NOVELTY - A chemical/biological wastewater treatment apparatus consists of a flow separation unit, a unit for disposing the separated solids, a sulfurous-acid generator (18), an enclosed detention vessel, a pH adjustment unit, and an environmental biological system. The flow separation unit is in communication with wastewater influent from a gathering system for removing suspended solids from variable wastewater flows forming a filtered wastewater and separated solids. The sulfurous-acid generator is in communication with the filtered wastewater.    USE - Chemical/biological treatment apparatus is used for treating saline wastewater with dissolved and un-dissolved solids (claimed).    ADVANTAGE - The chemical/biological treatment apparatus uses rapid sludge chemical dewatering technology in conjunction with an environmental biological system for treating the separated treated wastewater by land applying it for the propagation of biosynthetic fuels and other plants, and/or passing it through aqueous plant or microbial reduction of the dissolved solids and ammonia for biological oxygen demand compliance to produce water of sufficient quality to reduce the overall salt load. The apparatus also produces water of sufficient quality to meet open stream and ocean effluent discharge requirements. The conversion of municipal sludge into bio-solids accelerates the biodegradation of organic compounds, reduces the microbial population including pathogens, and renders the material microbiologically safe for agricultural use. The apparatus can be rapidly installed as mobile or permanent package sewage treatment system, and easily retrofitted into existing treatment facilities chemically to treat and recover wastewater solids and liquids for subsequent environmental biological usage and polishing.    DETAILED DESCRIPTION - A chemical/biological wastewater treatment apparatus consists of a flow separation unit, a unit for disposing the separated solids, a sulfurous-acid generator (18), an enclosed detention vessel, a pH adjustment unit, and an environmental biological system. The flow separation unit is in communication with wastewater influent from a gathering system for removing suspended solids from variable wastewater flows forming a filtered wastewater and separated solids. The sulfurous-acid generator is in communication with the filtered wastewater. Sulfur dioxide is injected into the filtered wastewater at a pH generating sufficient sulfurous acid, bisulfite, and free sulfur dioxide for disinfection, separation, odor suppression, and conditioning of any suspended solids to agglomerate and separate the suspended portion from the liquid fraction of the filtered and conditioned acidified wastewater. The enclosed detention vessel is structured to hold the acidified wastewater and capture any excess sulfur dioxide released from the acidified wastewater for re-injection into the wastewater influent, and retaining the sulfur dioxide/sulfurous acid/bisulfite wastewater at a pH of 1.5-4.5, depending on dwell time, for a period of time to deodorize and condition the sulfur dioxide/sulfurous acid/bisulfite wastewater until the suspended solids agglomerate and dewater by shedding water upon separation and drying, dissolved solids and ammonia are sulfur dioxide/sulfurous acid/bisulfite treated resulting in odor reduction and color changes of the conditioned solids and liquids, and required effluent disinfection occurs to meet disinfection limits and form conditioned wastewater. The pH adjustment unit is associated with the conditioned wastewater to reduce the biocidal properties of any free sulfur dioxide, bisulfite, and sulfite in the conditioned wastewater and provide the pH required for subsequent environmental biological treatment. The environmental biological system is provided for treating the pH-adjusted conditioned wastewater by land applying it for vegetation consumption, and/or passing it through aqueous vegetation, or microbial reduction of the dissolved and suspended solids and ammonia for biological oxygen demand compliance to meet applicable land and open water discharge limits. The environmental biological system comprises halophile organism.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the chemical/biological treatment apparatus.
