Description
Technical Field
The invention relates to the field of papermaking wastewater treatment and the field of dehydration devices, in particular to a rapid dehydration device and a dehydration method suitable for papermaking wastewater.
Background
The paper making industry uses wood, straw, reed, rag, etc. as raw materials, and separates out cellulose by high-temperature and high-pressure cooking, and then pulp is made. In the production process, the non-cellulose part in the discharged raw materials finally becomes black liquor for papermaking, and the black liquor contains lignin, cellulose, volatile organic acid and the like, has odor and strong pollution. The waste water from paper making is harmful, the black liquor is the most harmful, the pollutant content is more than 90% of the total pollutant discharge amount in paper making industry, and the black liquor has high alkalinity, deep color, heavy odor and more foam, and consumes a large amount of dissolved oxygen in water, thus seriously polluting water source and bringing harm to environment and human health. The most serious pollution of the middle section water to the environment is chlorine-containing waste water generated in the bleaching process, which poses serious threats to the ecological environment and human health.
The papermaking wastewater mainly comes from two production processes of pulping and papermaking in the production of the papermaking industry. The pulping process is to separate the fiber in the plant raw material to prepare pulp, and then the pulp is bleached, and a large amount of papermaking wastewater is generated in the process; the papermaking is to dilute, form, squeeze and dry the pulp to prepare paper, and the papermaking wastewater is easy to generate in the process. In paper industry, sewage contains harmful chemical inorganic substances, and also contains organic substances such as volatile phenol, precipitated solids, suspended substances, lignin, and the like. After the substances enter the water body along with sewage, dissolved oxygen in the water body needs to be consumed in the process of decomposing the substances by microorganisms, so that the oxygen content in the water body is reduced, and the growth and the propagation of fishes and other organisms are influenced. Such waste water is extremely harmful to human bodies, contains some heavy metal elements such as lead and the like, used chemicals cannot lose efficacy and still cause great harm to human bodies and the environment, if a paper mill is opened near a river, the waste water of the paper mill is discharged, but the influence of the treated water on the human bodies or the environment is small, and for people, people do not like to drink polluted water, so that the construction of the paper mill or some chemical plants is avoided. The fruit trees have poor growth and development, less blossoming and fruit bearing, poor fruit quality and no nutrition, and water source pollution and damage to people cause direct economic loss, thereby causing a series of problems.
Present papermaking waste water is mostly directly handled, and the impurity of aquatic can not obtain effectual clearance, and impurity and waste water are handled together after, if discharge together will cause the jam of discharge tube, on the other hand, because the humidity of waste water is great, papermaking waste water's the desiccation can need a large amount of time, is a difficult problem that hardly solves to some building fields, consequently, needs a device to solve the technical problem that meets at present urgently.
