We claim: 1. An improved apparatus for UV wastewater purification in septic tank system having a septic tank and a drainfield, the apparatus being adapted for placement underground between a septic tank outflow pipe end of a septic tank and a drainfield, the apparatus comprising: a) an assembly of continuous polyvinyl chloride (PVC) piping, of no more than 4 inches internal diameter in the area of active treatment, comprised of an inflow section which includes a straight septic tank outflow pipe, a 90 degree elbow attached thereto, a 24 inch long straight pipe attached thereto and extending downward vertically to communicate with a means to reverse direction 180 degrees, and a vertical treatment chamber comprised of a 24 inch long straight pipe attached thereto and extending upward vertically to communicate with a 4 inch diameter PVC 'T' fitting, so located so that the outflow arm of the PVC 'T' fitting and outflow pipe at their bottom is no more than one inch below the top of the wastewater flowing out of the septic tank outflow pipe, with the top leg of the 'T' communicating through a 3? inch long PVC straight pipe to a 6 inch to 4 inch diameter PVC reducer to a 30 inch long 6 inch diameter PVC straight pipe which extends to above ground level and is removably fitted with a 6 inch waterproof PVC cap; b) an ultraviolet (UV) lamp means emitting ozone free ultraviolet radiation in a wavelength range having a bactericidal effect, including a power means, a means to monitor, and a means to control the ultraviolet lamp and septic tank system operation; c) a means to prevent inadvertent exposure of personnel maintaining the apparatus from exposure to UV radiation with resultant risk of blindness; d) a bottom insert, having a plurality of ports there through, fixedly installed in the assembly of continuous polyvinyl chloride (PVC) piping, just downstream from the means to reverse direction 180 degrees, to prevent passage of particulate from the outflow of the septic tank from entering the area of the UV lamp means and act as a flow restrictor thereto; e. a top insert, having a UV socket port there through, fixedly installed in the assembly of continuous polyvinyl chloride (PVC) piping at the point of mating of the 3? inch long PVC straight pipe to the 6 inch to 4 inch diameter PVC reducer to a 30 inch long 6 inch diameter PVC straight pipe which extends to above ground level and removably fitted with a 6 inch waterproof PVC cap, from which the UV lamp means extends downward, and f. a means for monitoring the illumination of the UV lamp means remotely and for controlling the operation of the UV lamp means and septic tank system. 2. The apparatus of claim 1, wherein the means to reverse direction 180 degrees from the 24 inch long 4 inch PVC straight pipe inflow section to the 24 inch long 4 inch PVC straight pipe section of the vertical treatment chamber is comprised of a 90 degree 4 inch diameter PVC elbow, a 4 inch diameter PVC straight pipe, and a 90 degree 4 inch diameter PVC elbow. 3. The apparatus of claim 1, wherein the power means and means to prevent inadvertent exposure of personnel maintaining the apparatus to UV radiation with resultant risk of blindness is comprised of an electrical power wire from a remote control box which communicates through a water tight electrical connection, through the top wall of the 30 inch long 6 inch diameter PVC straight pipe, in the area which is covered by the 6 inch PVC cap when it is in place, to an electrical wire ending in a unified plug, through which power travels through a UV socket cord to a UV socket and from which electrical wires carry power to and signals from a photocell set in a UV shield, which is comprised of a solid tube of sufficient length and diameter to fully cover the portion of the UV light from a UV light retainer, in the UV socket port in the top insert, to the UV socket so that no UV light rays escape there from, with the UV socket cord being of a predetermined length so that the UV light cannot be removed from the top insert unless it is unplugged from the unified plug thus turning off the UV light before it can be withdrawn from the UV shield. 4. The apparatus of claim 1, wherein the means for monitoring the illumination of the UV lamp means remotely and controlling the operation of the UV lamp means and septic tank system is comprised of a photocell, removably installed in a threaded photocell port in a UV shield, which electrically communicates, through a unified plug, having female plug receptacles, in an electrical wire to the UV lamp means, which sends an electrical signal to a remote control box, having an audible and visual warning means which activate when the UV lamp means is not illuminated, and a resultant electrical impulse to a control for the septic tank system to automatically shut it down when the UV lamp means is not illuminated. 5. The apparatus of claim 1, wherein the ultraviolet (UV) lamp means, emitting ozone free ultraviolet radiation in a wavelength range having a bactericidal effect, including a power means, a means to monitor and control the ultraviolet lamp and septic tank system operation, is comprised of a UV light, 31 inches in length, encased in a quartz crystal protective tube which has tube protection means at the end nearest the bottom insert, as well as a tube bumper and tube stringer means to protect it from damage by coming in contact with the quartz crystal protective tube and communicates through a UV tube connector to form a single unit to a UV socket with a short UV socket cord and male plug which mates with female plug receptacles In a unified plug, which is removably suspended from a UV socket port in the center of the top insert, the combination of the UV light, protective tube, UV tube connector and UV socket being permanently bonded together so that the entire combination is replaced when necessary, so arranged that the top of the surface of the wastewater does not extend to cover the top portion of the UV light so that the waste water is irradiated not only from the submerged portion of the UV light, but from above by the unsubmerged portion of the UV light as the wastewater flows out the outflow arm of the PVC 'T' fitting to the outflow pipe to the drainfield. 6. The apparatus of claim 5, wherein the protective tube is comprised of transparent Teflon (polytetrafluoroethylene). 7. The apparatus of claim 1, wherein the inside of the vertical treatment chamber is lined with a sheet of reflective material.
