Vehicle-mounted device for microbiological treatment of rare earth ammonia nitrogen wastewater

Abstract

The invention relates to a vehicle-mounted device for microbiological treatment of rare earth ammonia nitrogen wastewater. The vehicle-mounted processing system comprises a flat truck, a wastewater treatment tank, a ventilation mixing device, a bacterial liquid adding system, a temperature control system, a pH regulating agent adding system and a monitoring control system, wherein the wastewater treatment tank, the ventilation mixing device and the pH regulating agent adding system are sequentially distributed on a flat plate type carriage of the flat plate truck, and the ventilation mixing device, the pH regulating agent adding system and the bacterial liquid adding system are respectively connected with a treatment tank through a corresponding gas conveying pipe, a corresponding liquid conveying pipe and a corresponding conveying pipe. A large or medium-sized flat truck is adopted, and tail water can be treated at a short distance according to the characteristic that tail water treatment places are scattered. And the treated tail water is superior to the national requirements of Discharge Standards of Pollutants for Rare Earth Industry. The ton treatment cost is extremely low, benefits are extremely remarkable, and application and popularization are more convenient.

Description

technical field [0001] The invention relates to a device for treating rare earth ammonia nitrogen wastewater based on vehicle-mounted microorganisms. Background technique [0002] Southern ionic rare earths are valuable non-renewable and important strategic resources in my country. At present, the in-situ leaching mining process is mainly used, and ammonium sulfate is used as the leaching agent. Or the wastewater brought out by rainwater (hereinafter collectively referred to as ammonia nitrogen wastewater), these ammonia nitrogen wastewater will affect the local surface water quality for more than ten years, so efficient, safe and economically feasible supporting ammonia nitrogen purification treatment technology is required. At present, domestic and foreign ammonia nitrogen wastewater treatment methods mainly include ammonia distillation method, breakpoint chlorine method, chemical precipitation method, reverse osmosis membrane method and biological deamination method, among...

AI Technical Summary

Problems solved by technology

At present, domestic and foreign ammonia nitrogen wastewater treatment methods mainly include ammonia distillation method, breakpoint chlorine method, chemical precipitation method, reverse osmosis membrane method and biological deamination method, among which the cost of biological deamination method is relatively low, but due to the existing strains’ impact on carbon source The demand is high, and the rare earth tail water contains almost no carbon source, so a large amount of sugary carbon source needs to be added, and the cost is very expensive, so it cannot be popularized and applied in the industry

On the other hand, since the "in-situ" leaching mining process is mainly used, the retained and discharged ammonia nitrogen tail water is dispersed, and the centralized treatment of the dispersed ammonia nitrogen tail water requires a larger amount of engineering, a large investment, and high costs
