The internal combustion engine together with industrial emissions transform 259b of their fuel into energy, the other 75~ is converted into useless by-products.
In accordance with a preferred form of the present process a waste gas purifying device comprises means for drawing waste emissions from a waste gas source, a dismountable washing tank attached to the waste gas drawing means by a discharge pipe wherein the discharge pipe guides the waste gas into a washing tank containing washing liquid in use, wherein a discharage opening is located adjacent to the bottom of the washing tank for waste water extraction and air cooling for adjacent storage awaiting transportation from first location to second location.
This waste gas purifying apparatus is suitable for industrial and engine waste gases when produced, an intem~ediate exhaust fan is used to guide the waste gas collection process after sufficiently washing and reacting to minimize the content of undesired components. The washed gas is then discharged into the ambient air while the accumulated toxic liquid is extracted, stored, awaiting transportation to a near ground surface aerobic biological processer employing partially submerged in$tailation in which the contaminated water is injected and used as a component part of a growth medium for organisms within the earth covered medium to degrade hydrocarbons in a aerobic environment venting to the atmosphere by plant growth, transpiration and moisture vapour pressure.

Practices of prior art suggest that for water contaminated by hydrocarbons, the most useful treatment methods satisfying T 5 environment standards are those which employ naturally occurring micro-organisms submerged to degrade hydrocarbons in an aerobic environment assisted by granular matrix to remove residual traces of organics within the water Treatment processes must balance the economy and construction, operation, maintenance, minimizing contaminant transfer into the ambient air.
~JMMARY OF THE INV,~NTION
The main object of this process is to provide an apparatus for purifying waste gases, especially from engines, comprising an exhaust collection unit having a water reservoir through which the gases are 5 passed and an apparatus in which the contaminated wafer is used as a component of a growth medium for organisms.
The present process related to a waste gas purifying system suitable for car and industrial waste emissions that produce high concentrations of toxic gases by dismountable and portable means.
10 Various air purifying devices have been developed to eliminate the problem of air pollution but have a complicated structure and a high price with limited purifying effect.
Accordingly this toxic gas purifying system is suitable for cars and industrial use where an intermediate air exhaust pump is used to guide 15 the toxic gas into a washing tank for filtration and a sedimentation process containing washing liquid which con be clean water capable of accumulating sufficient mixed toxic gas reacting to minimize the content of the undesired toxic gas awaiting transportation from first location to second location for aerobic biological treatment.
20 it is a further object of the present process to provide a near ground surface apparatus arrangement for treatment comprising a earth bioreactor for biotreatment having a toxic waste water inlet and means of a discharge under gravity pressure with upper portion of the biotreatment superimposed water treatment porous conduits disposed substantially horizontally inside the panelled conduits being adapted for retrieval from the biotreatment housing unit adapted to receive contact media of a porous section of the water treatment conduits acting to refain and favour the growing of micro-organisms having the ability to degrade hydrocarbons.
The waste water treatment conduits are disposed in the biotreatment chambers in a stationary relationship during treatment to permit continuity of flow to permit intimate successive contact of toxic water and off gases which contact media on each and every conduit for gradual treatment of toxic water as the toxic water flows downwards in the biotreatment arrangement an overflowing outlet substantially discharging treated waste water with an aerobic environment in the biotreatment conduits by means of an air flow adapted to provide an air flow through the water treatment chambers for gradual treatment of the off-gases as the off-gases flow upwardly in the biotreatment conduit process.
The bioreactor unit of the present process can also optionally include an accessory compartment adjacent to and sealed from the biotreatment arrangement ancillary equipment operatively linked to the toxic water inlet means and air flow means to allow operation of the bioreactor preferably to render the bioreactor fully operational as a self contained apparatus arrangement. The ancillary equipment includes components required to ensure optimal operation conditions for the apparatus.
Accordingly the detached transportable apparatus having cooling fens for treatable emissions in to a liquid reservoir for entrainments subsequently introduced into an earth biofilter system for biodegrading comprising a plurality of triangular perforated panels housing a slotted tube embedded in a saturated matrix supported by a honeycomb structure for biological organism treatment enclosed in a water impervious barrier with surface vegetation by capillary means.
The process provides for a efficient method to treat hydro-carbon contaminated toxic liquid and off-gases at relatively low capital and operating costs by a practical fully enclosed arrangement for vegetation and athletic sports operational throughout the year.
Accordingly the present process provides a near ground surface waste water purifying installation in which contaminated toxic liquid is used as a component part of a growth medium for organisms comprising a liquid impervious basin which has a base sides and open top for atmospheric conditions. The installation also includes waste liquid and aeration injection system to maintain and increase a dissolved oxygen content adjacent to the base of the water impervious basin. Means are provided for withdrawing and recycling treated water from the impervious basin at a point above the water injection system.
A water table is de~rned by the treated liquid withdrawal means the water table being below the top surface of the basin and treatment perforated conduits preferably in the form of turf grass and planting roots extending into the basin.
The waste water circulating through the biotreatment arrange-ment is treated and partially evaporated while providing water and nutrients to the grass or planting roots consequently the treated waste water withdrawn from the biotreatment area at a higher level is of a greater purity and had a smaller volume than the waste water initially injected into the treatment area.
While the embodiments of this process described as they apply to hydrocarbons, contaminated toxic water removed and transported from reservoir units located to be used as a component part of a growth medium for organisms, it is intended that they be extended to such practical applications as the injection of treated water containing high levels of selective organisms ohto and into contaminated soil to supplement and enhance the degradation of the hydrocarbons contained therein.

Claims (7)
1. According to the present process there is provided a process for removing pollutants from effluent air, comprising causing the air laden with pollutants, to be passed through a detachable water washing tank whereby the pollutants pass into the water, the purified air is exhausted to atmosphere and the now contaminated water is transported to an aerobic bioreactor comprising a partially subterranean installation into which the water is introduced to act as a component part of a growth medium for plant growth whereby pollutants such as hydrocarbons in the contaminated wash water are biodegraded for expiration to the atmosphere.
2. A process according to Claim 1 wherein the bioreactor includes waste water treatment conduit panels which have triangular shaped bottom porous sections to enhance biological activity of micro-organisms retained by contact with limestone in a sealing relationship with the bio-reactor to prevent seeping of water or gases around the conduit panels and walls of the bioreactor.
3. A bioreactor according to Claim 2 wherein said waste water treatment conduit panels are successively staggered from each other in order that one water treatment conduit is offset from the subsequent waste water treatment conduit panel thereby reducing channelling and providing optimal distribution of waste water throughout the bioreactor.
4. A bioreactor according to Claim 2 wherein contact media is a combination of rigid naturally occurring organic matter limestone acting as a bulking agent and softer porous and pliable naturally organicmatter acting as a growth agent for said micro-organisms.
5. A process according to Claim 1 wherein the bioreactor includes air flow means which comprises of a heater fan to provide fresh or heated ambient air in the bioreactor.
6. A process according to Claim 1 wherein the washing tank has gas inlet and gas outlet means.
7. A washing tank according to Claim 6 further comprising flushing tubes attached to said gas inlet and gas outlet means.
