Description
Technical Field
The invention relates to the technical field of harmless treatment of excrement, in particular to a modular 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.
Therefore, the solid-liquid separator for fecal sewage disclosed in chinese patent application publication No. CN105174631A comprises a solid-liquid separator, a feeding pipe, a slag discharging device and a water pumping device connected with the solid-liquid separator, and a control device for controlling the solid-liquid separator, the feeding pipe, the slag discharging device and the water pumping device. The solid-liquid separation device comprises a box body and a screen drum which is arranged in the box body and can rotate, biological filler with microbial flora is loaded in the screen drum, a liquid storage area for collecting fecal sewage is arranged in the box body, and the liquid storage area is positioned below the screen drum. The solid-liquid separator for the fecal sewage can effectively intercept and degrade fecal solid matters, facilitates subsequent treatment of the fecal solid matters, and is suitable for miniaturized equipment.
In order to prevent materials from adhering to a filter screen on a screen drum, the box body is also internally provided with an air injection device which is positioned above the screen drum so as to conveniently dredge the screen holes on the screen drum, wherein the excrement sewage solid-liquid separator is disclosed in the Chinese patent application publication No. CN 105174631A.
In order to realize the clean discharge of the gas in the box body, the top of the box body is provided with a gas outlet, and a gas filter is arranged at the gas outlet. The screen drum is provided with an access hole for overhauling the screen drum and filling biological filler into the screen drum, and a cover plate is covered on the access hole.

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.
