Description
Technical field
the invention belongs to technical field of sewage, specifically, it relates to a kind of Performance of Constructed Wetlands Substrates brick and preparation method thereof, for the pollutent in artificial swamp steady removal water body.
Background technology
Along with social development, the continuous expansion of industry, the pollution that mankind's activity brings to environment aggravates, and wherein the pollution problem of water surrounding stands in the breach.A large amount of trade effluents, sanitary sewage, mining industry waste water enters among water body, and water surrounding and the mankind's life condition has been caused to great threat.
As half the most frequently used environmental Sewage treatment systems, artificial swamp has that low, the less energy consumption of investment working cost, treatment effect are good, the advantage such as beautify the environment, it utilizes the acting in conjunction of soil, filler, waterplant and microorganism to remove the pollution substance of sewage, reaches the effect of purifying water body.Filler, as matrix and the carrier of artificial swamp, is its important component part.The growth of the structure of filler and character pair current, plant, microbial process all tool have a significant impact, and the selection of filler can have influence on the effect that wetland is disposed of sewage.
At present, in artificial swamp engineering, the filler that uses mostly is spherical, rectangular parallelepiped and square build, and material be take sandstone as main.In construction, exist in operational process and be difficult for transportation, the problems such as inconvenient, interior porosity is wayward, current short circuit, obstruction, treatment effect are unstable of changing are installed.This novel wetland filler can solve rectangular parallelepiped for wet land system, current that square filler easily causes straight under, current short circuit, Ball-type packing hole is the problem such as obstruction easily; Flyash, cinder have good adsorptive power, Wingdale has and has good effect dephosphorization, the volcanics of porous be added with the apposition growth that is beneficial to the microorganism on wetland, and avoided the filler that single filler life-time service may cause to stop up, improved the treatment effect to sewage.
Summary of the invention
The object of the present invention is to provide a kind of stable Novel constructed wetland packing of installation and transportation, performance optimization, treatment effect and preparation method thereof of being convenient to, be intended to solve the deficiency of existing Performance of Constructed Wetlands Substrates.
Technical scheme provided by the invention is as follows: a kind of Performance of Constructed Wetlands Substrates brick, filler is positive hexagonal prism type, the length of side is 8-12cm, height is 40-50cm, by mass ratio be the particle diameter 3-10mm cinder of particle diameter 2-8mm Wingdale, 30-40%, the particle diameter <2mm clay of the particle diameter <2mm flyash of 5-10%, 15-20%, the particle diameter 3-8mm volcanics of 15-25%, the particle diameter 2-8mm modification infusorial earth of 5-10% and the water of 10-15% form.Determine porosity>=30% of this filler, volume density 1.2 * 10
3-1.5 * 10
3kg/m
3;, permeation rate 15-20m/h.
The present invention also provides the preparation method of above-mentioned Novel constructed wetland packing brick, and its concrete preparation process is as follows: first, at normal temperatures, above-mentioned various materials are stirred in proportion, wherein using clay as binding agent.Secondly, pouring slurry into the length of side is in 8-12cm, the high positive hexagonal prism mould for 40-50cm, and at 80-120Pa/mm
2pressure under compression moulding.Natural air drying after the demoulding, can make this Novel constructed wetland packing brick.
Innovation of the present invention is: by design, prepare a kind of six prismatic Novel constructed wetland packing bricks 1., solve current that in wetland engineering, rectangular parallelepiped filler brick exists straight under, short circuit, the easy blockage problem of Ball-type packing brick hole, thus sewage is effectively addressed; 2. filler brick forms and to comprise and Wingdale, cinder, flyash, clay, volcanics and modification infusorial earth filler grating is optimized.The use of multiple material can avoid the filler that single filler brick life-time service may cause to stop up, and the environment of the apposition growth that is more conducive to microorganism is provided, thereby improves the wastewater treatment efficiency of artificial swamp.
Accompanying drawing explanation
Fig. 1 is Novel constructed wetland packing brick perspective view.
Embodiment
As shown in Figure 1, a kind of Performance of Constructed Wetlands Substrates brick, is positive hexagonal prism structure, and its concrete size is as follows: the length of side is 8-12cm, the high 40-50cm of being.For fear of obstruction, the environment that is more conducive to attached growth of microorganisms is provided, improve the wastewater treatment efficiency of wetland, determine porosity>=30% of this filler, volume density 1.2 * 10
3-1.5 * 10
3kg/m
3;permeation rate 15-20m/h, filler brick by mass ratio, be the particle diameter 3-10mm cinder of particle diameter 2-8mm Wingdale, 30-40%, the particle diameter <2mm clay of the particle diameter <2mm flyash of 5-10%, 15-20%, the particle diameter 3-8mm volcanics of 15-25%, the particle diameter 2-8mm modification infusorial earth of 5-10% and the water of 10-15% form.
Preparation method: under (1) normal temperature, the Wingdale of each particle diameter, cinder, flyash, clay, volcanics, modification infusorial earth and water are added and stirred in proportion, wherein using clay as binding agent; (2) slurry being stirred being poured into the length of side is in 8-12cm, the high positive hexagonal prism mould for 40-50cm; (3) at 80-120Pa/mm
2pressure under be pressed into the shape shown in Fig. 1; (4) air-dry under state of nature after the demoulding.This filler is built installation by laying bricks or stones on clay compacting impervious barrier, convenient and swift, forms suitable space, can avoid conventional filler easily to stop up, transport and install the problems such as difficulty, the easy short circuit of current, improves the treatment effect of Wetlands on Wastewater.
