Abstract
The utility model relates to biochemical ceramics made from waste water and mud and used for biological media, which belongs to the technical field of water treatment. The utility model is characterized in that the biochemical ceramics is in a shape of a honeycomb type brick or a honeycomb type cylinder. The biochemical ceramics can be used for the biological media in a biological filter, a trickling filter and a granular mud bed in anaerobic treatment, and can be used for reducing the eutrophication of the water body and constructing filtering dams for reducing the waste water pollution.
Description
Technical field
The utility model relates to a kind of biochemical ceramic as Biomedia that utilizes wastewater sludge to make, and belongs to technical field of waste water processing.
Background technology
Sewage work, paper-making industry waste water disposal facility and other biological wastewater treatment facility produce a large amount of waste gas mud.Because contain objectionable impuritiess such as a large amount of pathogenic bacterias, heavy metal in the mud, make the harmless treatment of mud and utilize the technical barrier that becomes international again.Make it be difficult to as fertilizer sources as objectionable impuritiess such as the pathogenic bacteria in the mud, heavy metals and use, traditional treatment process is dehydration, drying, carry out the refuse tip landfill, but the refuse tip landfill takies a large amount of places.Another processing mode is to take mode that aerobic burns reducing sludge volume, but produces objectionable impurities polluted air such as Dioxins in the burning process.Existing how empty medium generally has porous rock, slag or plastic medium, and porous rock, slag or plastic medium are widely used as filtration medium or bacterial adhesion growth medium.The void content of these media is few and can't fixation of bacteria.High velocity flow causes the bacterium that adheres on these media separated and wash away.CN101148346 (200710017127.4) provides a kind of method with preparing haydite from urban sewage plant sludge, is to be that raw material is mixed in proportion with dewatered sludge, flyash, clay, and the sintering that progressively heats up promptly makes haydite.The ceramic product that this technology obtains is the globular solids of yellow or brown.Fire for the utilization of wastewater sludge in the prior art and be mostly particulate state or fluffy powdery, can not satisfy the multiple needs of actual production.
Summary of the invention
This use novel pin provides a kind of novel biochemical pottery to the deficiencies in the prior art, is used for the biological media filtrate of wastewater treatment or the purification of eutrophication rivers and lakes, and fixation of microbe is used for wastewater treatment easily.
A kind of biochemical ceramic is characterized in that, ceramic shape is a cellular brick shape or cellular cylindrical.
The external diameter 5-20 of above-mentioned cellular cylindrical ceramic centimetre.
Biochemical ceramic of the present utility model is that the excess sludge by sewage work is main raw material, fires by the mould molding anoxic with addition of auxiliary materials such as lime carbonate or gypsum, clay, two water calcium hydroxides, liquid wax, iron powders and form, and can be used as the granular mud bed Biomedia in biological filter, trickling filter and the anaerobic treatment.Can also be used in the lake, filter the dam to reduce the pollution of waste water to reduce body eutrophication, to build.Beneficial effect is as follows: biochemical ceramic of the present utility model is a porous material, avoids biomass to be flushed away fixation of bacteria the time automatically; Need not artificial fixing; Selectable different shapes becomes base to make biochemical ceramic have application prospects more with size.Cost is low, is easy to commercial scale production.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1 biochemical ceramic.Fig. 2 is the structural representation of the utility model embodiment 2 biochemical ceramics.Wherein, 1, honeycomb hole.
Embodiment
Be described further this use is novel below in conjunction with embodiment, but be not limited thereto.
Embodiment 1: a kind of biochemical ceramic is that excess sludge by sewage work is that main raw material is fired and formed, and it is characterized in that ceramic base shape is a honeycomb brick shape base, in a straight brick shape base some honeycomb holes 1 is arranged, as shown in Figure 1.
Embodiment 2: a kind of biochemical ceramic is that excess sludge by sewage work is that main raw material is fired and formed, and it is characterized in that ceramic base shape is cellular cylindrical blank, some honeycomb holes 1 is arranged, as shown in Figure 2 in a cylindrical base.
Claims (2)
1. a biochemical ceramic is characterized in that, ceramic shape is a cellular brick shape or cellular cylindrical.
2. biochemical ceramic as claimed in claim 1 is characterized in that, 5-20 centimetre of cellular cylindrical ceramic external diameter.
