Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment 1:
A kind of not Nitrogen-and Phosphorus-containing comprehensive wastewater back-end processing system, as shown in Figure 1, including wastewater treatment component and Treatment of Sludge Component.
Wherein, wastewater treatment component includes the first intermediate pool, the second intermediate pool, front end Fenton that waste water successively passes through Reaction, biochemical reaction treatment process, rear end Fenton's reaction, end filtration process and discharge pond, first intermediate pool and Between second intermediate pool be equipped with evaporator, between front end Fenton's reaction and biochemical reaction treatment process be equipped with level-one coagulating basin, Two-stage coagulation pond and third intermediate pool, are equipped with secondary settling tank between biochemical reaction treatment process and rear end Fenton's reaction, rear end is fragrant Pause and is successively arranged three-level coagulating sedimentation and the 4th intermediate pool between reaction and end filtration process;
Front end Fenton's reaction includes the first conditioning tank set gradually, front end Fenton's reaction pond and the second conditioning tank, rear end Fenton's reaction includes the third conditioning tank set gradually, rear end Fenton's reaction pond and the 4th conditioning tank, specifically, the first conditioning tank It is acid conditioning tank with the third conditioning tank, the second conditioning tank and the 4th conditioning tank are alkaline conditioning tank.
In wastewater treatment component, biochemical reaction treatment process includes the hydrolysis acidification pool successively carried out, anaerobic pond and aerobic Pond
And Treatment of Sludge component includes sludge concentration tank and filter press, sludge concentration tank is collected in the wastewater treatment component Sludge, and return line is equipped between sludge concentration tank, filter press and the second intermediate pool, so the supernatant of sludge concentration tank Liquid, the moisture in filter press can be back to the beginning step in wastewater treatment stage, and realization is traced back back processing.
Specifically, level-one coagulating basin, two-stage coagulation pond, hydrolysis acidification pool, anaerobic pond, aerobic tank, secondary settling tank and three-level are mixed The sludge party that solidifying Chi Junyu sludge concentration tank sludge pipeline connection, i.e. these stages generate by the filters pressing of Treatment of Sludge component at Mud cake discharge.
End filtration process is as the further safeguard before wastewater treatment discharge, including sand coarse aggregate ratio system and carbon filtration system System, also, discharge pond and be equipped with counter-flushing pipeline and sand coarse aggregate ratio system, carbon filtration system connectivity, meanwhile, end filtration process, discharge Return line also is provided between pond and the second intermediate pool.
It is further illustrated in conjunction with its treatment mechanism:
The comprehensive wastewater of Nitrogen-and Phosphorus-containing does not judge its TDS and COD, TDS≤9000mg/L after pretreatment, COD≤10000mg/L enters the second intermediate pool, if TDS >=9000mg/L, COD >=10000mg/L after pretreatment Into the first intermediate pool.
Liquid passes through evaporator evaporation process in first intermediate pool, and evaporation condensate enters the second intermediate pool, evaporation The outer processing of crystallized product committee.
Subsequent second intermediate pool to the first conditioning tank, adjusts pH between 2.5-3.0, with laggard by water pump lifting Enter front end Fenton's reaction pond, is added after Fenton reagent through the organic matter and coloration in Fenton oxidation decomposing wasting liquid.
After after the second conditioning tank adjusts pH to 8-8.5, into level-one coagulative precipitation tank, after PAC, PAM is added, precipitating Sludge enters sludge concentration tank, and supernatant enters two-stage coagulation sedimentation basin, and after PAC, PAM is added, it is dense that precipitating sludge enters sludge Contracting pond, supernatant enter third intermediate pool, and third intermediate pool is equipped with acid/base chemicals dosing plant, adjust pH and are used as into biochemical The front-end processing of reaction treatment process.
It is worth noting that, heating device is set in third intermediate pool with guarantee aftertreatment systems coolant-temperature gage 35 ± 2 degree or so, biochemical treatment section uses hydrolysis acidification pool+anaerobic pond+aerobic tank.
Hydrolysis acidification pond water temperature is at 35 ± 2 degree or so, and to guarantee effectively hydrolyzing acidification reactor, temperature is lower in winter In the case where can also be run with good state.
Hydrolysis acidification technique has been widely used in organic industry liquid waste processing and effect is very good, in order to guarantee hydrolysis acid Change pond treatment effeciency, spy controls waste liquid temperature before waste liquid is entered hydrolysis acidification.
Anaerobic waste water biological treatment refers under conditions of free-dioxygen through anaerobe (including facultative microbe) Effect, by waste water it is various complexity organic matter decomposition and inversions at the substances such as methane and carbon dioxide process.
During anaerobic bio-treated, complicated organic compound is decomposed, and is converted into simple, stable chemical combination Object releases energy simultaneously.
Wherein, most energy occurs in the form of methane, this is a kind of fuel gas, recoverable.
Only a small amount of organic matter is converted and synthesizes new part of the cell simultaneously, therefore for opposite aerobic method, anaerobism Method sludge growth rate is much smaller.
Aerobic biological treatment be using aerobic microbiological (including aerobic-anaerobic microbe) under the conditions of having existing for oxygen into Row biological metabolism stablizes it, innoxious processing method with degradation of organic substances.
Microorganism is that substrate carries out aerobic metabolism using organic pollutant present in water, by a series of biochemical anti- It answers, releases energy step by step, finally settled out with the inorganic matter of low energy position, reach innoxious requirement, so as to return to the nature ring Border is further processed.
Subsequent aerobic tank water outlet enters secondary settling tank, and sedimentation in secondary sedimentation tank sludge enters sludge concentration tank, second pond supernatant into Enter third conditioning tank and adjust pH between 2.5-3.0, then passes through Fenton oxygen after Fenton reagent is added in rear end Fenton's reaction pond Change the organic matter and coloration in decomposing wasting liquid, later again after the 4th conditioning tank adjusts pH to 8-8.5, into three-level coagulating sedimentation PAC, PAM are added in pond, further waste water is handled, guarantees that it meets discharge mark.
Precipitating sludge enters sludge concentration tank, and supernatant enters the 4th intermediate pool.
Waste liquid in 4th intermediate pool can pass through end filtration process before discharge, as last one before its discharge It ensures, specifically, Sand Filtration System removes various suspended matters, microorganism and other subparticles in water removal using filter medium, most Achieve the purpose that reduction water turbidity, purify water effect eventually.
Carbon filters the surface concentration that system forms a layer equilibration with activated carbon granule surface, then organic substance impurity absorption is arrived In active carbon particle, SS and organic matter tiny in waste liquid are removed.
Carbon filtration system water outlet enter discharge pond, discharge water quality of pond detect it is up to standard, then be discharged into waste water pipe network entrance Subsequent municipal sewage plant is discharged into environment after continuing, if discharge pond is detected not up to standard, is then discharged into the second intermediate water Pond continues with rear discharge up to standard.
Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill The people of art can understand the content of the utility model and implement accordingly, not limit the protection scope of the present invention. It is all according to the spirit of the present invention substantially equivalent transformation that is done or modification, should all cover the protection scope of the utility model it It is interior.
