Embodiment Construction

[0036] The waste composition includes a wide variety of compounds, waste sources and materials treatable by aerobic remediation with various microorganisms in a liquid environment with an oxygen source such as air. Anaerobic remediation is not part of the invention. Waste constituents generally include industrial, domestic, commercial, sewage, corrosive compounds, and the like.

[0037]The method and apparatus according to the invention eliminate carbonaceous compounds, odors, harmful compounds, toxic compounds, ammonium-containing compounds, ammonium, nitrogen dioxide, nitrogen trioxide, hydrogen sulfide, bio-sludge, and the like. More specifically, examples of industrial waste include hydrocarbons such as n-hexane, benzene, toluene, xylene and the like, alcohols such as ethanol, methanol, phenol and the like, ammonia, aniline, morpholine ( morphline) and their analogs, and waste from restaurant and food service operations that typically produce large amounts of fat, oil, an...

Abstract

Numerous different types of waste compositions generally in an aqueous environment are bio-remediated under aerobic conditions utilizing highly diverse and multiple microorganisms within a reactor. The process is carried out with the microorganisms attached or bound by a variety of different surface characteristics to packing substrates, located within the reactor, having high surface areas and high porosity in the form of small micropores. Multiple different types of substrates are generally utilized that efficiently dissolve air into the water, as well as to maximize the concentration and diversity of types of microorganisms. Reactors are utilized that desirably have tubes therein containing the multiple types of packings and microorganisms and contain at least one perforated chimney through which air can flow and optimize dissolving oxygen into the aqueous environment of the various bio-remediation stages.

Description

technical field [0001] The present invention relates to the aerobic bioremediation of waste constituents, ideally in a liquid environment, to be converted or reacted into harmless and / or desirable end products. The conversion is usually performed in a reactor containing a variety and often abundance of different types of packing matrices, such as different sizes, shapes, etc., to maximize the dissolution of oxygen from the air into the water and to increase the concentration of various microorganisms. The substrates have a very large surface area and have different surface chemistry and physical properties to absorb, bind or connect a very diverse and diverse range of microorganisms, enabling the most efficient treatment possible of the different constituents of the largest volumes of wastewater. An important aspect of the packing matrix is ​​that it is highly porous and has numerous micropores in it to help retain microorganisms therein. The reactor has one or more perforate...
