Artificial rapid infiltration tank, water vapor treatment process and artificial rapid infiltration filler preparation method

Abstract

The invention discloses an artificial rapid infiltration tank, a treatment process and a preparation method of an active biological filler. A water vapor treatment tank is provided with functional layers, the functional layers comprise a filler layer, a barrier layer and a supporting layer which are respectively used for culturing and inoculating microorganisms, carrying out grading filling and collecting water vapor, and the water vapor treatment process realizes purification treatment on wastewater and waste gas by utilizing an active biomass carbon filler. Compared with the prior art, the artificial rapid infiltration tank disclosed by the invention can realize dual purposes of water and gas purification, and is more sufficient in filler source, more controllable in cost, more controllable in quality uniformity of the filler, more reliable in safety, uniform in quality of the active biomass carbon filler, and more convenient to process, construct, manage and control. The phosphorus adsorption effect can be better exerted, and more space is fully utilized.

Description

technical field [0001] The invention relates to an artificial quick osmosis tank, a treatment process and a preparation method, in particular to an artificial quick osmosis tank, a water gas treatment process and a preparation method for an artificial quick osmosis filler. Background technique [0002] Artificial rapid infiltration technology is one of the sewage land treatment technologies including subsurface constructed wetlands. For details, please refer to the Chinese invention patent "Artificial Rapid Infiltration Sewage Treatment System Device" (application number CN200410073951.8, published in 2005 October 5), artificial rapid infiltration technology referred to as CRI, CRI technology has 30 years of research and application history, and gradually matured in 2004 and declared a patent for invention. The core of CRI technology is CRI filler, which is artificial quick-permeable filler mixed with natural river sand and mineral ore. A large number of microorganisms with...

AI Technical Summary

Problems solved by technology

[0005] 1. The efficiency of total phosphorus (TP) removal in the artificial rapid infiltration system is low, and the treatment of phosphorus depends on the adsorption of special fillers (ie fluorite, magnetite, limestone sand), and its adsorption capacity is limited. After many years of long-term use It is easy to reduce the efficiency of phosphorus removal and need to be replenished

[0006] 2. The process of removing ammonia nitrogen in the artificial quick infiltration system needs to consume alkalinity, while the artificial quick infiltration filler mainly relies on the use of limestone particles to provide alkalinity for the nitrification reaction of the system. It is also a consumable and needs to be replenished in the future, and all limestone particles are mixed with the filler Filling, and the nitrification of ammonia nitrogen is concentrated within 50cm of the surface layer, so it is useless to add limestone to the filler tens of centimeters thick in the lower layer, resulting in more waste

[0007] 3. The quality of natural river sand and ore sand used in artificial rapid infiltration is relatively unstable, especially the natural river sand used for ordinary fillers. Due to the limitation of transportation radius, the indicators of river sand composition, strength, and sphericity vary greatly from place to place, and even useful Machine-made sand replaces natural river sand, which makes it difficult to control the quality of fillers for each project, and the quality control of artificial fast-permeable fillers is unstable

At the same time, the source of ore sand and river sand used is unknown, and there are likely to be many complex associated mineral pollutants, such as heavy metals such as chromium, cadmium, arsenic, copper, lead, zinc, etc., which also makes artificial rapid infiltration technology not easy to use in drinking water or high Application in the field of quality water purification

[0008] 4. The artificial rapid infiltration system is only used to treat sewage or slightly polluted water, but not to purify gas. The scope of application is too narrow

[0010] In summary, the existing technology can not fully meet people's requirements, and needs to be improved urgently.
