Abstract

The invention belongs to the technical field of sewage treatment, and discloses a membraneless solid-liquid and gas-liquid separator and system. The membraneless solid-liquid and gas-liquid separator includes a closed container, and a solid-liquid separation chamber is arranged in the closed container, and solid-liquid A gas-liquid separation chamber is arranged above the separation chamber, and the solid-liquid separation chamber and the gas-liquid separation chamber are isolated from each other by a diaphragm body. The solid-liquid separation chamber is provided with feed conveying pipe and slag discharge pipe. The solid-liquid separation chamber is provided with a counterflow pipe. The inlet end of the counterflow pipe extends into the middle of the solid-liquid separation chamber, and the outlet end of the counterflow pipe extends into the gas-liquid separation chamber. The gas-liquid separation chamber is provided with a liquid discharge pipe and an exhaust pipe, and the gas-liquid separation chamber is provided with a gas delivery pipe, and the two ends of the gas delivery pipe communicate with the solid-liquid separation chamber and the gas-liquid separation chamber respectively. The invention does not need power, can realize solid-liquid separation and gas-liquid separation of sewage, and the separated sediment, supernatant liquid and gas can be recycled again.

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...
