Description
Technical Field
The utility model relates to the technical field of high-concentration wastewater treatment, in particular to a high-efficiency three-phase separator and an anaerobic sludge bed reactor.
Background
The livestock breeding wastewater is four high wastewater, the load concentration of the livestock breeding wastewater is 50-100 times of that of the domestic sewage, and the treatment is very difficult. For example, the pig raising wastewater, most of the soluble organic matters in the excrement and the soluble organic matters hydrolyzed from the excrement are dissolved into the sewage, the sewage contains a large amount of organic matters, the COD index of the sewage reaches 20000mg/l, and the BOD index reaches 10000 mg/l. The sewage contains all pig manure, and the concentration of ammonia nitrogen is as high as 1800 mg/l. And the excrement is dissolved and hydrolyzed after being soaked in water for a long time, so that the water and the excrement are completely mixed, and the concentration of suspended matters in the sewage reaches 18000 mg/l.
The concentration of the inflow suspended matters of the traditional anaerobic sludge bed reactor is 1500mg/l, and after the front-end pretreatment of the general aquaculture wastewater, the inflow suspended matters of the anaerobic reactor are 6000-7000 mg/l, which is far higher than the inflow requirement of the traditional anaerobic sludge bed reactor. If still adopt traditional design mode, mud adheres to on the triphase separator easily, leads to mud rate of recovery to descend, can cause the gas collection mouth to block up simultaneously, and the maintenance needs a large amount of manpower and materials.
USAB (upflow anaerobic sludge blanket reactor) is one of the fastest growing digesters, mainly sewage flowing from bottom to top flows through an expanded granular sludge blanket. The device mainly comprises three areas, namely a sludge bed, a sludge layer and a three-phase separator, wherein the separator divides gas and prevents solids from floating and rushing out, so that the MRT ratio is greatly increased compared with the HRT, the methane production efficiency is obviously improved, and the sludge bed area only accounts for 30% of the volume of the digester on average, but 80-90% of organic matters are degraded in the sludge bed area. The three-phase separator is key equipment of the UASB anaerobic digester, mainly has the functions of gas-liquid separation, solid-liquid separation and sludge backflow, and mainly comprises a gas seal, a settling zone and a backflow seam.
At present, the angle of the vertex angle of the three-phase separator in the prior art is set between 55 degrees and 60 degrees, the angle can enable sewage to collide with a baffle plate of the three-phase separator in the upflow process, gas-solid-liquid three phases are not kept in a stable phase-fused state due to collision, biogas is upwards collected through an outlet and then recycled due to different densities of the gas-solid-liquid, biogas slurry and sludge fall downwards due to high densities to complete separation of the gas-solid-liquid three phases, but part of the sludge can be adhered to the three-phase separator due to the self-adhesion and slip characteristics of the sludge, so that the recovery efficiency is reduced, and the outlet can be blocked. The existing three-phase separator has low mud collection efficiency, low methane separation and collection efficiency and easy blockage of a methane collection hole, so that the application of the three-phase separator in the field of high-suspended matter wastewater treatment is limited.
