Abstract

The invention discloses a foaming agent wastewater treatment device. The wastewater treatment device comprisesa wastewater pool, a sedimentation basin, a filter, a stripping tower, and an air stripping tower, wherein the wastewater pool is connected with the sedimentation basin; the supernatant in the sedimentation basin is fed into a mother liquor gauge tank, and the sedimentation liquor at the lower part of the sedimentation basin is fed into the filter; the supernatant in the filter enters the mother liquor gauge tank; the mother liquor gauge tank and an alkali gauge tank are respectively connected with a stirring pot; the stirring pot is connected with the stripping tower; the top of the stripping tower is connected with an ammonia gas recycling device, and the bottom liquor outlet is connected with a condenser; the condenser is connected with the air stripping tower, and the top of the air stripping tower is connected with the ammonia gas recycling device. The crystal substance in the wastewater is removed through the sedimentation and the filtering, the equipment blocking problem is solved, the ammonia nitrogen is removed through the stripping tower and the air stripping tower, and the wastewater can be safely discharged.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a foaming agent waste water treatment device. Background technique [0002] The condensation reaction in the production process of foaming agent will produce high-concentration condensation wastewater. The ammonia nitrogen content in the wastewater is high and difficult to deal with, which is the main technical difficulty at present. The ammonia nitrogen treatment technology in the prior art mainly includes stripping and blowing off method and electrochemical method, and electrochemical method is costly to deal with, and adopts seldom in industry, and stripping and blowing off method is the most common treatment technology at present, but steam stripping method in the prior art The blow-off method is easy to block the equipment pipeline, and the maintenance cost of the equipment is high. Contents of the invention [0003] In order to make up for the deficiencies of the prior a...
