Integral device for treating waste gas and high-concentration ammonia nitrogen containing waste water

Abstract

The invention relates to an integral device for treating waste gas and high-concentration ammonia nitrogen containing waste water. The integral device comprises an ammonia nitrogen stripping zone, a gas gathering zone, a cleaning and dedusting zone, a defogger, an activated-carbon adsorption layer and an exhaust fan; the ammonia-nitrogen stripping zone is provided with a precipitate discharge valve, an air intake tube, an air distribution tube, a waste water intake tube, a waste water distributor, a three-phase separator and an waste water discharge tube; the waste water intake tube is connected with a lye adding and metering mechanism; the gas gathering zone is provided with a gas-liquid separator, a gas gathering hood, a gas gathering tube and a stripping air pump, wherein the gas gathering tube and the stripping air pump are connected with a sulfuric acid adsorption tank; a waste gas cleaning and dedusting zone is provided with a treated water spraying device, a waste gas intake tube, a waste gas distribution tube and a treated water circulation pump; the middle part of the integral device is cylindrical, and the upper end and the lower end of the integral device are shaped like conical tanks; the integral device is arranged vertically; and the topmost conical tank of the integral device is provided with the exhaust fan.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to an integrated device for treating waste gas and high-concentration ammonia nitrogen wastewater. Background technique [0002] In recent years, with the rapid development of the economy, the discharge of waste gas and waste water has continued to increase, and the haze contained in the waste gas has caused severe haze weather; the nutrients such as nitrogen and phosphorus contained in waste water have made rivers, lakes and other water systems eutrophic The degree is increasing, destroying the function of the water body, breaking the original ecological balance, and the water environment is deteriorating day by day. [0003] At present, electrostatic precipitator and cloth bag dust removal are mostly used in the treatment of exhaust gas and dust pollution; stripping method, biological method and breakpoint chlorination method are mostly used in the treatmen...
