B. composite type biological filtering bed structure: whole bacteria bed divides totally four layers of top layer, main stor(e)y, bottom and supporting layers from top to bottom:
The top layer is a first layer, is mixed by mineralized waste and zeolite and forms top layer floor height 50～70cm.Its mesolite: mineralized waste=1: 0.5～5 mass percents, zeolite particle diameter are 0.5～3cm.Make the compound of the zeolite on top layer and mineralized waste because have strong ammonia nitrogen absorption ability, reach high efficiency so can guarantee processing.
Main stor(e)y is the second layer, and by floor height 1～2m, the mineralized waste of preferred 1～1.25m is formed.Main stor(e)y is mainly realized the quick absorption and the biological degradation of organic pollutant, the loading capacity and the loading capacity of mineralized waste are bigger, and microorganism active is vigorous, therefore be applicable to the poultry waster water that holds of high-concentration ammonia-nitrogen, can effectively remove the pollutents such as larger molecular organics, heavy metal and phosphorus element that hold in the poultry waster water.
Bottom is the 3rd layer, is that mineralized waste and the Wingdale of 25～35cm mixes by floor height.Wingdale wherein: mineralized waste=1: 5～8 mass percents, the particle diameter of Wingdale are 0.25～1cm.Owing to, therefore strengthened the nitrification and denitrification effect of bacteria bed as adding the Wingdale auxiliary material in the mineralized waste of bottom.
As undermost supporting layer by particle diameter 2～20cm rubble, preferred 2～4cm graded broken stone is formed, ballast grain sizes from top to bottom increases gradually, supporting layer height 8～15cm, adopt Open architecture, realize ventilating, make the supporting layer bottom to the filter bed natural reaeration, so that adapt to the processing that different sorts holds poultry waster water respectively with naturally.
Two. the operation of bacteria bed and control:
To rise to the bacteria bed top with pump through anaerobic treatment and the pretreated high density waste water of livestock poultry of coarse filtration, by flusher at bacteria bed top layer water distribution uniformity.Regulating the bacteria bed water distribution time is 1 with the ratio that falls to doing the time: 2-11 doubly.The control residence time of waste water in bacteria bed, the assurance mineralized waste is held back absorption and bio-transformation to pollution substance.The optimization operating parameter of bacteria bed is 1～8 hour for the water distribution time, handles the back waste water of livestock poultry at last and discharges through the supporting layer of bacteria bed, and water collecting basin in the middle of coming together in is finished whole scavenging process.Look the waste water quality situation, the mineralized waste bacteria bed can adopt 1～3 grade of series operation.
The present invention has following advantage
1. treatment effect of the present invention is good.Because the present invention adopts mineralized waste as main filler, and mineralized waste has bigger specific surface area, loose structure, waterpower conduction preferably and penetrating quality, suitable pH, cation exchange capacity (CEC) etc. preferably; And contain a large amount of and abundant microbial population, these microorganisms have very, and Johnson ﹠ Johnson deposits and degradation capability, therefore the various organic pollutants in the waste water of livestock poultry are degraded fully, all indexs such as SS, COD, BOD, ammonia nitrogen total phosphorus, intestinal bacteria quasi-microorganism, colourity are all up to standard.
2. denitrification effect of the present invention is good.The present invention is by adopting mineralized waste+zeolite compounding ingredient on the bacteria bed top layer, and the ammonia nitrogen absorption capacity of zeolite is bigger, can realize waterflooding during zeolite adsorption hold back ammonia nitrogen.Utilize the aerobic condition of natural reaeration to realize that ammonia nitrogen is nitrated in the dry spell that falls by the mineralized waste microorganism, and the ammonia nitrogen absorption ability of zeolite is regenerated.Also can realize the natural reaeration of filter bed bottom simultaneously by open supporting layer, whole bacteria bed from top to bottom form aerobic zone, hypoxic/anaerobic district, aerobic zone alternately, nitrated and biological denitrificaion creates conditions for ammonia nitrogen.
