Description

A kind of quartz filter for advanced treatment of wastewater
Technical field
The present invention relates to technical field of sewage, relate particularly to a kind of quartz sand mistake for advanced treatment of wastewater Filter.
Background technology
The water quality requirement for draining a certain water body to make sewage reach or reusing, and the process that it is purified.It is dirty Water process is widely used in building, agriculture, the every field such as traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment, food and drink, Also the daily life of common people is come into more and more.City domestic sewage discharge at present has been the main source of water pollution. Classify by sewage source, sewage disposal is generally divided into production sewage treatment and sanitary sewage disposal.Production waste includes that industry is dirty Water, rural sewage and medical sewage etc., and sanitary sewage is exactly the sewage that daily life generates, and refers to various forms of inorganic The complex mixture of object and organic matter, including the size solid particle that floats and suspend;Gluey and gel diffusate and pure molten Liquid.Divide by the property of sewage, the pollution of water there are two classes:One kind is natural pollution;Another kind of is artificial pollution.Currently to water body It is artificial pollution to endanger larger.Water pollution can be broadly divided into chemical contamination, physical dirt according to the difference of pollution impurity Dye and biologic contamination three categories.Pollutant mainly has:Unprocessed and discharge industrial wastewater;Unprocessed and discharge life Sewage living;It is a large amount of to use chemical fertilizer, the farmland sewage of pesticide, herbicide;Stack trade waste by the river and house refuse;Water Soil is lost in and mine system engineering.
There are many sewage disposal devices, but most important has following several types:Centrifuge, sludge dewatering equipment, aerator, Microfilter, air floatation machine, quartz filter.Quartz filter, scientific name shallow media filter, it be using quartz sand as Filter medium the higher water of turbidity by the quartz sand filtration of certain thickness granular or non-grain, has under pressure The retention of effect ground removes suspended matter, organic matter, colloidal particles, microorganism, chlorine, odor and part heavy metal ion etc. in water, most Reach eventually reduce water turbidity, the effect that purifies water a kind of High-cfficiency Filtration equipment.It is mainly used for electric power, electronics, beverage, originally The various process waters such as water, oil, chemical industry, metallurgy, weaving, papermaking, food, swimming pool, municipal works, domestic water, cycle With the depth disposal field of water and waste water.
Existing quartz filter has the following defects:1. in use for some time, the upper layer quartz in filter Sand be easy is adhered to by sticky dirt, for a long time do not clear up it is easy to be hardened, and then influence percent of pass, cause filter efficiency to reduce;2. Filter layer design is unreasonable, typically quartz sand is filled into filter body, the filter effect of sewage is generally passed through with it Path length, the classified filtering crossed etc. are related, and the path that sewage passes through is longer, and filter effect is better, and if it is intended to making it The path length of process must generally increase the height of quartz sand filling, so not only increase the cost of quartz sand, also increase Add the cost of equipment, and increased height can not possibly be too high, it is too high also unreasonable, increase by a point height and filtering is imitated The influence of fruit is little, and increased filter effect and cost are disproportionate in other words.
Invention content
In order to solve the above technical problems, the present invention provides a kind of quartz filter for advanced treatment of wastewater, Simple in structure, reasonable design, good filtration effect is at low cost.
The present invention specifically uses following technical scheme to achieve the goals above:
A kind of quartz filter for advanced treatment of wastewater, including filter body, it is successively set on filter sheet Upper cover at the top and bottom of body and low head, the upper manhole being separately positioned at the top of upper cover and low head and lower manhole, mistake The water inlet of filter body left side top and the water outlet of servant hole bottom;It is connected with a water distributor, institute on the right side of the water inlet It states water distributor bottom and is uniformly provided with several leakage holes, and water distributor bottom is provided with a coarse filtration net, is arranged below water distributor It includes the 1 grade of quartz sand layer, 2 grades of quartz sand layers, 3 grades of quartz set gradually from top to bottom to have quartz sand layer, the quartz sand layer Layer of sand, 1 grade of quartz sand layer, 2 grades of quartz sand layers, 3 grades of quartz sand layers quartz sand particle size be sequentially reduced, 2 grades of quartz The bottom of layer of sand is inclined to set, and 3 grades of quartz sand layers are made of several coiled pipes arranged side by side, and the one of the coiled pipe End opening is connected to the tilting bottom of 2 grades of quartz sand layers, and the other end of the coiled pipe leads to water outlet.Sewage from water inlet into Enter into water distributor, then passes through the coarse filtration net filtration of water distributor bottom, then pass through 1 grade of quartz sand layer, 2 grades of quartz sands successively Then layer enters the coiled pipe one end open of 3 grades of quartz sand layers from 2 grades of quartz sand layer bottoms, flow away filtering in coiled pipe, most It goes out afterwards from water outlet.
Preferably, the water pipe that the water distributor is connected to by circular cavity and with circular cavity forms, the water pipe it is another End is threadedly coupled with water inlet.Sewage enters water pipe from water inlet, is then entered in circular cavity through water pipe, in circular cavity It after sewage is evenly distributed in body, flows out, can be filtered evenly into quartz sand layer from the leakage hole of bottom;Due to cloth Hydrophone bottom is provided with coarse filtration net, and water distributor can be stained with many impurity after prolonged use, and threaded connection can facilitate Water distributor, which disassembles, to be cleaned.
Preferably, the bottom of the filter body is provided with an activated carbon layer, another end opening of the coiled pipe with Activated carbon layer is connected to.Quartz sand layer, using one layer of activated carbon layer, is failed filtration treatment by sewage after quartz sand filtration Impurity removes, and is conducive to improve filter effect, improves effluent quality.
Preferably, the bottom of the activated carbon layer is evenly arranged with several water caps.The setting of water cap can be flushed out effectively Sludge sundries in sewage keeps the normal operation of filter water quality and quantity.
Preferably, the low head bottom is provided with 4 stabilizer blades.Be conducive to support fixed quartz filter.
Beneficial effects of the present invention are as follows:
1. present invention setting coarse filtration net first tentatively filters sewage, it can effectively alleviate the filtering of quartz sand layer Pressure extends cleaning cycle, mitigates workload, improves production efficiency.
2. quartz sand filtration layer is ingenious in design so that sewage carries out substep layering, improves filter effect, and 3 Grade quartz sand filtration layer design is serpentine-like so that the path that sewage flows away in same homalographic and the quartz sand of height expands 10 Times or more, the efficiency of filtering is greatly improved, and the cost of sewage disposal, the quartz sand particle size of 3 levels will not be improved again It is gradually reduced, it is progressive, sewage water filtration effect is greatly improved, effluent quality is improved.
3. coarse filtration net, quartz sand layer, activated carbon layer cooperate, it is ingenious in design so that the quartz filter for The good purification of sewage, and production cost is low.
