Description

Novel biological anaerobic reactor of integration

Technical Field

The utility model relates to a waste water treatment technical field, more specifically say, relate to a novel biological anaerobic reactor of integration.

Background

In recent years, the anaerobic sewage treatment process has been developed rapidly, and various new processes and new methods are continuously appeared, including anaerobic contact method, upflow anaerobic sludge bed, baffle type anaerobic method, anaerobic biological filter, anaerobic expanded bed and fluidized bed, and third generation anaerobic process EGSB and IC anaerobic reactor, these reactors are generally used for treating waste water with good biodegradability, such as corn starch waste water, citric acid waste water, beer waste water, potato processing waste water, alcohol waste water, etc., and the treatment effect is remarkable, but the effect of treating high concentration waste water with poor biodegradability in fine chemical engineering, pesticide, pharmacy, etc. is not ideal, so that the anaerobic reactor only plays the role of hydrolysis reaction when treating such industrial waste water, and cannot play the real anaerobic effect, thereby leading to the increase of aerobic burden and increasing the operation treatment cost;

anaerobic reactors applied at present are developed based on UASB (upflow anaerobic sludge blanket), are improved by adopting different ascending flow rates and different methane stirring technologies, and have the following structural principle: wastewater enters a reactor from the bottom of a tank, flows upwards through a sludge bed consisting of flocculent or granular sludge, generates methane (mainly methane and carbon dioxide) along with anaerobic reaction when the wastewater is contacted with the sludge, causes the disturbance of the sludge bed, enters a settling zone through mixed liquid obtained after gas separation in a reaction zone for solid-liquid separation, the clarified treated water is discharged from a water outlet channel, settled microorganism solids, namely anaerobic sludge, are settled by gravity and return to the reaction zone, and the methane collected by a gas collection chamber is discharged out of the reactor through a methane pipe;

the good contact of the sludge and the organic matters is mainly realized by the stirring of water inflow and gas production, therefore, the most effective method for strengthening the mass transfer process of the conventional anaerobic reactor is to improve the surface hydraulic load and the surface gas production load, but the severe stirring generated by high load can lead the sludge in the UASB reactor to be in a complete expansion state, lead the reactor originally having SRT (solid retention time) > HRT (hydraulic retention time) to be converted to the SRT ﹦ HRT direction, lead the excessive loss of the sludge, in order to avoid the excessive hydraulic load and gas production load, the UASB reactor usually controls the rising flow rate of the inflow water within 1-2 m/h, and controls the height of the reactor below 6m, therefore, the UASB reactor has the defect that the mass transfer problem cannot be solved, which is an important reason that the operation effect of the UASB reactor is lower than that of an IC reactor and a UBF reactor, and the IC reactor can not only intercept the sludge, but also can strengthen the mass transfer process and realize the separation of high load and sludge loss, but the IC reactor has low volume load, does not meet the biodegradation time and can not be applied to the reason of industrial wastewater treatment, and because of the limitation of the conditions, a great part of industrial wastewater can not be treated by a conventional anaerobic reactor.
