Description

Dirt separation and drying treatment system for intelligent environment-friendly toilet
Technical Field
The invention relates to the technical field of harmless treatment of excrement, in particular to a sewage separating and drying treatment system for an intelligent environment-friendly toilet.
Background
In order to prevent the pollution of the fecal sewage to the environment, the fecal sewage is generally concentrated and then is pretreated by a physical method, namely, mechanical equipment is adopted to separate solid matters and water in the fecal sewage, the separated solid matters can be directly buried, or the separated solid matters are used as garden greening organic fertilizers after innocent treatment, and the separated sewage is discharged into a municipal sewage treatment plant for treatment.
Currently, there are three main ways for pretreating fecal sewage.
The first treatment method is to use a coarse grid or similar simple equipment to perform solid-liquid separation on the fecal sewage and then discharge the fecal sewage into municipal sewage. The method is simple, but the treatment mode can only separate a small amount of impurities in the fecal sewage, and a large amount of feces can be attached to the separated impurities, and the problems of high pollutant concentration and high solid concentration still exist in the subsequent treatment.
The second treatment mode is that solid impurities in the fecal sewage are firstly crushed and then are subjected to solid-liquid separation through a screw conveyor. Because the crushing is carried out, the moisture content of the separated impurities can be reduced after the squeezing, the organic matter components can be reduced, and the landfill treatment can be directly carried out. However, the treatment mode requires complicated equipment composition and large volume, and is not suitable for being matched with small-sized sewage treatment equipment.
The third treatment mode is to discharge the fecal sewage after solid-liquid separation, desanding and dehydration into a sewage treatment plant. The impurity of this processing mode in to excrement and urine sewage is not smashed, and the grid equipment of system takes place to block up easily, and whole set of processing system structure is more complicated moreover, the volume is bigger, the cost is high and the working costs is expensive.
At present, vehicles such as airplanes, high-speed rails, motor cars and the like generally adopt a vacuum excrement collecting technology to collect excrement sewage. The fecal sewage has the characteristics of high pollutant concentration and high solid concentration, and the treatment difficulty of directly adopting small sewage treatment equipment to treat the sewage is higher. Not only the sewage treatment effect is unsatisfactory, is difficult to realize discharge to reach the standard, but also the equipment is shut down because of frequent occurrence of sludge blockage.
The scheme disclosed in the patent application is that a centrifugal roller is adopted to carry out solid-liquid separation on sucked dirt, the solid dirt is left in the centrifugal roller after the treatment process, the subsequent treatment of the centrifugal roller is very troublesome, and a spraying device is usually required to carry out spraying cleaning after the treatment. On one hand, the treatment process of the solid dirt is complex, and on the other hand, the solid dirt is not suitable for being used in an intelligent environment-friendly toilet adopting a vacuum excrement collecting technology.

In order to conveniently spray the excrement and sewage on the biological filler, the outlet end of the feeding pipe extends into the screen drum, the outlet of the feeding pipe is connected with an upward bent elbow pipe, and a flow baffle plate is arranged above the outlet of the elbow pipe. The slag discharging device comprises a spiral slag discharging device and a slag collecting groove communicated with the spiral slag discharging device, the main body of the spiral slag discharging device is arranged outside the box body, a slag inlet pipe of the spiral slag discharging device is communicated to the inside of the screen drum, and a slag discharging pipe of the spiral slag discharging device is communicated to the inside of the slag collecting groove.
