Description
Technical field
The present invention relates to a kind of flocculation agent and preparation method thereof, belong to the dirty water decontamination handles technical field.
Background technology
Sewage, be often referred to by certain that pollute, from life and the discharge water produced.According to the viewpoint of sewage source, sewage can be defined as from house, office, business or manufacturing district discharge and underground water.The liquid carrying refuse of the mixing such as surface water, snowstorm or water.Sewage is by many classifications, and correspondingly reducing sewage also has many technology and technique to the impact of environment.According to sewage source, sewage can be divided into this four class.The first kind: trade effluent, from the sewage manufacturing mining and industrial production activities, comprise from the runoff stored with industry or business, process Leachate site alive, and other is not the waste water of sanitary sewage.Equations of The Second Kind: sanitary sewage is from house, office building, office or similar sewage; Health sewage; Effluent sewerage, comprises the trade effluent mixed in sanitary sewage in sewerage.3rd class: business sewage exceedes nontoxic, the harmless sewage of sanitary sewage from commercial facility and some composition.As sewage from catering business.Using sewage of wash house, animal rearing sewage, the sewage etc. that hairdressing place produces.4th class: overland flow is from water under rainwater, snow-broth, motorway, and from the water etc. of city and industrial area, overland flow does not infilter soil, enters underground water along street and land.
In the water pollution that human production activity causes, the water pollution that industry causes is the most serious.As trade effluent, it is many containing pollutent, and complicated component, not only not easily purifies in water, and process is also more difficult.Industry waste water is the most important reason that industrial pollution causes water pollution.It accounts for the major part of the pollutent that industry is discharged.Pollutent contained by trade effluent varies because factory's kind is different, even same class factory, production process is different, and the quality and quantity of pollutent contained by it is also different.Industry is except the waste water of discharging directly injects water body and causes pollution, and solid waste and waste gas also can polluted-waters.First agricultural pollution is because farming or the reclamation of wasteland make soil surface porosity, the rainfall when soil and landform are not also stablized, and a large amount of silt flows in water, increases the suspended substance in water.Also have major reason be agricultural chemicals, chemical fertilizer usage quantity increasing, and the agricultural chemicals used and chemical fertilizer only have a small amount of attachment or are absorbed, all the other overwhelming majority remain in soil and in an atmosphere floating, by rainfall, enter surface water through washing away of rainwash and infiltrate surface water formation pollution.Urban pollution resource is because urban population is concentrated, and city domestic sewage, rubbish and waste gas cause water pollution to cause.Urban pollution resource is to the pollution of water body mainly sanitary sewage, and it is the mixed solution of the various sewage produced in people's daily life, comprising the sewage that kitchen, washing room, bathroom and lavatory are discharged.
Water resources is the most critical resource of human being's production life, but nowadays, ecotope is seriously damaged, and water pollution is serious, and the protection of water resources and the improvement of water pollutions become the problem that modern society pays close attention to most.China is the serious country of a drought and water shortage.Freshwater resources total amount is 28000 billion cubic meters, account for 6% of global water resources, be only second to Brazil, Russia and Canadian, occupy the 4th, the world, but only have 2200 cubic metres per capita, be only 1/4 of world average level, 1/5 of the U.S., be one of 13 countries that water resources is the poorest per capita in the whole world.After deducting the flood river rising in Ningxia and flowing into central Shaanxi stream being difficult to utilize and the groundwater resource being dispersed in remote districts, China's available Freshwater resources amount of reality is then less, about being only 11000 billion cubic meters, available water resource is about 900 cubic metres per capita, and its distributed pole is unbalanced.To 20 end of the centurys, in more than 600 city, the whole nation, there is insufficient water problem in existing more than 400 city, wherein more serious lack of water city reaches 110, and National urban lack of water total amount is 60 billion cubic meters.China's shortage of water resources, water pollutions are serious, severe water and soil erosion, water price seriously on the low side, water resource waste is serious.And southern water is many, northern water is few.Western water is few, many along seawater.According to monitoring, current national most urban groundwater by point-like to a certain extent and facial contamination, and has the trend increased the weight of year by year.The water pollutions be on the rise not only reduces the using function of water body, exacerbate the contradiction of shortage of water resources further, the strategy of sustainable development implemented China brings and has a strong impact on, but also the safe drinking water of serious threat to city resident and the health of the people.Along with urbanization and socio-economic development, soil is taken in a large number, and non-agricultural irrigation water demand is sharply increasing, agricultural with industry, rural area and city, produce and live, produce and ecology etc. all multiplex water contradiction aggravate further.Although China takes the strictest cultivated land protection measure, a large amount of farmlands and agricultural irrigation water source are taken by city and industry, and the impetus that cultivated land resource reduces is difficult to reverse, and the pressure of shortage of water resources increases further.
For at this shortage of water resources, when water pollutions is serious again, we need to process contaminated water, can again be utilized after making these contaminated water treatments.The coagulating treatment of water is one of key link in wastewater treatment, can go turbid scrubbing, reduces the pollution load of sewage subsequent disposal.And flocculation agent is the key factor determining coagulating treatment effect, all there is important impact to the situation of follow-up process flow operation, final outflow water water quality and cost etc.Flocculation agent totally can be divided into inorganic flocculating agent and organic floculant two class according to its chemical composition.
