The invention will now be described in detail with reference to the accompanying drawings principle and operational process across the biochemical sewage disposal system of the temperature difference:
Embodiment one
The application of sanitary sewage disposal:
The present invention is across the biochemical sewage disposal system of the temperature difference, and such as Fig. 1, shown in Fig. 3: sewage is entered by water inlet pipe 1 across temperature The biochemical sewage disposal system of difference, treated, and clear water is stored in clear water reserviors 10, when 10 liquid level of clear water reserviors is in high liquid level, is opened The water of clear water reserviors 10 is discharged dynamic clear water water outlet pump 19;
Sewage enters the conditioning tank 2 of the invention across the biochemical sewage disposal system of the temperature difference by water inlet pipe, by grid 29 Afterwards, by the stirring or aeration stirring of the blender in conditioning tank, sewage mixes with sewage original in conditioning tank and sludge, makes Water quality is uniform, is easy to the processing of subsequent anaerobism, mixed sewage is by the outlet pass between conditioning tank 2 and anaerobic device or overflows Weir is flowed, into anaerobic device, anaerobic device uses anaerobic digester, pass through the stirring of anaerobism blender 26 in anaerobic device, Mixed with the anaerobic sludge of anaerobic device with anaerobic bacteria flora, by the expansion of anaerobic bacteria flora it is numerous with metabolism, remove sewage in it is organic Object is minimized the COD value in sewage, and when temperature is at 15 DEG C or more, anaerobic effluent is entered aerobic by anaerobic effluent pipe 14 Pond 7, by the expansion of the aerobic flora in aerobic tank 7 it is numerous with metabolism, remove sewage in organic matter, obtain the COD value in sewage To reduce, by the processing of anaerobic and aerobic flora, the organic matter in water has largely been removed, and the water outlet of aerobic tank 7 is logical Crossing outputted aerobic water valve 15 makes mud-water separation by the filtering or precipitating of rear separator 16 into rear separator 16, and rear point Enter clear water reserviors 10 after standard water discharge from device 16, stores or pass through clear water water outlet pump after disinfection treatment in clear water reserviors 19 and clear water outlet pipe 18 be discharged;
At 15 DEG C or less, environment temperature and inflow temperature simultaneously decline temperature, and Biochemical Treatment is decreased obviously or nothing At this moment effect stops the aeration of aerobic tank 7, the water of aerobic tank 7 is discharged, and activated sludge is back to conditioning tank 2 by reflux pump With anaerobic device 3 or be discharged into the storage mud tank of sludge treating system, anaerobic effluent valve 39 and aerobic flowing water Valve 15 are closed, The preceding separation inlet valve of preceding separator 13 is opened, and anaerobic effluent enters preceding separator 13, sludge reflux after mud-water separation To anaerobic device, the sewage after separation enters the PH conditioning tank 5 of chemical oxidation device, in PH conditioning tank 5, passes through the first dosing The acid medicines such as hydrochloric acid or sulfuric acid are added in case 21, control the pH value of water between 3 to 5, water later enters dosing pond 4 or good Oxygen pond 7 adds ferrous sulfate and hydrogen peroxide in dosing pond 4 or aerobic tank 7 by the second dosing tank and third dosing tank, or Start hydrogen peroxide generator and generate hydrogen peroxide, the starting pond PH blender 58 is stirred, and starting dosing blender 36 carries out Stirring, starting aerobic tank blender 27 are stirred, and water is made to carry out Fenton's reaction in aerobic tank 7, and the water after Fenton's reaction passes through The inlet valve 41 that flocculates enters flocculation plant, and lye is added by the 4th dosing tank 24 in flocculation plant, adjusts the pH value of water To 8 to 9, flocculation aid is added by the 5th dosing tank 25, enters flocculation sedimentation tank, muddy water after stirring in flocculation stirring pond Water after separation enters rear separator 16 by overflow weir, be filtered or precipitate in rear separator 16 or UF membrane after Water enter clear water reserviors 10;
In the case where anaerobic device carries out heat treatment, temperature can also be carried out whithin a period of time for anaerobic device water outlet At this moment Aerobic Process for Treatment can be handled sewage using short aerobic plus chemical oxidation treatment technique, i.e., good using setting front and back Oxygen pond, when temperature is suitble to biochemical treatment, outputted aerobic water valve before opening, the water of aerobic tank is entered by preceding outputted aerobic water pipe before making Aerobic tank afterwards, preceding aerobic tank and rear aerobic tank carry out aerobic reaction simultaneously, outputted aerobic water valve before when low temperature closes, before opening point From inlet valve, water and sludge after emptying in aerobic tank, anaerobic device water outlet enter preceding aerobic tank 30, in preceding aerobic tank into Row aerobic reaction, the preceding water outlet of aerobic tank 30 enter the preceding separator 13 being arranged among the aerobic tank of front and back, enter chemistry later Oxidation unit carries out Fenton's reaction in rear aerobic tank 31, enters flocculation plant and rear separator 16 later, finally enters clear Pond 10 stores after disinfection treatment in clear water reserviors or is discharged by clear water water outlet pump 19 and clear water outlet pipe 18;
Temperature increases, when being suitble to biochemical treatment, the flocculation inlet valve 41 of separation inlet valve and flocculation plant before closing, Anaerobic effluent valve 39 or preceding outputted aerobic water valve 60 and aerobic flowing water Valve 15 are opened, outputted aerobic water passes through at rear separator Enter clear water reserviors, sludge reflux to aerobic tank 7 or preceding aerobic tank 30 and rear aerobic tank 31 after reason, starting aeration carries out anaerobism and adds Aerobic process processing.
