Abstract
A two-stage aerobic biological process for treating sewage includes such equipment as homogenizing pool, contact-oxidizing pool, aerating pool, deposition pool, mud-acidifying pool and water output and monitoring pool. The biochemical or chemical sewage with COD of 400-6000 mg/L can be treated. The BOD load for contact-oxidizing pool is 1-5 KgBOD5/cu.m.d. The organic substance load of aerating pool is 0.1-0.4 KgBOD5/cu.m.d. Its advantages are high load power, high impact-resistance, wide application range, and no residual mud.
Description
The invention belongs to a kind of sewage water treatment method.
Two sections aerobic methods handle sanitary sewage and wastewater from chemical industry organic loading height, handle advantage such as degree of depth height.The technical process of the method that Chinese patent CN1123770A proposes is made up of biological selector, one section aeration tank, one section settling tank, two sections aeration tanks, two sections settling tanks, this method is handled petrochemical wastewater and has been obtained successful result, influent density can reach 5000mg/L, and the organic loading of one section aeration tank can reach 5kgCOD/m
3.d, the water outlet COD of two sections aeration tanks can reach below the 100mg/L.This patent is handled petrochemical wastewater and has been obtained result preferably, but exists the bigger problem of surplus sludge volume.
The object of the present invention is to provide a kind of two sections new aerobic treatment processes, improve the suitability of two sections aerobic process, reduce the quantity discharged of excess sludge.
The present invention is applicable to the processing of sanitary sewage and chemical engineering sewage, and former water COD subject range is 400～6000mg/L, and the organic loading of contact-oxidation pool is 1.0～5.0kgBOD
5/ m
3.d, the organic loading of aeration tank is 0.1～0.4kgBOD
5/ m
3.d.Water outlet COD is less than 100mg/L.
Generalized theory, technical process of the present invention mainly comprises: homogeneous pond, contact-oxidation pool, aeration tank, mudpan, mud acidification pool and water outlet monitoring pond.At first through entering contact-oxidation pool after the homogeneous pond homogeneous adjustment, the water outlet of contact-oxidation pool enters the aeration tank to former water, and the water outlet of aeration tank is directly discharged; The mud part of settling tank is back to the aeration tank, and another part is discharged to acidification pool, is discharged to the homogeneous pond after acidifying is decomposed.
Accompanying drawing 1 has been described technical process of the present invention.
1 homogeneous pond;
2 contact-oxidation pools;
3 aeration tanks;
4 mudpans;
5 mud acidification pools;
6 water outlets monitoring pond;
The former waterline of a;
The b discharge line;

Be described with reference to the accompanying drawings technological process of the present invention.
Raw water at first enter in the homogeneous pond 1 mix, homogeneous, homogeneous is provided with stirring in the pond Facility can adopt churned mechanically mode, the mode that also can adopt air blast to stir, the homogeneous pond The time of staying can be controlled according to different processing objects. The water outlet of homogeneous pond enters catalytic oxidation Pond 2. Filler is housed in the contact-oxidation pool, and biology biofilm on filler forms biomembrane. Because Biomass in the contact-oxidation pool is bigger, and the ability of removing the COD load is stronger, and has stronger Adaptive capacity reaches stronger resistance to impact, can accept the waste water of variety classes and variable concentrations. Inlet COD concentration wider range of contact-oxidation pool is generally 400～6000mg/L, and is best Be 1000～5000mg/L; Biological load in the contact-oxidation pool can be controlled in 1.0～5.0kgBOD5/m
3.d the biomembrane that part comes off in the water outlet of contact-oxidation pool and the pond together enters Aeration tank 3. The aeration tank can operate under low organic loading, is generally 0.1～0.4 KgBOD5/m
3.d, mainly remove remaining organic matter, make the waste water after the processing can qualified discharge. The water outlet of aeration tank enters into mudpan, and mud turns back in the aeration tank, and excess sludge advances Enter to turn back to the homogeneous pond after the acidification pool acidifying is decomposed and former water is together processed. Going out of sedimentation basin Water enters the monitoring pond, and the water outlet in monitoring pond is if reach requirement and can directly discharge, as does not reach and want Ask and to turn back to the homogeneous pond. The operating temperature of contact-oxidation pool and aeration tank is 15～40 ℃, pH Value is 6～9. The operating temperature of acidification pool is 30～50 ℃, and the pH value is 5～8.
The present invention can process food, fermentation, sanitary sewage, and the petrochemical industry factory effluent, and the organic loading of contact-oxidation pool can reach 1.0～5.0kgBOD5/m
3.d, the organic loading of aeration tank is 0.1～0.4kgBOD5/m
3.d, but the influent density process range is 400～6000mg/L, The COD of water can reach below the 100mg/L after processing. The present invention does not have excess sludge and produces. This Invention is compared with other technology of processing similar water, have flow process simple, process organic loading The characteristics such as height, processing degree of depth height, no excess sludge.
