Technical field
The present invention relates to a kind of Sewage treatment systems, particularly relate to the sludge drying pond of a kind of town domestic sewage processing system.
Background technology
Along with the enhancing of people's environmental consciousness, sewage disposal has become the Important Problems that national governments pay close attention to, China's sewage source mainly contains three, and the sewage produced in residents from villages and towns district dispersant type domestic wastewater, the centralized sanitary sewage in urban life district and Industrial processes.Utilize that to carry out purification to sewage in sandy soil be traditional wastewater treatment process, there are some shortcomings in existing this sewage water treatment method, the removal ability of TN and TP is lower, also needs to place the biochemical treatment tanks such as some denitrification ponds.
Sludge drying pond is the important aftertreatment device of Sewage treatment systems, current sludge drying has and adopts nature mummification, and also have and adopt hot blast mummification, its structure is varied.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the sludge drying pond of another kind of field town domestic sewage processing system, be applicable to small towns sanitary sewage disposal.
To achieve these goals, technical scheme of the present invention is as follows: the sludge drying pond of a kind of town domestic sewage processing system, comprise sludge drying pond body, it is characterized in that: wash plate is set in the body of described sludge drying pond and described sludge drying pond body is divided into two chambers in left and right, about this, the top of two chambers is respectively equipped with mud import, the bottom of described left and right chamber distinguishes arranged transversely permeable geotechnique layer of cloth from top to bottom, gravel bed and double-edged fine-toothed comb, described double-edged fine-toothed comb is arranged by some bars longitudes and latitudes and forms, its aperture is less than 3mm, distance is had between the base plate of described double-edged fine-toothed comb and sludge drying pond body, the lower end of the left and right chamber of described sludge drying pond body is respectively equipped with water port, this water port is positioned at the below of double-edged fine-toothed comb, awning is provided with above the body of described sludge drying pond.
Adopt such scheme, the mud import of two chambers is connected with the sludge pump of backwash settling tank with the sludge pump of the equalizing tank of manpower rapid-infiltration treatment system respectively, and the mud at two places is separated mummification, better separately utilizes so that follow-up.Natural mummification on permeable geotechnique layer of cloth, slag wherein, successively through gravel and double-edged fine-toothed comb, stops by filtrate, and filtrate returns the equalizing tank of manual controlled infusion, and sludge drying is effective, and structure is simple, and cost is low.
In such scheme: described double-edged fine-toothed comb is made up of batten or bamboo cane.Cost is low.
In such scheme: described water port arranges water shoot, this water shoot is layered on the base plate of sludge drying pond body, and this water shoot arranges prosopyle.
In such scheme: be provided with awning above the body of described sludge drying pond.
Beneficial effect: structure of the present invention is simple, arranges that easily floor space is little, and construction cost is low, and sludge drying is effective.
