Description
Technical field
The invention belongs to technical field of sewage, be specifically related to a kind of Novel quartz sand filter.
Background technology
Be the water quality requirement that makes sewage reach a certain water body of draining or reuse, and to its process that purifies.Sewage disposal is widely used in building, agricultural, and the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink are also come into common people's daily life more and more.At present city domestic sewage discharging has been the main source that water pollutes.Press the sewage source classification, sewage disposal generally is divided into production waste and processes and sanitary sewage disposal.Production waste comprises trade effluent, rural sewage and medical sewage etc., and sanitary sewage is exactly the sewage that daily life produces, and refers to various forms of inorganic matters and organic complex mixture, comprises big or small solid particle floating and that suspend; Glue and gel diffusate and pure solution.Character by sewage is divided, and the pollution of water has two classes: a class is natural pollution; Another kind of is artificial pollution.Current to water body harm larger be artificial pollution.Water pollutes and can mainly be divided into chemical contamination, physical pollution and biologic contamination three major types according to the difference of polluting impurity.Pollutant mainly contains: unprocessed and the discharging industrial wastewater; Unprocessed and the discharging sanitary sewage; A large amount of farmland sewage that use chemical fertilizer, agricultural chemicals, herbicide; Be deposited in trade waste and the house refuse of river bank; Soil erosion and mine sewage.
Modern sewage disposal technology is pressed degree for the treatment of and is divided, and can be divided into one-level, secondary and tertiary treatment, generally determines the sewage disposal degree according to the whereabouts of the water after water quality condition and the processing.Two stage treatment is mainly removed the organic pollution materials that is colloid and dissolved state in the sewage, and clearance can reach more than 90%, makes organic pollution reach discharge standard, and usage comparison is short fiber widely at present, and it is good that removal efficiency reaches 95% outlet effect.
Sewage disposal device has many, but topmost following several types is arranged: centrifuge, sludge dewatering equipment, aerator, Microfilter, air floatation machine, filter; Filter is called again the media filtration system, and it is that a kind of filter medium that utilizes is removed in the water suspension, microorganism and other subparticles in each, finally reaches a kind of High-cfficiency Filtration equipment that reduces water turbidity, the effect that purifies water.Filter medium commonly used has quartz sand, activated carbon, anthracite, manganese sand etc.; Therefore cheap, simple in equipment are extensively applied to the every profession and trades such as agricultural irrigation, chemical industry, oil, metallurgy.Medium filter can use Single Medium, also can adopt medium according to different needs, and the filter of Single Medium also is shallow media filter, and its main filter medium is generally quartz sand, granite and volcanic pisolite etc.; The multilayer dielectricity filter also is profound medium filter, and its filter medium is comprised of more than one filter mediums, general quartz sand, activated carbon, anthracite, manganese sand and other contact media.More medium filter is to utilize one or more filter mediums, both adopted two or more media as the medium filter of filtering layer, in the industrial cycle water treatment system, in order to remove impurity in the sewage, the absorption wet goods, the requirement that water quality is met recycle, pass through certain thickness granular or non-grain material at the higher water of the lower turbidity of certain pressure, thereby effectively remove the process that suspended impurity makes clarification of water, filtrate commonly used has quartz sand, anthracite, manganese sand etc., be mainly used in the water treatment turbidity removal, demineralized water, the prime preliminary treatment of pure water etc., delivery turbidity can reach below three grades.
The present situation of sewage disposal all is high energy consumption, poor efficiency; at present city domestic sewage processing is the most important thing of at present and in the future urban water conservation and treatment work; this just requires us constantly to improve facility and the equipment of processing sanitary sewage, and is too impatient to wait thing.
