Abstract

The invention belongs to the technical field of paper-making wastewater treatment, and in particular provides a paper-making wastewater resource recycling and treating process method and a paper-making wastewater resource recycling and treating system device. After the method and the device are used, a better paper-making wastewater treatment effect is achieved by means of ultrasonic pretreatment,the chemical oxygen demand (COD) removal rate can be increased by about 20%, and the total COD removal rate can reach 57-69%; after black liquid is treated by means of ultrasonic waves, the comprehensive toxicity is reduced, the sludge activity is enhanced, the active period shifts forward, and bone morphogenetic protein (BMP) of at the active period of methane bacteria is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment in paper mills, and in particular relates to a papermaking waste water resource recovery treatment process and treatment system equipment. Background technique [0002] The paper industry is an important pillar industry closely related to the development of the national economy and the construction of social civilization, but its previous extensive development mode has caused some pollution to the environment. The discharge of wastewater in the paper industry is large, and the untreated wastewater contains a large amount of pollutants, which consumes a lot of oxygen, is dark in color and smelly, and has certain toxicity. These pollutants have a certain impact on the quality of the receiving water body, and even destroy the ecological environment. Papermaking wastewater has a large amount of discharge, complex components, and difficult treatment. [0003] The wastewater produced by ...
