Also connect by biogas pipe the boiler that promising thermostat(t)ed water solution reaction tank provides heat energy at the top of UASB anaerobic tower, described boiler is biogas and coal dual-purpose type boiler, is also provided with gas-holder and thionizer between boiler and UASB anaerobic tower simultaneously.
What the sludge treating system in the system of described industrial sewage and active sludge synchronous processing mainly utilized is thermal hydrolysis principle, make the part microorganism cells body expanded by heating in mud by heating and break, discharging protein, mineral substance and cell membrane fragments.Its target is the hydrolysis by organic solid in mud, the biodegradable performance of reinforcement sludge.After thermal hydrolysis process, a part of suspended solids hydrolysis in mud becomes easier biodegradable dissolved matter, improves the clearance of subsequent treatment process to volatile matter.
The treatment scheme of this treatment system is first the industrial sewage from plant area's sewage network is entered equalizing tank, then promoted by sewage pump and enter UASB anaerobic tower, sewage produces acid, aerogenesis through the effect of anaerobion in UASB anaerobic tower, greatly reduces organic concentration.The water outlet of UASB anaerobic tower enters anaerobic-aerobic treating pond, and water outlet enters vertical sedimentation basin and carries out mud-water separation, supernatant liquor qualified discharge, and mud major part enters constant temperature hydrolysis reaction bath by sludge pump and carries out thermal hydrolysis reaction, and small portion is disposed to sludge thickener.Wherein the initial sludge concentration of thermal hydrolysis reaction tank controls at 8.5-9.0g/L, and temperature of reaction controls at about 80 DEG C, and the reaction times controls 1 hour, can realize mud decrement more than 50% by above-mentioned process.The rear supernatant liquor of thermal hydrolysis reaction enters phosphorus recovery reaction tank and carries out phosphorus recovery reaction, and lower floor's sludge reflux, to UASB anaerobic tower, continues circular treatment.Phosphorus reclaims feeding lime in reaction tank, regulates about pH to 9.0, is under the condition of 120r/min, reacts 5 minutes at rotating speed, and generate alkali calcium phosphate precipitation, wherein supernatant liquor is back to equalizing tank.Phosphorous recovery can reach 92.8%.The microcosmic salt reclaimed can as the raw material of phosphorus industry, and phosphorus is Nonrenewable resources, therefore significant to the recovery of phosphorus.A large amount of biogas that UASB anaerobic tower produces as clean energy, can provide heat energy for thermal hydrolysis reacts through desulphurization reaction.This system is specially adapted to the organic waste water of high density.
The system of the industrial sewage that the utility model obtains and active sludge synchronous processing, its technique effect have following some:
1) mud decrement is obvious, and decrement can reach more than 50%;
2) system capacity recycle, the organism in sewage is become biogas by UASB anaerobic tower, and for system provides heat energy after burning, in constant temperature hydrolysis reaction bath, the reacted residual sludge reflux of thermal hydrolysis is to UASB anaerobic tower, for anaerobic reaction provides effective temperature;
3) to the effective recycling of phosphor resource, 92.8% is reached to phosphorous recovery;
4) system operation cost is low, and the sludge treatment expense of whole system is only 1/10 ~ 1/20 of common sludge treatment system.The biogas that thermal hydrolysis reaction operation main energy sources is produced by UASB anaerobic tower provides, and when aerogenesis deficiency, suitably provides heat energy with coal combustion.The microcosmic salt reclaimed, as valuable by product, also can produce many economic benefits.Mud decrement, then reduce expense greatly for follow-up sludge disposal simultaneously.
