A conveyor belt cleaning and sanitizing apparatus includes a hollow porous roller situated on the obscured or return loop side of the conveyor belt, out of sight of the top or conveying surface of the belt. A perforated rod, positioned within the hollow porous roller, contains a cleaning and sanitizing solution, dispensable through a series of perforations in the rod. The cleaning and sanitizing solution is evenly distributed to the porous roller and dispensed outwardly through the hollow porous roller to remove any debris and bacteria from the conveyor belt without excess solution. The cleaning and sanitizing solution can be inserted in the perforated rod using a pump from a tank reservoir. The pumping system is capable of metering the amount of fluid for application to the belt, based on usage of the belt. A tray can be situated below the hollow porous roller to contain debris and fluids removed from the conveyor belt surface.

The control pod is positioned outside the mechanical room and adjacent the vehicle was equipment so that an operator of the control pod can directly view the wash equipment as the operator adjusts controls of the control pod to precisely regulate materials, such as chemicals and other treatment liquids, delivered by the wash equipment to a vehicle as the vehicle passes along a path.

A small-scale waste processing device includes a housing, wherein a conveying cavity is provided in the housing, a screw is rotatably provided in the conveying cavity, a rotating cavity is provided in the housing, and the rotating cavity and the conveying The cavity is connected, and a rotating block is rotatably provided in the rotating cavity. A squeezing mechanism is provided in the rotating block. A first filter is fixedly arranged on the right wall of the rotating cavity. The present invention can pass kitchen wastes through Most of the water is squeezed out, and then the water in the waste is thrown out by throwing water to make the waste more dehydrated. The discharged waste water can be directly discharged to the sewer, which avoids clogging of the sewer and saves maintenance costs. The dehydrated waste passes through Grinding and squeezing makes it difficult to make full use of the packing space during the later packing process of waste materials, and at the same time avoids the leakage of waste water from the waste materials, causing pollution to the environment.

The present invention utilizes one or more processes to immobilize a waste that contains one or more of radionuclides, hazardous elements, hazardous compounds, and/or other compounds present in the waste. Each of the processes create a barrier against leaching and diffusion of the wastes. The first barrier is created by integrating the waste with an immobilizing mineral. The second barrier is a layer of non-radioactive or non-hazardous material that covers the first barrier. The second barrier may be created using an overgrowth procedure or by sintering. The third barrier is created by a rock or glass matrix that surrounds the first and/or second barriers. The fourth barrier is created by ensuring that the rock or glass has the same or similar composition as the indigenous rock at the disposal site. The resultant rock or glass matrix is in equilibrium with the groundwater or local hydrothermal solutions that are saturated with components of the indigenous rock of the disposal area.
