  • Description: The invention discloses a papermaking wastewater treatment technology and treatment device. The technology mainly comprises steps as follows: wastewater produced in the digestion, washing and blanching process of alkaline papermaking and waste gas produced in the finished brick firing process in a machined brick firing kiln react, a water solution with the PH reaching 6-9 after the reaction is continuously circulated to be used for technological production steps of digestion and washing in alkaline papermaking and the technological production step process of stirring of machined brick materials, so that the technological process of treatment of wastewater produced in the papermaking technological process and the following recycling process of treated up-to-standard reaction water solutionsare realized. The wastewater treatment cost can be reduced with the papermaking wastewater treatment technology, and besides, zero emission of the treated wastewater can also be realized. 本发明公开了种造纸废水处理工艺及处理装置，主要包括将碱法造纸的蒸煮、洗涤
