1. the gap formed by the upper cone and the lower cone can enable water flow to flow out in a planar and oblique downward radiation mode at a high flow speed, so that a high turbulent flow hydraulic condition is formed, and mud and liquid are fully mixed and contacted.
2. When the backflow mud water passes through the annular gap between the lower cone and the bottom of the main reactor, the backflow mud water can obtain larger kinetic energy and carry sludge particles
The particles or the flocs run and impact the dead corner area at the bottom of the tank, so that the mixing of mud and water at the bottom of the tank is enhanced, and the service efficiency of the bottom container is ensured.
3. When the rising muddy water passes through the reflecting plate, larger turbulent flow can be formed to run along the direction opposite to the rising flow, so that the muddy water mixing in the area below the reflecting plate is further enhanced, the area is in a near-fluidized state, and the biochemical reaction efficiency is improved.
4. When the rising muddy water passes through the annular ring formed by the reflecting plate, the flow speed is changed, and the original flow is recovered after the flow speed is instantly increased
And the micro-disturbance is formed in the area between the reflecting plate and the three-phase separator, and the structure of a sludge suspension layer is not damaged, so that the sludge-water mass transfer reaction and the upper sludge-water separation are facilitated.
Because of the nearly fluidized hydraulic condition formed by the water inlet area at the bottom of the reactor, the reactor has stronger impact resistance, can adapt to different water quality load changes and certain anti-toxicity impact capacity, and simultaneously, the dead-angle-free siltation of the reactor improves the volume utilization efficiency of the reactor and the overall treatment efficiency. The reactor can adapt to organic wastewater in various industries and has better load impact resistance and toxicity resistance.
A non-blocking water distribution anaerobic reaction device and a method for treating wastewater by using the same mainly adopt the technical principle that: wastewater to be treated enters the reactor body from the upper cone body through the water inlet pump, flows through the bottom of the reactor in the oblique downward direction through a gap between the upper cone body and the lower cone body, and is well mixed with sludge. Meanwhile, muddy water on the upper part of the reactor (close to the lower part of the three-phase separator) is conveyed into the lower cone by the backflow pump through a muddy water collecting pipeline, and backflow water forms a large impact flow velocity through a gap between the lower cone and the bottom of the reactor, so that bottom activated sludge is greatly disturbed. The upper cone, the lower cone and the reflecting plate at the bottom of the reactor form a larger turbulent flow area together, so that sludge deposition caused by dead corners at the bottom is prevented. The middle upper part of the reactor can keep the sludge suspended and fully contacted with the wastewater under the action of ascending flow velocity, methane bubbles and micro turbulence, thereby effectively solving the problem of local siltation inside the reactor. And finally, the sludge and water flow through the three-phase separator to realize sludge and water separation, and part of sludge sinks to the periphery of the water collecting pipe and is sucked into the return pipe and then flows back to the lower cone at the bottom of the reactor. And the waste water after mud-water separation flows through the water outlet weir and finally enters the water outlet pipe to be discharged.
