Abstract
The utility model belongs to the field of papermaking, and relates to a pulping and papermaking wastewater treatment system. The pulping and papermaking wastewater treatment system fully uses, and reasonably matches and integrates various advantages of a pulp reclaiming system, a sewage purification treatment tower, a water recycling system and a biochemical treatment system, and the systems are respectively connected with a pulping and papermaking workshop in a circulating manner; papermaking wastewater is filtered, precipitated and biochemically treated for several times through the pulp reclaiming system, the sewage purification treatment tower, the water recycling system and the biochemical treatment system, so that clean water and sludge in the wastewater are separated; moreover, the separated clean water is recycled in the pulping and papermaking workshop and excess parts are discharged on a standard, which not only greatly saves water consumption and water discharge in production but also guarantees finally discharged water completely on the standard; meanwhile, the sludge is completely recycled, which not only reduces production cost of enterprise but also relieves influence on surrounding environments; therefore, actual effects of energy conservation and emission reduction are achieved.
Description
Technical field
The utility model belongs to field of papermaking, relates to the wastewater treatment in pulping and papermaking processes, specifically, is a kind of system of pulp and paper effluent treatment.
Background technology
Paper industry always just belongs to the industry of high energy consumption, high pollution, in process of production, need to consume a large amount of tap water, can produce again a large amount of waste water simultaneously, and these waste water have, complicated component, bio-degradable are low, organic pollutant content high, belong to more unmanageable trade effluent, as can be seen here, first papermaking enterprise must pay a large amount of funds because produce water consumption, then the waste water again papermaking being produced drops into a large amount of physical resources and financial resources and processes, make it finally can qualified discharge, be unlikely to contaminate environment.
Summary of the invention
Production water loss can be reduced thereby the technical problems to be solved in the utility model is to provide one by paper-making effluent is processed and reclaimed, the system of discharged wastewater met the national standard can be made again.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pulp and paper effluent treatment system, comprises that pulping and paper-making workshop, recovery slurry system, the dirty water decontamination handles tower, water cycle are used system, biochemical treatment system and the input and output pipeline for connecting; Wherein said recovery slurry system comprises grid maker, slanted screen, screenings pond for recovering, screenings pump and sludge pump; Described water cycle use system comprises water collecting basin, secondary pond, second pond, three heavy pond, waste water lifting pump and constant voltage water pumps; Described biochemical treatment system comprises anaerobic pond and Aerobic Pond; Pulping and paper-making workshop is connected with grid maker, slanted screen successively by drainage pipeline, and slanted screen connects respectively screenings pond for recovering and water collecting basin, and screenings pond for recovering is connected to pulping and paper-making workshop by screenings pump and output channel; Water collecting basin is connected to the dirty water decontamination handles tower by waste water lifting pump and output channel, the dirty water decontamination handles tower is provided with three output channels, one of them is connected to pulping and paper-making workshop by sludge pump and output channel, another connects pulping and paper-making workshop by water delivery pipe road, also has one to be connected with secondary pond by water delivery pipe road; Secondary pond is connected to pulping and paper-making workshop by constant voltage water pump and output channel, connects in turn between secondary pond, anaerobic pond, Aerobic Pond, second pond and three heavy ponds by pipeline simultaneously; Second pond is connected with pulping and paper-making workshop with output channel by sludge pump with three heavy ponds, and three heavy ponds are also directly connected with secondary pond by an output channel in addition, and are also provided with a water discharge spout road.
Adopt technique scheme, by reclaiming slurry system, the dirty water decontamination handles tower, water cycle is used system and biochemical treatment system repeatedly paper waste to be filtered, precipitation and biochemical treatment, make the separation of removing contamination in waste water, and the clear water of separating is back to use to pulping and paper-making workshop to be recycled, redundance qualified discharge, production water loss and water displacement are so not only saved widely, the water that can also guarantee final discharge is also completely up to standard, simultaneously, the mud of separating also can 100% be recycled, so both reduced the production cost of enterprise, reduce again the impact on surrounding enviroment, thereby really reach the effect of energy-saving and emission-reduction.
The further technical scheme of the utility model is: also comprise PAC pond and the PAM pond of making up a prescription of making up a prescription, the described PAC pond of making up a prescription is connected to the dirty water decontamination handles tower by waste water lifting pump and output channel, and the described PAM pond of making up a prescription is connected to the dirty water decontamination handles tower by chemicals feed pump and output channel; The height of described the dirty water decontamination handles tower is that 18 meters, diameter are 16 meters; Described the dirty water decontamination handles tower is by sludge pump and output channel and be connected to pulping and paper-making workshop through sand separator; Described second pond is connected pulping and paper-making workshop through mud-collecting well, sludge digestion tank with sand separator with three heavy ponds successively again by the effect of sludge pump and output channel.These technique means, can allow removing contamination in waste water separate more fully, and the clear water of after separating and mud can be applicable to the recycling in pulping and paper-making workshop more.
