrogen, carbonic acid, formic acid and methyl alcohol all are converted to methane, carbonic acid gas and new cellular material.
In addition, also have the interception filteration in biological adsorption, combined stuffing district, little throwing out, swash plate (pipe) is to the centrifugation of mud, water, gas.
B. anaerobism, the oxygen of holding concurrently, aerobic multi-stage type
By regulating, this sewage biochemical treatment equipment forms anaerobic zone in the bottom, be discharged into the catalysis of the extracellular enzyme in the waste water by the microorganism in the granule sludge, with dissolubility larger molecular organics in the waste water and insoluble hydrolysis of organic matter is small organic molecule, the small organic molecule that hydrolysis generates enters into and changes into more simple compound in the cell paste and be assigned to the extracellular, produces the acidication effect of the volatile acid of short chain.Then enter aerobic zone, by oxygenolysis and the further degradation of contaminant of biological flocculation that is grown in the aerobic microbiological on the combined stuffing, simultaneously the biological sludge that produces is tackled, guarantee the sludge concentration of bottom, because the adding of medicament has promoted biological flocculation, and produce little throwing out, improve sludge settling efficient greatly, separate, guarantee effluent quality by swash plate (or inclined tube).Owing in whole process, formed anaerobism, double oxygen, aerobic multi-stage type, so can remove N and P simultaneously.
The principle of work of sewage biochemical treatment equipment of the present invention:
Sewage is entered by water inlet pipe 20, behind water distributor 8 uniform water distributions through the perforation formula, the granule sludge zone of flowing through earlier, sewage and mud thorough mixing also carry out biochemical reaction, after through combined stuffing 5, utilize growth microbial film thereon that sewage is carried out further bio-oxidation, biological flocculation, and utilize the crown_interception of filler, big granule sludge or suspended substance are trapped and sink, guarantee the sludge concentration of bottom.Because 4 adding medicine FeCl of doser
3Effect, on the one hand to promoting bio-oxidation and adsorption, can produce little throwing out on the other hand, separate through swash plate (or inclined tube) 3 then, gas after the separation is discharged by gas collection hole 1, and water picks out water pipe 16 by header 2 and effluxes, and wherein a part is used for refluxing, mud slips into the bottom through swash plate (or inclined tube) 3, and the entire treatment process is finished.
The backflow water yield is by reverse flow valve 18 and outlet valve 15 controls.The required oxygen of microorganism is carried by inlet pipe 9 by air compressor machine, is discharged by micro-hole aerator 7 and goes out, and air capacity is by 10 controls of the intake valve on it.Institute's adding medicine is carried by chemical feed pipe by doser 4, is added by doser 4 again.Excess sludge is discharged by mud valve 12 controls by the shore pipe 11 of bottom.Sewage biochemical treatment equipment of the present invention both can be handled sanitary sewage, can handle trade effluent again.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
