Abstract

A method and device for separating most of the waste material from sewage effluent, which incinerates a large portion of the waste to dispose of the waste in an environmentally safe manner. After separation, the aqueous by-product from the sewage effluent is substantially waste free, allowing easy disposition or further treatment. The apparatus includes a housing and a filter in the housing to which the sewage effluent is introduced. The solid waste materials are trapped in the filter with a substantially aqueous by-product discharged from the device. A switch senses entry of the sewage effluent, starting operation of a heating element and a microwave generator which operate to substantially incinerate the waste material into an ash particulate. The gaseous by-products of the incineration are vented to the atmosphere and the ash particulate is vacuumed into a temporary storage container.

Description

Waste treatment method and device

For example the present invention relates at emission source in the shop, dwelling house or similar place, handle the method and apparatus of effluent sewerage.Method and apparatus of the present invention is separated the most solid refuse in the effluent sewerage, and this solid waste burning is become grey shape particle, can be handled on easy, environmentally safe ground.

In general, the processing of effluent sewerage is that the health department with dwelling house or shop is connected to sewerage system, and main sewage treatment plant handles in municipal administration.That is, refuse mainly is ight soil and urine, be suspended in the water, and water is flushed to treatment plant.Such treatment plant generally uses chemistry and bacteriology facture, effluent sewerage is decomposed and purification.

Municipal treatment system like this is normally effective, but still has many weak points.At first, such sewerage system is not to grow on trees.For example, generally sewerage system can not be installed effectively in the rural area.In addition, even in the urban area, population rapid growth has also surpassed the ability to bear of water processing establishment down in some cases, must suspend and being connected of this system.The enlarging of sewage treatment plant and development are not only expensive, and need for a long time from being designed into to build up also.During being connected of such time-out sewage and sewerage system, the construction in dwelling house and shop is hindered, and increases to be suppressed.

In the not economical and practical rural area of the sewerage system that has treatment plant, be extensive use of manure pit and septic tank and handle effluent sewerage.Certainly, in some cases, raw sewage directly enters water channel.Manure pit and septic tank all have shortcoming, and they need use Bacteria destroyed solid waste, enter contiguous diafiltration field or run-off then, even enter water channel.Certainly, such draining may make manure pit or the septic tank of handling refuse stop up, and makes its most of inefficacy.Manure pit and septic tank also have a shortcoming, are exactly that they generally all need a large amount of fresh water to make these system's operations.

For having the fully septic system in the soil of diafiltration, its advantage is the water that can discharge diafiltration.Area on some many rock or many mountains, edaphic condition do not allow the operation that this class septic system is kept in enough diafiltrations or draining.In addition, excavation cost may be high to such system can't be installed.Also have another difficulty to be, manure pit and septic system all need carry out biology to solids and decompose or Bacteria destroyed in decay process.This decay process is tedious often for environment, and has potential health risk.

The someone has designed the sewage disposal system of some kinds of " on the spot " (being positioned at emission source), uses grinder to water pretreatment down, and uses storage tank to carry out further bacterium and decompose.United States Patent (USP) the 4th, 439 has been represented such sewage disposal system No. 317.Yet present this class " on the spot " sewage disposal system that proposes is not only complicated and expensive, and the health risk that has a lot of operational issues and interrelate with the generalization manure pit.

Therefore, if develop a kind of " on the spot " sewage water treatment method and equipment, the whole or most of refuses in the effluent sewerage are separated, and handled this refuse in a kind of effective, environmentally safe mode, so, should be a kind of technical progress.

Problem above-mentioned can both solve with waste treatment system major part of the present invention.That is, this waste treatment method and equipment thereof can be isolated most of refuse from effluent sewerage, and handle this refuse in a kind of environmentally safe mode.This refuse burns with equipment of the present invention, and remaining a small amount of grey shape particle is collected it in interim hold-up vessel.From effluent sewerage, isolate most of refuse, remaining " grey " water that purifies basically or the water component of discharging.This kind water component is further handled, perhaps be discharged into water treatment system under the common municipal administration.Therefore, need not be municipal the sewerage area of handling, the invention provides a kind of method that can replace common manure pit and septic tank, handle refuse, eliminated very expensive sometimes excavation cost and the problem relevant with septic system in a kind of environmentally safe mode.In the area that municipal sewage treatment system service is arranged, the present invention has handled the most of refuse in the effluent sewerage in a kind of environmentally safe mode, alleviates the burden of these municipal sewerage systems and the difficulty of scarce capacity.

In general, its separation equipment comprises a casing, an inlet is arranged in order to admit the effluent sewerage that flows into this casing.The filtration treatment of packing in the casing is to admit effluent sewerage, and filtration treatment is best, and at least a portion is made up of thick fused quartz glass fragment, in order to hold back most of solid waste.Filter medium preferably also contains a kind of absorber material, is contained in the place adjacent with the glass fragment district, in order to hold back and to purify short grained refuse (as finding) in urine.Water component or " grey " water leach from filter medium, and are handled or recycle, and this depends on concrete applicable cases.

Effluent sewerage enters this equipment, just begins the operation of cycle of treatment, to eliminate the refuse from filtering area.The place of disposition of heating component contiguous filter in casing, and when effluent sewerage enters, start working, so that make the refuse heating.In addition, radiation mechanism as microwave generator, also starts working, to improve the temperature of refuse.This refuse is burned in filter effectively, stays a small amount of grey shape particle." burning " term of Shi Yonging in this application, its implication comprise burning (burning) or burn (combustion), dehydration, or their any combination.When cycle of treatment finishes, remove mechanism's (as vacuum system) and start working, grey shape particle is transported in the interim storage container.
