Membrane-free solid-liquid and gas-liquid separator and system

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a membrane-free solid-liquid and gas-liquid separator and a membrane-free solid-liquid and gas-liquid separating system.The membrane-free solid-liquid and gas-liquid separator comprises a closed container; a solid-liquid separating chamber is formed in the closed container; a gas-liquid separating chamber is formed above the solid-liquid separating chamber; the solid-liquid separating chamber is isolated from the gas-liquid separating chamber through a diaphragm body; the solid-liquid separating chamber is provided with a feeding conveying pipe and a slag discharging pipe; a reverse flow pipe is arranged in the solid-liquid separating chamber; an inlet end of the reverse flow pipe extends into the middle partof the solid-liquid separating chamber; an outlet end of the reverse flow pipe extends into the gas-liquid separating chamber; the gas-liquid separating chamber is provided with a liquid drainage pipeand an exhaust pipe; a gas conveying pipe is arranged in the gas-liquid separating chamber; and two ends of the gas conveying pipe respectively communicate with the solid-liquid separating chamber and the gas-liquid separating chamber. According to the membrane-free solid-liquid and gas-liquid separator and the membrane-free solid-liquid and gas-liquid separating system, solid-liquid separation and gas-liquid separation of sewage can be realized without power; the separated precipitate, supernatant and gas can be recycled and reused.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a membraneless solid-liquid and gas-liquid separator and a system. Background technique [0002] With the continuous improvement of people's living standards, people's awareness of the protection of environmental resources is becoming stronger and stronger. People's lives will produce a large amount of sewage, which contains a large amount of organic matter and particulate matter. The discharge of these sewage will not only cause waste of water resources , and will cause great pressure on the environment. In order to solve this problem, people purify sewage into usable water for reuse to reduce the waste of water resources and reduce environmental pressure. Some existing sewage treatment devices include solid-liquid separators and membrane bioreactors. The solid-liquid separation effect of the solid-liquid separator in sewage treatment is poor, the treatment...
