Abstract
The invention relates to an underground biological filter. The technical scheme of the invention is as follows: an underground biological filter comprises a filter trough, wherein the filter trough is paved with an anti-seepage geomembrane, a filter layer and a planting soil layer from bottom to top, plants such as a crop and the like are planted in the planting soil layer, a water distribution branch pipe is paved between the planting soil layer and the filter layer, a water outlet is formed on the lower part of one side, opposite to the water inflow end of the water distribution branch pipe, of the filter trough, the water outlet is communicated with a water collecting channel, and a lift pump and/or a water discharge port are/js arranged in the water collecting channel. The underground biological filter provided by the invention not only has the advantages of common biological filters, such as good purification effect, high BOD5 (biological oxygen demand in 5 days) removal rate (95% or higher), stable running, easiness in management and low resource consumption, but also can be used for overcoming the defect that the common biological filter can generate filter fly, and ensuring that sewage enters the filter through the water distribution branch pipe without off-odor emission and meets the requirement on water environmental protection of a healthy residential area; and when the underground biological filter runs in winter, the upper covering soil plays a role in heat preservation so as to guarantee the running effect of the underground biological filter.
Description
Technical field
The present invention relates to a kind of sewage purification process and system, relate in particular to a kind of buried biological filter.
Background technology
It is good that ordinary biofilter has a treatment effect, and that the BOD5 clearance can reach is stable more than 95%, be easy to management, save resource; But its floor space is big, is unsuitable for the big sewage of treatment capacity; Filtrate is easy to stop up; Produce the filter tank fly, worsen environmental health; Nozzles spray sewage, therefore shortcoming such as give an offensive smell, has seldom been utilized in recent years.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming, and a kind of technical scheme of buried biological filter is provided, the technical program not only has the ordinary biofilter advantage: as good purification, the BOD5 clearance can reach more than 95%; Stable, be easy to management, save resource; And can overcome the shortcoming that ordinary biofilter produces the filter tank fly, sewage enters the filter tank by range pipe, can not give an offensive smell, and meets the requirement of healthy settlement to water environment protection; The top earthing has also played insulation effect during winter operation, guarantees its operating performance.
The present invention realizes by following technical measures: a kind of buried biological filter, it comprises the filter tank groove, described filter tank groove is equipped with geotechnological anti seepage membrane from bottom to up successively, by ceramics filling or/and plant plants such as being implanted with banker on sandstone or ceramics filling and the filtering layer of forming mixing of sandstone, plantation soil layer, the planting soil, be equipped with range pipe between plantation soil layer and the filtering layer, a side lower part relative with the range pipe feed-water end on the groove of filter tank is provided with water outlet, described water outlet is communicated with braiding channel, is provided with lift pump and/or water port in the braiding channel.
Concrete characteristics of the present invention also have, and the filter tank groove of above-mentioned buried biological filter is of a size of 8.0m*2.5m*1.3m, and the filtering layer in the groove of filter tank comprises the ceramics filling layer of 700-1000mm height, are positioned at the sand stone layer of the 200mm on the ceramics filling layer; The height of described plantation soil layer is about 400mm.
Above-mentioned filtering layer is provided with permeability cell, and permeability cell runs through the plantation soil layer and expose the end.
Above-mentioned filter tank bottom land has 0.01 the gradient by the range pipe feed-water end to the direction of water outlet.Utilize the current direction braiding channel after purifying.
Above-mentioned water outlet top is provided with two row's air inlet ports, forms airiness with permeability cell.
The braiding channel of above-mentioned buried biological filter also is provided with roof ventilator.Can strengthen oxidation effect like this.
Beneficial effect of the present invention is: it has the advantage that ordinary biofilter has, and as good purification, the BOD5 clearance can reach more than 95%; Stable, be easy to management, save resource; And can overcome the shortcoming that ordinary biofilter produces the filter tank fly, sewage enters the filter tank by range pipe, can not give an offensive smell, and meets the requirement of healthy settlement to water environment protection; The top earthing has also played insulation effect during winter operation, guarantees its operating performance.Though its floor space is big, when the use that does not influence the arable land.
