Description
Technical field
The present invention relates to chemical Treatment Technology of Sewage field, be specifically related to a kind of paper-making waste water treating agent and preparation method thereof.
Background technology
Along with the progress of the mankind and the development of industrial and agricultural production, people recognize gradually, water is not inexhaustible resource, but a kind of extremely valuable natural resources that not only there is economic worth but also there is restoring ecological environment, be the narrow resources that human society is faced with.Water resources total content is not enough, and spatial distribution is uneven is an important feature of China's water resources.According to incompletely statistics, at present, there is more than 100 national lack of water in the whole world, and wherein the country of serious water shortage has reached more than 40.The per capita water resources of China is only equivalent to 1/4 of world average level.Particularly in recent years, production and domestic water requirement constantly increase, and the problem of water resources deficiency becomes increasingly conspicuous.Meanwhile, China is also faced with the problem of water pollutions, exacerbates the shortage of water resources, annoyings national economy, and oneself becomes the principal element of restriction Sustainable Socioeconomic Development.Therefore, purifying surface water and administering contaminated wastewater is the final way solving water resources deficiency.
Sewage, be often referred to by certain that pollute, from life and the discharge water produced.Sewage mainly contains sanitary sewage, trade effluent and early-stage rainwater.The ill pathogen contaminant of principal pollutant of sewage, oxygen consumption pollutent, plant nutrient and toxic pollutant etc.Along with the development of the modernization of industry, the trade effluent of discharge also gets more and more, and brings very large impact to the life of environment and the mankind, if waste water processes not in time, not only directly affect Air quality, the quality of tap water, but also can in the physical and mental health of the remote effect mankind.
Existing industry, municipal wastewater treatment process have physical treatment process, method of chemical treatment and biological treatment.Physical treatment process is the simplest water treating method, and it reclaims the undissolved suspended contaminant in sewage by physical sepn effect, and physical treatment process can only process some simple wastewater treatments, but process is very incomplete, is difficult to reach emission standard; Chemical treatment method is with medicament process pollutent, comprising neutralization, flocculation, redox etc.; Biological treatment is the pollutant dissolution made by microbial metabolism in sewage, but the method investment is large, and running cost is high.
In the process of giving water and waste water, coagulation is treatment process conventional both at home and abroad.Precipitation process of coagulation is the basic operation unit for removing colloid and natural organic matter.Innovation and development chemical coagulation, simplify water treatment technological process, reduce working cost and the key of depuration quality of increasing water quality depends on the coagulation performance of used coagulating agent, the quality of coagulating agent performance directly has influence on the quality of water treatment final effect.So researching and developing water conditioner that novel height laughs at and material is one of direction given priority in water treatment environmental protection industry technical field, is the basis of Water Pollution Control Engineering innovation and development.Coagulating agent is mainly divided into compound (composite) coagulating agent of inorganic coagulant, organic coagulants, microorganism coagulating agent and novel development.Due to inorganic coagulant there is nontoxic (micro-poison), many-sided advantage such as inexpensive, raw material easily obtains, in coagulation water treatment technology, occupy very consequence, widely used by people always.Compared with inorganic coagulant, organic coagulants has that consumption is few, coagulation speed is fast, coexisted salt and envrionment temperature factor affect little, the treatment time is short, generates the advantages such as sludge quantity is few.
Paper industry is large, the heavy-polluted industry of water consumption, the organism (i.e. COD) of paper waste discharge accounts for China's trade effluent total amount of organic about 25%, serious environment pollution, therefore, paper making wastewater zero discharge is the production practical technique that a water saving and pollution treatment are laid equal stress on, having good economic benefit, also have obvious social benefit and environmental benefit, is also the necessary choice that paper industry realizes Sustainable development.
Paper-making industry traditional uses water rich and influential family, is also one of important source of pollution causing water pollutions.Along with expanding economy, enterprise faces the problem such as shortage of water resources, scarcity of raw material day by day, and on the other hand, water pollutions also can be caused more and more serious.The first place of current China paper-making industrial waste water quantity discharged and COD quantity discharged Jun Ju China all types of industries quantity discharged, paper industry is the most serious to the pollution of water surrounding.Paper pulp papermaking waste water mainly comprises the plain boiled water produced in cooking waste liquor, the middle section water produced in detergent bleach process and the copy paper operation that chemical method quality produces, and they all have serious pollution to environment.Therefore, how reducing the COD of paper pulp papermaking waste water, is a job with important social effect and economic benefit.
