PORTABLE, NON-BIOLOGICAL, CYCLIC SEWAGE TREATMENT PLANT

摘要

A mobile sewage treatment and water reclamation system for rapid deployment to augment existing wastewater systems and provide interim service in lieu of permanent facilities, includes: (a) denaturing stage wherein raw sewage is first ground into suspendable grit, its pH first lowered to kill acid-sensitive bio-organisms, then raised to kill base-sensitive bio-organisms, and then neutralized; (b) clarifying stage employing an inverted-cone tank to circulate the solution after injection with chemicals to flocculate small particles for collection in a layer for siphoning off; and (c) disposal stage wherein clarified water passes through media filters to remove remaining solids and odors, the effluent water being clean enough for irrigation, aquatic life and discharge into waterways; and wherein sterile sludge is pressed into semi-dry solids, then dried, crushed, powdered and bagged for use as high-nitrate biomass fertilizer or for fossil-fuel power co-generation applications.

主权项

1. A portable sewage water treatment system comprisingsewage water intake means for receiving untreated sewage water and directing it into said treatment system in a sewage water stream;a clarifier coupled to said sewage water intake means said clarifier having
a tank having
a vertical axis extending between a top and a bottom;tank walls surrounding said vertical axis and defining a clarifier interior, said tank walls further defining
a holding chamber disposed adjacent said top, said holding chamber having substantially vertical, cylindrical sides extending a spaced distance below said top; anda circulating chamber disposed below said holding chamber and extending to said bottom, said circulating chamber having substantially conical walls converging at a select angle relative to said vertical axis from adjacent said holding chamber to adjacent said bottom;a sewage water stream injection port coupled to said circulating chamber adjacent said bottom and in fluid communication with said clarifier interior; andheader means disposed within said holding chamber and adapted to siphon a treated sewage water stream of treated sewage water from said clarifier;disinfecting means coupled between said sewage water intake means and said clarifier for non-biologically disinfecting said sewage;flocculation means coupled between said disinfectant means and said clarifier for causing solid materials suspended in said sewage water to precipitate out of solution and to clump together for removal;polymer treatment means for treating said sewage water to discourage flocculated solid materials from sticking to said tank walls within said clarifier interior; andfiltering means for filtering said treated sewage water.
