Description
Technical field
The present invention relates to a kind of paper waste advanced treatment apparatus, particularly relate to one and process efficient, the simple paper waste advanced treatment apparatus of technical process, belong to Treatment of Industrial Water technical field.
Background technology
Paper waste Pollutant levels are high, complicated component, and quantity discharged is large, is one of main source of industrial wastewater pollution.When water pollutions is serious and water resources is day by day in short supply, qualified discharge and the reuse of paper waste become inevitable requirement.The process of paper waste is based on one-level materializing strategy and secondary biochemical treatment, and the water quality of bio-chemical effluent also exists and is difficult to stably reaching standard discharge or the problem of reuse, is mainly reflected in organic content and exceeds standard and colourity exceeds standard.Paper waste is after biochemical second-stage treatment, biodegradability is lower, its advanced treatment is generally based on physico-chemical process, as flocculation sediment, membrane filtration, absorption, technique based on flocculation sediment is limited for organic matter removal amount, along with discharge and the raising of reuse standard, the water outlet of such technique meets processing requirements by being difficult to; Processing contaminants removal efficiency based on membrane filtration is high, but investment and working cost higher; And the absorbing process based on charcoal absorption also exists investment and the high problem of working cost equally.And in recent years, chemical oxidation and the application of advanced oxidation in paper waste advanced treatment make the problems referred to above take on a new look to some extent, but still there is some problems, as patent CN 101708927 A provides a kind of advanced treatment method for papermaking waste water of oxidative degradation+flocculation sediment+sand filtration, the method has the advantages such as investment is little, working cost is low, but COD is lower than 70mg/L after treatment, discharge and the reuse requirement of increasingly stringent cannot be met.
Summary of the invention
The utility model provides a kind of and processes efficient, the simple paper waste advanced treatment apparatus of technical process.
The utility model device comprises bio-chemical effluent pond 1, chemical coagulation reaction tank 2, coagulative precipitation tank 3, strainer 4, catalyzed oxidation pond 5, intermediate pool 6 and clean water basin 7, and is connected by pipeline successively; It is characterized in that: coagulating agent groove 8 is connected with chemical coagulation reaction tank 2; Ozone generating-device 9 is connected with catalyzed oxidation pond 5, and intermediate pool 6 is connected with pH adjusting agent Preparation tank 10.
The utility model technological process is: first bio-chemical effluent pond 1 water outlet enters chemical coagulation reaction tank 2 and react, coagulating agent groove 8 is connected with chemical coagulation reaction tank 2, enter coagulative precipitation tank 3 to precipitate, water outlet is after filter 4 filters, enter catalyzed oxidation pond 5, ozone generating-device 9 is connected with catalyzed oxidation pond 5, for catalyzed oxidation pond 5 provides ozonated air, catalyzed oxidation pond 5 water outlet enters intermediate pool 6, intermediate pool 6 is connected with pH adjusting agent Preparation tank 10, and intermediate pool 6 water outlet enters the rear qualified discharge of clean water basin 7.
