Embodiment Construction

[0025] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0026] Such as figure 1 , figure 2 As shown, an automatic anaerobic three-phase separation system is used to realize the treatment of wastewater, so that the three phases of gas, liquid and solid are well separated, the supernatant is discharged, and the sludge flows back into the reactor through the return slot of the three-phase separator to ensure Sludge concentration, biogas is directly discharged into the atmosphere after passing through the water-sealed tank, or is used as energy recovery. Its structure mainly includes reactor 1, a three-phase separator installed inside reactor 1, and water Packaging components and controllers.

[0027] The reactor 1 has a rectangular parallelepiped structure, and an overflow weir 2 is arranged at the upper end of a pair of parallel end faces. The interior of the reactor 1 is used to contain waste water.

Abstract

The invention relates to an automatic anaerobic three-phase separation system and a control method. The system comprises a reactor, a three-phase separator arranged inside the reactor, and a water-sealing assembly and a controller which are arranged outside the reactor, wherein the three-phase separator comprises a plurality of gas collecting hoods arranged in parallel, a gas collecting pipe communicating with the upper ends of the gas collecting hoods, and a gas chamber liquid level gauge installed on the upper end of any one gas collecting hood, the water-sealing assembly comprises a water-sealing tank, and a gas outlet pipe, a water inlet pipe, a water outlet pipe and a water-sealing liquid level gauge which are installed on the water-sealing tank, the gas collecting pipe extends into the water-sealing tank, a first valve is installed on the water inlet pipe, a second valve is installed on the water outlet pipe, and the controller is electrically connected with the gas chamber liquid level gauge, the water-sealing liquid level gauge, the first valve and the second valve, respectively. The three-phase separation system consisting of the three-phase separator with a double-layer inverted V-shaped structure, and a water-sealing tank is adopted, and the gas chamber pressure can be automatically adjusted through the coordinated control of the controller to match system operation.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an automatic anaerobic three-phase separation system and a control method. Background technique [0002] The anaerobic decomposition of wastewater treatment pollutants can be roughly divided into the following steps: 1) hydrolytic acidification stage; 2) acid and acetic acid production stage; 3) methane production stage. Among them, the stage of hydrolysis and acidification is to decompose the macromolecular refractory organic matter in water through the action of hydrolysis and acidification bacteria, open the ring and break the chain into small molecular organic matter that is easy to degrade; The products are further decomposed into volatile organic acids such as acetic acid and propionic acid; in the methanogenic stage, the volatile organic acids produced in the acidogenic and acetogenic stages or the hydrogen and carbon dioxide produced in the above stages are r...
