The common structure of anaerobic reactor comprises main body, in main body, be divided into main reaction region, bottom and Liang Ge region, gas-solid-liquid disengaging zone, top, in main body, be provided with the water inlet pipe and the shore pipe that stretch into body bottom, pond, in main reaction region, be provided with whipping appts, top is provided with triphase separator, settling region and rising pipe in gas-solid-liquid disengaging zone, the periphery of triphase separator is settling region, in settling region, be provided with filler, the top of settling region is provided with overflow weir, rising pipe is connected with overflow weir, is connected with firedamp drainage pipe on triphase separator.
But existing anaerobic reactor exists common problem to be, inner sludge concentration is lower, and anaerobion growing environment is bad, mass transfer effect is poor, and the speed of anaerobic treatment and efficiency are all lower, and effluent quality is unstable, processing efficiency is difficult to further raising, needs power stirring etc.
Summary of the invention
The deficiency that the utility model exists for existing anaerobism sewage disposal technology, the sewage anaerobic treatment device that provides a kind of running cost is low, treatment effect stable, processing efficiency is high tangential water inlet to stir voluntarily.
The sewage anaerobic treatment device that tangential water inlet of the present utility model is stirred voluntarily, by the following technical solutions:
This anaerobic processing device, comprise main body, in main body, be divided into successively from bottom to top main reaction region, three-phase separation area and sedimentation and filtration district, in three-phase separation area, be provided with Gas-solid-liquid separater, the bottom of main body is provided with liquid-inlet pipe and mud valve, sedimentation and filtration is provided with filler in district, and the top in sedimentation and filtration district is provided with rising pipe; Main body is cylindrical, liquid-inlet pipe is arranged on cylinder-shaped body tangential, the top of main reaction region is provided with washpipe, on washpipe, be distributed with shower nozzle and be provided with connecting joint in centre, the bottom of connecting joint and main body is connected with hollow rotating shaft, on the wall of hollow rotating shaft, be processed with hydro-peening hole, on hollow rotating shaft, be distributed with blade.
When above-mentioned reactor operation, start with floc sludge, sewage tangentially enters along main body, mixed solution in main body is produced to stirring action, promote again blades turning, the blade of rotation can stir again mixed solution more simultaneously, mixed solution in main reaction region is fully mixed, mass transfer is violent and efficiency is high, has promoted microorganism to contact and transmission ofenergy with the effective of pollutent, makes the abundant absorption degradation of microorganism and organic pollutant.Triphase separator is discharged for sludge settling, mud-water separation and collection and confinement of gases, the filler-reinforced precipitation of muddy water in sedimentation and filtration district, and the clear liquid after precipitation is discharged main body through rising pipe.Open mud valve and can regularly remove unnecessary mud.By the hydro-peening hole processing on the shower nozzle that distributes on washpipe and hollow rotating shaft, blade is cleaned.
The utility model water distribution is simple, without power, has realized the abundant stirring to mixed solution in main body, mud mixes with water fully, without dead angle, without precipitation, mix, mass transfer is violent and efficiency is high, makes the abundant absorption degradation of microorganism and organic pollutant, and treatment effect is stable, processing efficiency is high, improved effluent quality, reduced operational management difficulty, biogas yield is large.
