Abstract
The utility model provides an internal recycle anaerobic reactor with an active adjustment function, belonging to the field of sewage treatment. In the initial stage of anaerobic debugging, an air storage tank stores a little methane generated by a system, and a methane recycle device leads the reactor to generate internal recycle, so that the sludge can be promoted to generate the expansion and fluidization status, and the debugging speed can be accelerated; in the case that the system stops charging water, the internal recycle of the reactor can be controlled and kept, and the status and the activity of the sludge can be kept; when the sewage is high in the content or the toxicity of the inorganic heavy ions such as the heavy metal, the calcium, the magnesium and the like, the heavy sludge of the inorganic heavy ions such as the heavy metal, the calcium, the magnesium and the like can be periodically discharged, the internal recycle quantity can be controlled and increased, and the impact can be reduced, so that the internal recycle anaerobic reactor is wide in application range; and the internal recycle anaerobic reactor has the advantages of being short in starting time, higher in the impact resistance of the inorganic heavy ions such as the heavy metal, the calcium, the magnesium and the like, and more stable in running.
Description
Technical field
The utility model is a kind of internal-circulation anaerobic reactor with active adjustment function, belongs to sewage treatment area.
Background technology
Internal recycle (IC-Internal Circulation) anaerobic reactor is made up of four parts such as mixing zone, first reaction chamber, second reaction chamber and internal circulation system.After sewage gets into reactor drum and phegma mixes; Gas in that the first reaction chamber anaerobic reaction produces is collected in the entering riser tube by the one-level triphase separator; Produce gas and propose effect, the gas-entrained mud mixture rises, and after the gas-liquid separator separates of reactor head, discharges; Remaining mud mixture then through the mixing zone of the downward inflow reactor of muddy water downtake bottom, forms internal recycle thus.Internal circulation system is the core system of IC; It has the lift velocity that strengthens first reaction chamber, increases the living weight of first reaction chamber, improves the COD volumetric loading greatly, makes mud be in the effect of expansion fluidized state, dilution water inlet Pollutant levels, backflow basicity, is foundation and the important assurance of IC as high efficiency anaerobic reactor.
The internal circulation apparatus of existing anaerobic reactor is to rely on the first reaction chamber normal reaction to produce the spontaneous internal recycle that biogas causes.Following shortcoming is arranged: 1) the system debug stage; Because of anerobes has just begun to cultivate, produce biogas seldom, internal recycle can not carried out; And internal recycle can not carried out and is made IC not possess mud to be in effects such as expansion fluidized state that so vicious cycle causes start time very long; 2) the IC reactor drum is intake when discontinuous, and the first reaction chamber biogas has produced, and internal recycle promptly stops, and mud can not be in the expansion fluidized state all the time, and sludge activity can reduce; 3) water inlet changes when big or toxic, and gas production rate can reduce, and causes the internal recycle effect to reduce, and internal recycle reduces and further causes the first reaction zone change of water quality big or toxicity is big, forms vicious cycle, continues to reduce treatment effect.4) inorganic heavy ion such as heavy metal, calcium magnesium is deposited on anaerobic device bottom and can not in time gets rid of in the sewage, causes heavy mud accumulation, influences the system handles effect.
Summary of the invention
To above-mentioned technical problem; The utility model provides a kind of internal-circulation anaerobic reactor that ACTIVE CONTROL is regulated the internal circulating load function that has; Change the traditional IC anaerobic reactor and generally can only pass through the spontaneous internal recycle of anaerobic methane production gas, can't carry out the shortcoming that ACTIVE CONTROL is regulated, had weak point start time; Inorganic heavy ion impact capacities such as preventing from heavy metal, calcium magnesium are stronger, move more stable advantage.
The utility model is realized through following technical scheme:
A kind of internal-circulation anaerobic reactor with active adjustment function; Form by reactor body, water inlet pipe, rising pipe, the bottom cone-plate of falling the umbrella shape, biogas recirculation unit; Have water inlet pipe to link to each other with rising pipe between reactor body and the biogas recirculation unit, the bottom cone-plate of falling the umbrella shape is arranged at biogas recirculation unit bottom; Reactor body by methane voltage-stabilizing cabinet, mixing zone, first reaction zone, return line, one-level triphase separator, second reaction zone, biogas-lift pipe, settling region, secondary triphase separator, go out the gentle liquid/gas separator of water channel and form; After sewage pressurizes through the reactor drum intake pump; Get into mixing zone and return line backflow sewage and mix back entering first reaction chamber; Through getting into second reaction zone behind the one-level triphase separator; Through getting into the water outlet of water outlet canal behind the secondary triphase separator, the biogas that one-level triphase separator secondary triphase separator is collected gets into the laggard methane voltage-stabilizing cabinet of gas-liquid separator through the biogas-lift pipe again, and biogas gets into the biogas storage tank stores; The biogas recirculation unit mainly comprises biogas storage tank, biogas under meter, biogas variable valve, water sprayer; Biogas storage tank stores biogas is used as the active internal recycle; Biogas under meter, biogas variable valve are used for regulating the biogas amount; Water sprayer produces negative pressure gets into reactor drum as biogas power by on the anaerobic reactor main body; The bottom cone-plate of falling the umbrella shape is positioned at reactor bottom, comprises many group cone-plates of falling the umbrella shape, shore pipe composition.
Described biogas variable valve is divided into manually and electronic two kinds.
The beneficial effect of the utility model is:
1, at the anaerobism debugging initial stage, gas-holder stores a small amount of biogas that system produces, and makes reactor drum produce internal recycle through the biogas recirculation unit, can impel mud to generate the expansion fluidized state, accelerates debugging speed;
2, stop under the situation of water in system, may command keeps the reactor drum internal recycle, keeps mud state and activity;
3,, can regularly the heavy mud of inorganic heavy ion such as heavy metal, calcium magnesium be put outward and control and strengthen the internal recycle amount when big for inorganic heavy ion content such as sewage heavy metal, calcium magnesium or toxicity, alleviate impact, wide accommodation;
4, have weak point start time, inorganic heavy ion impact capacities such as preventing from heavy metal, calcium magnesium are stronger, move more stable advantage.
