Abstract

The invention discloses a deep papermaking wastewater treatment device. The device comprises a filtering pretreatment system, an ozone generation system, an ozone contact advanced oxidation tower system, a residual ozone degradation pond system and an upflow biologic aerated filter system, wherein the filtering pretreatment system, the ozone contact advanced oxidation tower system, the residual ozone degradation pond system and the upflow biologic aerated filter system are connected in sequence, and the ozone generation system is connected with the ozone contact advanced oxidation tower system. The invention further discloses a deep papermaking wastewater treatment method. According to the device, the filtering pretreatment system, the ozone contact advanced oxidation tower system, the residual ozone degradation pond system and the upflow biologic aerated filter system are combined, so that papermaking wastewater can be deeply treated, and the treated wastewater meets the standards.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a papermaking wastewater advanced treatment device and a papermaking wastewater advanced treatment method. Background technique [0002] According to the requirements of "Water Pollutant Discharge Standards for Pulp and Paper Industry" (GB3544-2008), since 2008, new pulp and paper enterprises will implement the standard "Table 2 Water Pollutant Discharge Limits for New Enterprises", such as paper industry wastewater Emission of COD shall be ≤80mg / L, and ammonia nitrogen shall be ≤8mg / L. [0003] With the rapid development of the economy, the density of national land development is increasing, while the environmental carrying capacity is weakening day by day. As a key polluting industry, the paper industry has increasingly stringent environmental protection requirements. The paper industry implements "Table 3 Special discharge limits for water pollutants" The requirement is an inev...
