Ecological bank filtering building block

Abstract

The invention discloses an ecological bank filtering building block, which comprises a curve pipe, a front plug net, a back plug net, an upper baffle plate and ceramsite, wherein the meshes of the front plug plate and the back plug plate are smaller than the particle diameter of the ceramsites; the front plug net and the back plug net are respectively plugged into the front end and the back end ofthe curve pipe; the front plug net, the curve pipe and the back plug net jointly form a filter cavity; the ceramsite is put into the filter cavity; the upper baffle plate is fixed on the upper edge of the front end of the curve pipe and is inclined towards the incoming direction of the water flow; the two sides of the curve pipe are planes. The ecological bank filtering building block provided bythe invention has the advantages that the ceramsite is used as building blocks; when the water flow passes through the plug nets and the ceramsite, the filtering and self cleaning effects are achieved; meanwhile, the curve building block can be easily shaped; through the planes at the two sides, the splicing and building between the building blocks are very easy; in addition, the front plug net and the back plug net are fixed by dismountable connecting elements, so that the ceramsite can be conveniently replaced and cleaned.

Description

technical field [0001] The invention relates to an ecological embankment filter block, which can be used for sewage treatment. Background technique [0002] With the development of society and the continuous expansion of city scale, the amount of treated water in urban waterworks and sewage treatment plants is also increasing, and more and more water supply sludge and sewage sludge are produced. At present, a considerable part of sludge is mainly Some traditional methods are still used for treatment and disposal, including sanitary landfill, sea reclamation, incineration and so on. Landfill needs to occupy a large amount of land, so it is obviously not suitable for large-scale promotion; while discharge into the sea will harm the marine ecosystem and cause pollution without borders. The United States and EU countries have already banned sludge discharge into the sea; Higher, and prone to air pollution problems such as dioxin, so it is subject to greater restrictions. Howev...

Problems solved by technology

Landfill needs to occupy a large amount of land, so it is obviously not suitable for large-scale promotion; while discharge into the sea will harm the marine ecosystem and cause pollution without borders. The United States and EU countries have already banned sludge discharge into the sea; Higher, and prone to air pollution problems such as dioxin, so it is subject to greater restrictions

However, some other resource technologies, such as sludge hydrogen production, low-temperature pyrolysis oil production, and adsorbent production, are difficult to be applied on a large scale in a short period of time due to technical and cost constraints.
