Description
Technical field
The invention belongs to the environmental engineering water-treatment technology field, relate to a kind of water treatment device, particularly a kind of compound tower ecological filter that is used for water treatment.
Background technology
Polluted water land (soil) treatment process is based on following characteristics, and sewage is had good denitrogenation dephosphorizing effect: the soil particle specific surface area is big, but effectively catching pollutants in sewage matter helps the enrichment of pollution substance; The various mikrobes of association in the soil, its vital process can consume a large amount of organism, helps the purification of sewage; Contain the nitration denitrification bacterium in the soil, generally need not pass through bacterization, can accomplish denitrification process; Soil has the good adsorption assimilation effect to phosphorus; Experiment shows; Yellowish-brown loam is 728.44 mg/kg to the absorbed dose of phosphorus, and rice soil is 989.72 mg/kg, and sand is 947.92 mg/kg; Be higher than general steel-making slag 323.19 mg/kg, and rice soil and sandy soil are a little less than flyash 1119.44 mg/kg.With the soil weight 1.30 g/cm
3Calculate every liter of soil phosphorus absorbed dose: yellowish-brown loam is 946.97 mg, and rice soil is 1286.64 mg, and sand is 1232.30 mg.Simultaneously; More because it has advantages such as easy and simple to handle, that working cost is low, polluted water land disposal method is as developed country, like the U.S., Australia; One of main mode of sewage on-the-spot disposal; Simultaneously, these class methods also have good application in China, also receive the favor of Chinese government departments concerned and unit further.(for example, the general ton in plant pool water floor space is 100 m but because general polluted water land disposal method ton water floor space is big
2, artificial swamp is 10 m
2), the water base expense of building of ton is higher relatively, and is easy to shortcoming such as obstruction, has limited the use of land disposal method in China, the use of especially vast Rural areas.To present situations such as China's rural area land used anxieties, the present invention makes full use of the advantage of soil (soil) WWT, in conjunction with the characteristics of bio-trickling filter, develops compound tower ecological filter.
