Micro-power gas-stripping mud and water constant-flow device and processing method thereof

Abstract

The invention discloses a micro-power gas-stripping mud and water constant-flow device. A gas-stripping mud and water system comprises a gas inlet, a gas-stripping mud and water absorbing pipe and a mud and water outlet flushing head; a mud and water volume regulating system comprises a mud and water energy balance regulating tank, a constant flow water outlet area, a pulsating flow water outlet area, a constant flow water outlet pipe and a pulsating flow outlet pipe; the mud and water energy balance regulating tank and the constant flow water outlet area are connected through a separating plate which is provided with flow holes. The micro-power gas-stripping mud and water constant-flow device has the advantage of being controllable in regulation of gas-stripping mud and water constant flow, stable in outflow, less prone in splashing of output mud and water, capable of effectively avoiding blocking led by settled mud, smooth in gas-stripping mud and water pipes, and low in gas and energy consumption, thereby being applicable to industrial promotion and application and filling the gap in the fields of constant-flow gas stripping and accurate gas-stripping outflow control.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a micro-dynamic air-lift mud water constant flow device and a treatment method thereof, in particular to water and mud water extraction used in the water treatment process. Background technique [0002] The air lift device is used in the sewage industry to lift sewage or sludge. Using it to replace the traditional sludge lifting pump or sludge discharge pump can not only reduce the maintenance frequency of sewage treatment equipment, but also save this part of power consumption , It plays a very big advantage in the energy saving and emission reduction of enterprises. [0003] But there are following problems in the existing air lift device: (1) because of being subject to the influence of factors such as the fluctuation of air pressure, the fluctuation of gas volume and the height of liquid submergence, the water output of the existing air lift device and te...

Problems solved by technology

[0003] But there are following problems in the existing air lift device: (1) because of being subject to the influence of factors such as the fluctuation of air pressure, the fluctuation of gas volume and the height of liquid submergence, the water output of the existing air lift device and technology is a pulsed water output, and the water output cannot It is a constant flow, and the flow is difficult to accurately control and adjust; when the existing device is used in the sewage treatment field of water extraction, reflux nitrification liquid, and muddy water, it cannot realize controllable constant flow liquid extraction, which seriously limits its further application. ; (2) The gas extraction outlet, due to the increase of the gas volume and the small amount of gas release, affects the stability of the air pressure in the pipe, the energy consumption is high, and the muddy water is released and splashed, resulting in less liquid extraction in the effluent; (3) Gas extraction The mouth is submerged in the lifting water level, resulting in secondary backflow of the muddy water after airlifting. The gravity of the backflow counteracts the upward airlifting force of the airlifting liquid, which consumes high energy and results in significantly less liquid lifted by the effluent.
