An apparatus and a method for receiving sand-laden manure from a vacuum truck in a duty cycle begins by collecting water issuing through a flume valve in a mixing basin. The mixing basin includes a metering bulkhead which forms a weir having a weir height and includes a sand gate. The bulkhead impounds a pool of water to fill the mixing basin at least to the weir height, separating the mixing basin from a sand settling lane vestibule. The impounded water is present to receive a manure payload from the vacuum truck. Water issuing through a flume valve mixes with the received sand-laden manure to form a manure suspension. Water flow through the flume valve is interrupted once a selected volume of water and manure suspension has passed over the weir. Opening the sand gate releases the impounded manure suspension, water and settled sand to flow into the vestibule.

A computer-based method includes transparentizing a background color of a toolbar of a currently running application, extracting a dominant color of a picture currently displayed on a user interface of the application, and displaying the toolbar using a color based on the extracted dominant color as the background color of the toolbar, along with the picture on the user interface of the application, and when the displayed picture is moved up and down or left and right with a user operation, keeping the background color of the toolbar unchanged from the color based on the extracted dominant color when the displayed picture is not completely moved out of an operation interface, and recovering the background color of the toolbar to a default color when the displayed picture is completely moved out of the operation interface and the operation interface does not have a picture or a color to display.

The present invention provides a method and an apparatus for changing a background color of a toolbar with a dominant color of a picture. The method includes: transparentizing a background color of a toolbar of a currently running application; extracting a dominant color of a picture currently displayed on a user interface the application; and using the extracted color as the background color of the toolbar, and displaying the extracted color. In addition, the method further includes: automatically changing a button color of the toolbar according to the changed background color of the toolbar. According to the method or the apparatus provided in the present invention, display of an overall effect of an interface is more harmonious, and subject content is more obvious, thereby improving an effect of interface immersive experience.
