Abstract
The invention belongs to the field of papermaking, and relates to a pulping and papermaking wastewater treatment system. The pulping and papermaking wastewater treatment system adopts reasonable collocation and integration by sufficiently utilizing various advantages of a pulp recycling system, a sewage purification treatment tower, a water recycling system and a biochemical treatment system, all the systems are respectively connected with a pulping and papermaking workshop in a circulating manner, and the papermaking wastewater is subjected to filtration, sedimentation and biochemical treatment for many times through the pulp recycling system, the sewage purification treatment tower, the water recycling system and the biochemical treatment system, so that clear water and sewage in the wastewater are separated, the separated clear water is recycled in the pulping and papermaking workshop for recycling, and the excessive part reaches the standard and is discharged, therefore, the water consumption in production and water discharge are greatly saved, and the finally discharged water can be ensured to completely reach the standard; meanwhile, the separated sludge can also be recycled by 100%, therefore, the production cost of enterprises is reduced, the impact on the surrounding environment is reduced, and the effects of energy conservation and emissions reduction are truly achieved.
Description
Technical field
The invention belongs to field of papermaking, relate to the wastewater treatment in pulping and papermaking processes, specifically, is a kind of system of pulp and paper effluent treatment.
Technical field
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 a large amount of waste water again 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
Thereby the technical problem to be solved in the present invention is to provide and a kind ofly by paper-making effluent is processed and reclaimed, can reduces production water loss, can make again the system of discharged wastewater met the national standard.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of pulp and paper effluent treatment system, comprises pulping and paper-making workshop, recovery slurry system, the dirty water decontamination handles tower, water cycle use 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 by water delivery pipe road, to be connected with secondary pond; 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 have so not only been 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, reduced again the impact on surrounding enviroment, thereby really reached the effect of energy-saving and emission-reduction.
The further technical scheme of the present invention is: the 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 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 and three heavy ponds are connected pulping and paper-making workshop through mud-collecting well, sludge digestion tank with sand separator successively again by the effect of sludge pump and output channel.These technique means, can allow and remove contamination separated more fully in waste water, and the clear water of after separating and mud can be applicable to the recycling in pulping and paper-making workshop more.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
