Abstract
The invention relates to a combined filling material used for biological deodorization in a sewage treatment plant. The combined filling material has high porosity, a large specific surface area, small bulk density, high strength, small possibility of being compacted, and strong acid-alkali buffer capacity. The combined filling material provided by the invention is prepared by uniform mixing an inorganic filling material and an organic filling material. The combined filling material comprises volcanic rock, bamboo charcoal and pine bark in a weight ratio of 90-103: 45-53: 40-56. Compared with a common filling material used for biological deodorization, the combined filling material provided by the invention has the advantages of a large specific surface area, high porosity, low resistance coefficient of a filler layer, large biomass per unit volume, small bulk density and small possibility of being compacted.
Description
Technical field
The present invention relates to a kind of sewage treatment plant biological deodorization filler combination.
Background technology
Along with the raising of socioeconomic high speed development and living standards of the people, have a large amount of sanitary sewage every day and produce, in order to improve sewage treating efficiency, sewage treatment plant on number in the trend risen year by year.Sewage treatment plant can produce a large amount of foul smell in the process of process waste water, and these foul smell not only cause ambient air quality and have a strong impact on, harm ecological environment, but also can cause damage to the healthy of neighbouring resident.Along with the enhancing of people's environmental consciousness, factory's foul smell of how effectively disposing of sewage becomes one of focus of people's concern.
Biological odor removal method utilizes the metabolism of microorganism self to odorous substance of degrading, and is the deodorization technology developed rapidly in the last few years, advantages such as having reduced investment, operational administrative is simple, operating cost is low, be safe and reliable.
The biologic packing material that biological deodorizing uses is obtained by microorganism filler being tamed cultivation.Filler is the institute that microorganism perches, and is the core of biological deodorizing technology, has key effect to the treatment effect of odor pollution thing.Good filler, also should be cheap and easy to get except needs are applicable to more growth of microorganism, and support strength is good.Therefore, the prerequisite that the filler being suitable for sewage treatment plant biological deodorization has become this technology extensive use is developed.
Summary of the invention
Object of the present invention, being to overcome now Packed deficiency, providing the sewage treatment plant biological deodorization filler combination that a kind of porosity is high, specific area is large, bulk density is little, intensity is compacted greatly, not easily, buffer capacity to acid and alkali is strong.
For reaching goal of the invention, the present invention by the following technical solutions:
Filler combination of the present invention is mixed by inorganic filler collocation organic filler and combines, and each medium-weight is than being volcanic rock: bamboo charcoal: pine bark=90 ~ 103:45 ~ 53:40 ~ 56.The bulk density of filler combination is 440kg/m
3, porosity is 51.5%.
Volcanic rock of the present invention is pitchy volcanic rock, is of a size of 3 ~ 5cm.
Bamboo charcoal of the present invention is high temperature bamboo charcoal, and carburizing temperature 800 ~ 1000 DEG C, in the form of sheets, is of a size of 1 ~ 3cm, moisture content less than 12%, fixed carbon content more than 85%.
Pine bark of the present invention is strip, is of a size of 3 ~ 8cm.
The feature of filler combination of the present invention is, with the characteristic of acidic materials during volcanic rock has, buffer capacity to acid and alkali is strong, and after effectively avoiding longtime running, environment peracid causes producing bacterial growth suppressing, the neutral environment required for energy stable maintenance deodorizing growth.
The feature that filler combination of the present invention combines different filler is optimized, and has the advantages that porosity is high, specific area is large, bulk density is little, intensity is compacted greatly, not easily, buffer capacity to acid and alkali is strong.This filler combination is formed by proper proportion mixing by inorganic filler and organic filler, suitable growing environment can be provided for deodorizing bacterium, be conducive to deodorizing bacterium and form biomembrane on filler combination surface, overcome again that natural organic filler is easily degraded, easily blocked, the easy short circuit of air-flow and the local easily shortcoming such as anaerobism, also overcome the not easy to be filmed of inert inorganic filler and the large shortcoming of maintenance management difficulty simultaneously.
Accompanying drawing explanation
Fig. 1 is that filler combination of the present invention and independent pine bark filler are to the treatment effect figure of ammonia.
