Abstract
The utility model relates to an earthworm biofiltration pool which comprises a filtration pool body, wherein a first filter screen layer, an earthworm treatment layer, a filtration layer, a diversion layer and a second filter screen layer are sequentially arranged in the filtration pool body from top to bottom; the earthworm treatment layer is formed by mixing a matrix with wood blocks, wherein earthworms are inoculated in the matrix; the filtration layer is formed by powdery sawdust; the diversion layer is formed by gravels; a sewage discharging pipe is arranged above the first filter screen layer; a liquid collection pool is arranged below the second filter screen layer; a water discharging pipe is arranged at the bottom of the liquid collection pool. The capacity of the earthworm biofiltration pool for decomposing organic matters is greatly improved under the combined actions of the earthworms and microorganisms, so that the sewage treatment capacity of the earthworm biofiltration pool is improved; meanwhile, the denitrification and dephosphorization capacity of the earthworm biofiltration pool is increased; in addition, the serious defect of sludge plugging caused by the running of the common biofiltration pool is overcome.
Description
Technical field
The utility model relates to a kind of biological filter, is specially a kind of earthworm biological filter.
Background technology
Worm biological filter tank is a kind of novel Biotechnology To Wastewater Treatment, is on the basis of ordinary biofilter, to introduce the organic decomposition processing layer that includes specific earthworm kind.Because earthworm has the organic substance of eating, improve soil permeability (permeable, ventilation) and with microorganism act synergistically and promote the Ecological Functions such as degraded of organic substance, therefore, can improve the voidage of filtrate, promote the degraded of organic substance in sewage, and remove the sludge blockage phenomenon that may occur in filter tank, thereby improve processing power and the processing efficiency in filter tank.The introducing that earthworm is filtered decomposition layer, has not only improved the disaggregating treatment efficiency of dirty organic pollutants, but also has overcome this serious shortcoming of ordinary biofilter sludge blockage in service.Worm biological filter tank also has certain denitrification dephosphorization function simultaneously.
Worm biological filter tank is different from ordinary biofilter, thereby its filtrate is not identical yet.The good growing environment of earthworm and microorganism should be provided, make again whole filter tank have enough sewage treatment capacity.
Utility model content
The technical problem that the utility model solves is to provide a kind of earthworm biological filter, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of earthworm biological filter, comprise filtering basin body, in filtering basin body, be provided with successively from top to bottom the first filter mesh layer, dealing with earthworm layer, filtering layer, guide layer and the second filter mesh layer, described dealing with earthworm layer is matrix and wooden unit mixolimnion, and in matrix, inoculation has earthworm; Described filtering layer is pulverous wood sawdust; Described guide layer is gravel, and the first filtering layer top is provided with effluent outfall, and the second filter mesh layer below is provided with collecting tank, and the bottom of collecting tank is provided with rising pipe.
Further, on described effluent outfall, be connected with header, header is provided with sprinkler pipe.
beneficial effect
The utility model is under earthworm and microorganism acting in conjunction, improved significantly the ability of filter tank decomposing organic matter, improve the sewage treatment capacity in filter tank, also increased the ability of filter tank denitrogenation dephosphorizing simultaneously, also overcome this serious shortcoming of ordinary biofilter sludge blockage in service.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make of the present utility modelly to realize technique means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of earthworm biological filter, comprise filtering basin body 1, in filtering basin body 1, be provided with successively from top to bottom the first filter mesh layer 2, dealing with earthworm layer 3, filtering layer 4, guide layer 5 and the second filter mesh layer 6, described dealing with earthworm layer 3 is matrix and wooden unit mixolimnion, and in matrix, inoculation has earthworm; Described filtering layer 4 is pulverous wood sawdust; Described guide layer 5 is gravel, and the first filtering layer 2 tops are provided with effluent outfall 7, the second filter mesh layer 6 belows and are provided with collecting tank 10, and the bottom of collecting tank 10 is provided with rising pipe 11.On described effluent outfall 7, be connected with header 8, header 8 is provided with sprinkler pipe 9.The utility model is under earthworm and microorganism acting in conjunction, improved significantly the ability of filter tank decomposing organic matter, improve the sewage treatment capacity in filter tank, also increased the ability of filter tank denitrogenation dephosphorizing simultaneously, also overcome this serious shortcoming of ordinary biofilter sludge blockage in service.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. an earthworm biological filter, comprise filtering basin body, it is characterized in that: in filtering basin body, be provided with successively from top to bottom the first filter mesh layer, dealing with earthworm layer, filtering layer, guide layer and the second filter mesh layer, described dealing with earthworm layer is matrix and wooden unit mixolimnion, in matrix, inoculation has earthworm; Described filtering layer is pulverous wood sawdust; Described guide layer is gravel, and the first filtering layer top is provided with effluent outfall, and the second filter mesh layer below is provided with collecting tank, and the bottom of collecting tank is provided with rising pipe.
