Embodiment 1

[0038] An anaerobic reactor for the treatment of high-concentration organic wastewater, comprising: a tank body 1, a sludge tower 2, a three-phase separator 3, a gas-liquid separator 4, an outlet weir 5, an outlet water distributor 6, and a heat storage device 7. External circulation pump 8, gas-liquid mixer 9, reflux collector 10, internal circulation pump 11, water inlet pipe 12, water outlet pipe 13, biogas pipe 14, liquid rising pipe 23, downcomer pipe 24, external circulation pipe 25, The hot liquid outlet pipe 26, the air inlet pipe 27, the internal circulation pipe 32 and the sludge discharge outlet 33; the tank body 1 is composed of: the irrigation top 15, the cylinder body 16 and the tank bottom 17; the sludge tower 2 is a tower structure, and the tower body 18 1. The water inlet distributor 19 and the outer circulation distributor 20 are composed; the three-phase separator 3 is composed of a separation screen 21 and an air collection chamber 22; it is characterized in...

Embodiment 2

[0056] The difference between embodiment 2 and embodiment 1 of an anaerobic reactor for the treatment of high-concentration organic wastewater is:

[0057] The upper part of the tower body 18 on the sludge tower 2 is a conical structure, and its apex angle is 120-165 degrees.

[0058] The setting of the conical apex angle at the top of the sludge tower 2 is to improve the mixing effect of water and air and to discharge water and air evenly into the tank, which is beneficial to the mixing of water and mud.

[0059] work process

[0060] An anaerobic reactor for the treatment of high-concentration organic wastewater. After injecting high-concentration organic wastewater mixed with microorganisms into the inner cavity of the tank body 1 through the sludge tower 2, the organic waste in the sewage is degraded by microorganisms. Pollutants are removed and biogas is generated, and then through the separation of gas, liquid and solid by the three-phase separator 3, the degraded sewag...

Abstract

An anaerobic reactor for treating high-concentration organic wastewater is based on basic principles of an up-flow anaerobic sludge bed reactor, gas stripping desulfurization and deamination and the like, and achieves SRT and HRT separation through a three-phase separator to obtain a high sludge concentration; and sludge and water are in full contact through disturbance of a large amount of biogasand internal and external circulating water flow of a tower type rotational flow water distribution structure, so rapid granulation of the sludge is achieved. The anaerobic reactor has the advantagesof improvement of the suspended matter resistance, the load impact resistance, the salt resistance and the toxicity resistance, reduction of the granular sludge inoculation cost, shortening of the sludge acclimation period, good mass and heat transfer effect, high volume load reaching 5-30 kg COD/m<3>, stability and reliability in running, high treatment efficiency, investment saving, large height-diameter ratio reaching 3-6, and low capital construction investment cost, and occupies a smaller area than a UASB anaerobic reactor. The biogas is utilized, so that the self-heating balance of thesystem is realized, the medium-temperature (35-38 DEG C) environment in a tank is ensured, and the running cost is low.
