Abstract
The utility model discloses the biochemical filter tank of a kind of gac, comprise filter tank body, described filter tank body bottom portion is provided with rising pipe and backwash water inlet pipe, and filter tank bodies top is provided with water inlet pipe, the first backwash water shoot, vapor pipe; It is characterized in that: in described filter tank body, be provided with porous water distributor, felt layers, active carbon layer, quartz sand layer, pebbles bed course, porous water distributor from top to bottom successively, described pebbles bed course is provided with aerated conduit, and aerated conduit is provided with solarization air cap.The biochemical filter tank of gac described in the utility model, effectively can remove the water body organic or inorganic pollutent such as SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX.
Description
Technical field
The utility model relates to sewage treatment area, particularly the biochemical filter tank of a kind of gac.
Background technology
Biochemical filter tank is with soil self-purification principle for foundation, and on the practical basis of sewage irrigation, the artificial bio-membrane's treatment technology grown up through more original intermittent sand filtration pond and contact filter is a kind of novel biomembrance process sewage treatment process.Existing biochemical filter tank ubiquity the shortcomings such as water distribution weak effect, Biofilm Colonization weak effect, sewage water filtration effect be bad.
Summary of the invention
For the problems referred to above, the purpose of this utility model is effectively to improve biochemical filter tank water distribution efficiency, improves the biomembranous biofilm effect in filter tank, improves the biochemical filter tank of gac of wastewater treatment efficiency.
For achieving the above object, the technical scheme that the utility model proposes is: the biochemical filter tank of a kind of gac, comprise filter tank body, described filter tank body bottom portion is provided with rising pipe and backwash water inlet pipe, and filter tank bodies top is provided with water inlet pipe, the first backwash water shoot, vapor pipe; It is characterized in that: in described filter tank body, be provided with porous water distributor, felt layers, active carbon layer, quartz sand layer, pebbles bed course, porous water distributor from top to bottom successively, described pebbles bed course is provided with aerated conduit, and aerated conduit is provided with solarization air cap.
Preferably, described felt layers is also provided with the second backwash water shoot.
Adopt technique scheme, the biochemical filter tank of gac described in the utility model, effectively can remove the water body organic or inorganic pollutent such as SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX.
Accompanying drawing explanation
Fig. 1 is the biochemical filter tank structure schematic diagram of gac described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the biochemical filter tank of gac described in the utility model, comprise filter tank body 10, be provided with rising pipe 104 and backwash water inlet pipe 105 bottom filter tank body 10, filter tank body 10 top is provided with water inlet pipe 101, first backwash water shoot 102, vapor pipe 103; The first porous water distributor 11, felt layers 12, active carbon layer 13, quartz sand layer 14, pebbles bed course 15, second porous water distributor 16 is provided with from top to bottom successively in filter tank body 10, described pebbles bed course 15 is provided with aerated conduit 106, aerated conduit 106 is provided with solarization air cap, felt layers 12 is also provided with the second backwash water shoot 107 simultaneously.
Adopt aforesaid way, in the biochemical filter tank of gac described in the utility model, felt has very strong filter effect; Porous water distributor is by uniform for sewage water distribution effect; Gac has absorption, biological degradation double effects; Double filtering layer (quartz sand layer, pebbles bed course) integrates filtration and biological degradation; The unnecessary mud in biochemical filter tank is discharged by back flushing, promotes the new city metabolism of microorganism.Being particularly the biochemical filter tank of filtrate with gac, is using gac as biofilm carrier, utilizes the adsorption of gac and biomembranous Degradation, removes a kind of novel method of the biodegradable organic pollutant in water.
During concrete use, sewage is intake by upper end, biochemical filter tank water inlet pipe, evenly be covered with in the body of whole biochemical filter tank under the effect of porous water distributor, first sewage flow through felt layers, due to the filteration of felt, by suspended substance removal thick in sewage, prevent too fast saturated of follow-up charcoal absorption; At active carbon layer, gac is a kind of porousness carbon containing matter, has flourishing microporous structure and huge specific surface area, can by many chemical adsorbs on its surface; Water after charcoal absorption enters into the double filtering layer be made up of quartz sand layer and pebbles bed course, microbial film is grown above filtrate, COD, BOD in sewage produce degraded at this, ammonia nitrogen produces nitrated degraded, the filteration of filtrate has retained the suspended substance in water simultaneously, makes filter tank have extraordinary effluent quality; After for some time is run in filter tank, need to carry out back flushing to filter tank, filter material layer and the unnecessary active sludge of active carbon layer are got rid of timely, is beneficial to microorganism better metabolic.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
