Abstract

The utility model discloses a novel sludge drying pond, which includes a pond body and sludge collecting pipes distributed on the periphery of the pond body, as well as a sludge mixing liquid conveying pipeline penetrating through the pond wall and communicated with the pond body, wherein a porose dry sludge support plate is arranged inside the pond body; the free end of the dry sludge support plate is connected with an electric hoist; the electric hoist is arranged on the pond body through a fixing bracket to control the lifting of the dry sludge support plate; and a coarse gravel packing, a flock geotechnical cloth filter layer, a fine gravel packing and a silver sand filter layer are arranged at the bottom of the pond body from bottom to top. The novel sludge drying pond has simple principle and excellent construction quality, and is easy to construct; the perforation muddy water collection pipe is convenient for muddy water collection and less prone to blockage; the dry sludge support plate and the electric hoist are convenient for dry sludge cleaning, replace manual mud cleaning, and save labor force; the processing cost is low, and high-power mud scraping and absorbing equipment is not needed; the floor space is small, and the novel sludge drying pond is suitable for small sewage treatment plants; and mud-water separation is realized through the filter unit step-by-step in virtue of pore variation, and the drying and volume reduction effects are better.

Description

The Novel sewage sludge drying pond

Technical field

The utility model belongs to sewage treatment area, particularly a kind of Novel sewage sludge drying pond.

Background technology

Recycling and the environmental protection problem of deal with relationship production cost and the resource of mud.Existing sludge treatment mode mainly contains the equipment such as drying bed, centrifuge, pressure filter.Though adopt the mode of mummifying pool not need power consumption, need spacious place, treatment cycle is also longer.The cost of the mechanical means such as centrifuge and pressure filter is high, energy consumption is large, and applicable object is limited.

The utility model content

For the problem that prior art exists, the utility model aims to provide that a kind of principle is simple, processing ease, mummification subtract the Novel sewage sludge drying pond that holds effective suitable small sewage treatment plant.

The utility model provides a kind of Novel sewage sludge drying pond, comprise the pond body and be distributed in described pond body muddy water collection tube all around, and pass the mud mixed liquid transport pipe that pool wall is communicated with described pond body, the inside of described pond body is provided with the with holes dried mud supporting plate fixing with pool wall, the free end of described dried mud supporting plate with holes is connected with electric block, described electric block is located on the body of described pond in order to control the lifting of described dried mud supporting plate with holes by fixed support, and the bottom of described pond body is provided with the coarse gravel filtering layer from bottom to top, short flannel geotextile filtering layer, bird's-eye gravel filtering layer and fine sand filtering layer.

The described Novel sewage sludge drying pond principle that the utility model provides is simple, and construction is easy, and construction quality is controlled easily; Its perforation muddy water collection tube is convenient to the muddy water collection, should not stop up; Dried mud supporting plate with holes and electric block are convenient to dried mud cleaning, have replaced traditional artificial clear mud, labor savings; Processing cost is low, need not the high-power mud equipment of inhaling of scraping; Floor space is little, is applicable to small sewage treatment plant; 4 filtering units are set, utilize hole to change to finish step by step the mud-water separation mummification to subtract to hold effective.

Description of drawings

Fig. 1 is the structural representation in a kind of Novel sewage sludge drying pond that the utility model proposes.

The drawing reference numeral explanation

1-pond body; 2-coarse gravel filtering layer, 3-bird's-eye gravel filtering layer, 4-fine sand filtering layer, 5-short flannel geotextile filtering layer, 6-dried mud supporting plate with holes, 7-muddy water collection tube, 8-mud mixed liquid transport pipe, 9-electric block.

Embodiment

Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:

Please refer to Fig. 1, the utility model provides a kind of Novel sewage sludge drying pond, comprises pond body 1, is distributed in described pond body 1 muddy water collection tube 7 all around, and pass the mud mixed liquid transport pipe 8 that pool wall is communicated with described pond body 1.

Please refer to Fig. 1, described pond body 1 is skeleton construction, its inside is provided with the with holes dried mud supporting plate 6 fixing with pool wall, the free end of described dried mud supporting plate 6 with holes is connected with electric block 9, and described electric block 9 is located on the described pond body 1 in order to control the lifting of described dried mud supporting plate 6 with holes by fixed support.

Please refer to Fig. 1, the bottom of described pond body 1 is provided with coarse gravel filtering layer 2, short flannel geotextile filtering layer 5, bird's-eye gravel filtering layer 3 and fine sand filtering layer 4 from bottom to top.

During work, mud mixed liquid enters sludge drying pond 1 by mixed solution transport pipe 8, and muddy water mixed solution passes through particle diameter 1 ~ 6mm fine sand filtering layer 4,300g/m from top to bottom ²Short flannel geotextile filtering layer 5, particle diameter 10 ~ 20mm gravel packing 3,300g/m ²Short flannel geotextile filtering layer 5, particle diameter 20 ~ 30mm coarse gravel filtering layer 2, by different-grain diameter distribution controlled filter hole, realize the step by step filtration of muddy water, mud remains on the dried mud supporting plate 6 with holes, form mud cake through natural air drying, dried mud cake is by the interlock of dried mud supporting plate 6 with holes and electric block 9, with dried mud cake removal.After the mud mixed liquid mud-water separation, collected by perforation muddy water collection tube 7.

Described Novel sewage sludge drying pond principle is simple, and construction is easy, and construction quality is controlled easily; Its perforation muddy water collection tube is convenient to the muddy water collection, should not stop up; Dried mud supporting plate with holes and electric block are convenient to dried mud cleaning, have replaced traditional artificial clear mud, labor savings; Processing cost is low, need not the high-power mud equipment of inhaling of scraping; Floor space is little, is applicable to small sewage treatment plant; 4 filtering units are set, utilize hole to change to finish step by step the mud-water separation mummification to subtract to hold effective.

The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
