Abstract

The invention discloses an absorption cleaning method of composting alkaline air. An absorption cleaning device of alkaline air comprises an absorption tower, a water pump and a bacteria liquid pool, wherein an air inlet pipe and an air inlet pump are arranged on one side of the lower part of the absorption tower; a liquid outlet is arranged on one side of the bottom of the absorption tower; alkaline air detection probes are all arranged at the lower part, the middle part and the upper part of the inner wall of the absorption tower; a discharge pipe and a discharge pump are arranged at the upper part of the absorption tower; a high-pressure atomizer is arranged at the top of the absorption tower; the liquid outlet is connected with the bacteria liquid pool through a pipeline; the bacteria liquid pool is connected with the water pump through a pipeline; and the water pump is connected with the high-pressure atomizer through a pipeline. Alkaline air introduced by the air inlet pipe is absorbed by atomized bacteria liquid of the high-pressure atomizer and reacts, the alkaline air is discharged out after reaching to discharge standard through system circulation, so that the absorption cleaning and discharge of composting alkaline air are completed. The method is high in absorption efficiency, and the used devices are small in occupied spaces; and moreover, bacteria liquid is recycled to the bacteria liquid pool after being discharged out through the liquid outlet, and then can be recycled after being adjusted through pH value, so that the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of pollutant discharge treatment, in particular to a method for absorbing and purifying compost ammonia. Background technique [0002] Composting refers to the process of continuously degrading and stabilizing organic matter through microbial metabolism under artificial control, and converting degradable organic matter in solid waste into a product suitable for land use; however, it is easy to produce in the composting process Ammonia gas is harmful to the human body and the ecological environment. At present, the absorption efficiency of ammonia gas in composting is low, and some can only meet the minimum national standard, which has a serious impact on the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the defect of low ammonia absorption efficiency in traditional methods, and provide a method for absorbing and purifying ammonia in composting. [0004...
