Mud reaction zone, gas-liquid-solid three-phase separator (including settling zone) and gas chamber composition.There are following skills for anaerobic jar currently on the market
Art problem：1. water distribution has dead angle, anaerobic fermentation uneven, there is short flow phenomenon in Sludge Bed, influence processing capacity；Inside 2. not
Not reasonable equipped with interior return-flow system or interior return-flow system, reaction zone forms anaerobic grain sludge, mainly floc sludge
When, the water inlet volumetric loading of reactor cannot be very high, and the excessive floc sludge of flow upflow velocity is easy to be lost in, same influence processing
Ability.
Invention content
The purpose of this utility model, which is that, overcomes above-mentioned deficiency, provides a kind of modified form anaerobic jar.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme：
A kind of modified form anaerobic jar, including cylindrical tank, tank body be from bottom to top provided with water distributor, sludge reaction area,
Three phase separator, water outlet, gas outlet, the water distributor is in the form of annular discs to match with tank base, if being provided on water distributor
Transverse drainage unit is done, is evenly arranged with several discharge outlet on transverse drainage unit, transverse drainage unit includes spaced
Sewage drainage unit and recirculated water drainage cell, water distributor are provided with sewage inlet and circulation water inlet by tank body outside,
It is connected with sewage inlet after each sewage drainage unit parallel connection, after each recirculated water drainage cell parallel connection and recirculated water water inlet phase
Connection；Recirculated water intake is provided with below water outlet, recirculated water intake passes through circulating line, cycle suction pump and recirculated water
Water inlet is connected；Sewage inlet is also connected by T-type three-way reversing spherical valve with circulating line.
Further, the tank body is double layers of tank body, is vacuum layer inside double layers of tank body, it is ensured that fermentation temperature is not easy by outer
Boundary influences.
Further, it is equipped with helical form circulating line in the middle part of the circulating line, helical form circulating line is provided with heat preservation
Device.
Further, the attemperator is electric heater or condenser, it is ensured that the winter in cold or hot summer,
The temperature of the tank body fermentation temperature best with anaerobic bacteria activity is consistent.
Compared with prior art, the water distribution of the utility model is without dead angle, and effectively reducing in Sludge Bed has short flow phenomenon, i.e.,
Make the short flow phenomenon of generation, on the one hand can increase or reduce the inflow of water distributor by T-type three-way reversing spherical valve, eliminate short stream
Phenomenon；Another aspect recirculated water can individually enter water distributor or enter water distributor after being mixed with sewage inlet, increase dirty
Water water inlet volumetric loading, floc sludge not easily run off, and increase the processing capacity of anaerobic jar；Water outlet COD is reduced simultaneously.This reality
It is had the beneficial effect that with novel：Interior reflux is increased, short flow phenomenon is reduced, increases influent load, reduce water outlet COD, increase
The processing capacity of anaerobic jar is added.
