Double-valve double-disk adjustable water quality fluctuation generator and its use

Abstract

The invention discloses a double-valve double-disc adjustable water quality fluctuation generator and a use method thereof, belonging to the technical field of water treatment. The generator consists of a low-concentration water base flow Q water supply system, a low-concentration water reduced flow q1 water supply system, a high-concentration water matrix flow q water supply system, a high-concentration water deterioration flow q2 water supply system and a water quality mixer, wherein the low-concentration water base flow Q water supply system keeps the liquid level of a constant level water tank constant; the high-concentration water matrix flow q water supply system keeps the liquid level of a high level water tank constant; the high-concentration water deterioration flow q2 water supply system is connected into a suspended water tank by virtue of a vacuum breaker and then is connected into the water quality mixer by virtue of a water outlet pipe; and the low-concentration water reduced flow q1 water supply system is hung on a multi-hole disc through an outlet of a water outlet hose by virtue of an overflow type water distribution box. The double-valve double-disc adjustable water quality fluctuation generator can be used for producing rectangular and sine-like water quality continuous fluctuation water flow with required cycle, vibration amplitude, base flow and matrix concentration respectively, and test equipment is provided for a quantification performance test and a structure optimal design of an adjusting tank.

Description

Technical field: [0001] The invention belongs to the technical field of water treatment, and in particular relates to a double-valve and double-disk adjustable water quality fluctuation generator capable of generating rectangular and sinusoidal water quality fluctuations and a use method. Background technique: [0002] In the treatment of urban sewage and industrial wastewater, large fluctuations in water quality destroy the optimal dosing relationship between flocculant dosage and pollutant concentration in sewage treatment facilities, and break the relationship between the metabolic capacity of microorganisms in activated sludge and biofilms. The balance between the concentration of pollutants reduces the comprehensive efficiency of the treatment facilities of the sewage treatment plant, resulting in the effluent exceeding the standard, and the greater the fluctuation, the more unstable the treatment effect will be. For coking wastewater with strong toxicity and refractory...
