Problems solved by technology

If a systematic water seepage channel can be formed in the sludge body directly to the outside of the sludge, the dewatering efficiency of the sludge can be greatly improved, but there are almost no seepage channels of this type at present

Embodiment 1

[0043] Take a plastic mesh screen with a mesh size of 5 mm and a wire diameter of 1.2 mm, and trim it to round hanging board; take 4.42g of 60S / 2, 80% skin-friendly velvet and 20% fiber velvet blended thread, cut each thread to a length of 12cm, and tie each thread to the intersection point of the warp and weft threads of the screen to naturally sag; Every two columns on the left are twisted with 4 water seepage lines adjacent to each other (3 water seepage lines are twisted at both ends), if the last column is left, twist with two water seepage lines until all are twisted to form the first layer of weft net; The second layer of weft net is twisted with 2 adjacent water seepage lines in the first column, and 4 adjacent water seepage lines (three water seepage lines at both ends of the circle) are twisted with each other from the second column; the third The layer weft mesh twisting method is the same as the first layer weft mesh; the layer height of each layer of weft mesh is...

Embodiment 2

[0047] Take a plastic mesh screen with a mesh hole of 10mm and a wire diameter of 1.0mm, and trim it into a square hanging board of 100×100; take 2.56g of 60S / 2, 80% skin-friendly velvet and 20% fiber velvet blended yarn, and cut each strand to a length of 15cm , hang each wire to the intersection point of the longitude and latitude lines of the screen, and naturally droop; from the left, every two adjacent rows of 4 water seepage threads are twisted (the last remaining 2 wires are twisted), if there is one row remaining at the end, the water seepage is done in pairs The threads are twisted until they are all twisted to form the first layer of weft net; the second layer of weft net is twisted according to two adjacent water seepage lines in the first row, and every two adjacent water seepage lines in the second row are twisted together. Twisting; the twisting method of the third layer of weft mesh is the same as that of the first layer of weft mesh; the layer height of each lay...

Abstract

The invention discloses a construction method and applications of a water seepage channel capable of rapidly dewatering. The method comprises that hemp-cotton-velvet blended threads are tied at the warp and weft intersection points of a certain mesh hanging plate in a square or circular shape, and naturally sag; in the first layer of the weft net, the adjacent four threads (both ends of the circular hanging plate are three threads) in every two columns are mutually twisted, and then are separated to restore the arrangement corresponding to the square or circle; in the second layer of the weftnet, the adjacent two threads in the first column are twisted, and the adjacent four threads (both ends of the circular hanging plate are three threads) in every two columns are mutually twisted fromthe second column; the weaving of the third layer of the weft net is the same as the weaving of the first layer of the weft net, and the circulating is performed; and the water seepage threads adjacent to the water filtering pores on the bottom portion of a dewatering reactor are twisted into water filtering ropes with a diameter substantially consistent with the diameter of the water filtering pores according to the sizes of the water filtering pores, such that the three-dimensional interactive warp-knitted water seepage channel can be obtained. According to the present invention, the water seepage channel is filled in the sludge dewatering reactor, can obviously reduce the specific resistance of the sludge, accelerate the sludge dewatering, thicken the thickness of the pressure filtration sludge layer, increase the output of the pressure filtration sludge, and reduce the sledge dewatering cost.

Description

technical field [0001] The invention relates to a construction method of a fast dehydration seepage channel using three-dimensional interactive warp knitting, and belongs to the field of sludge dehydration treatment and disposal in environmental protection. Background technique [0002] Sludge dewatering has always been a worldwide problem. In recent years, with the continuous expansion of city scale and the further improvement of environmental protection requirements, the excess sludge produced by sewage treatment plants is also increasing day by day, which must be fully treated, and its moisture content is as high as 95-99%. implementation, a large number of rivers and lakes need to be cleaned and treated, which will inevitably produce a large amount of ecological dredging silt. These sludges need to be dehydrated to make the water content as low as 70% and below before final disposal. In addition, the production wastewater treatment of enterprises will also produce a la...
