The Invention discloses an ecological remediation method for controlling sulphur pollution in black and odorous sludge of rivers. Firstly, the sludge from pollution layer of the rivers will be dredged and stacked on the banksides with slope protection built along the outer edge of the sludge storage site; then innocent pretreatment will be conducted for the sludge. Specific steps comprise solarization and ploughing, and mixed ameliorant of certain proportion will be added for modification between first solarization and intermittent ploughing. Then, large emergent aquatic plants will be planted on the stacked sludge after pretreatment. The technical method provided by the Invention may control the release of acid-volatile sulfide in the contaminated sludge on one hand and reduce concentration of volatile organic sulfide in the waters on the other hand. With simple technical process and strong operable technology, the Invention meets the current requirements for controlling sulphur pollution in black and odorous sludge of rivers in China and facilitates realizing the goal of long-term control of sulphur pollution in the deposit of the waters.

A construction equipment location calibration apparatus that includes a method of use being operable to validate the geo-location of either construction equipment or an element thereof prior to executing a task such as but not limited to excavation. The present invention includes a plate assembly wherein the plate assembly includes a plate member. The plate member of is planar in manner and includes an upper surface. The upper surface of the plate member has alignment indicia thereon. The alignment indicia is operable to mark the center of the plate member and further provide a visual guide for a user to place an element of construction equipment thereon in order to validate the geo-location of the element ensuring correlation with the measured geo-location of the center of the plate member. The plate member includes a plurality of anchor members that are configured to secure the plate assembly into the ground.

A management system for a work vehicle, includes: a traveling condition data generation unit configured to generate traveling condition data that causes a work vehicle to enter with forward movement, from an entrance of a workplace to a work point of the workplace, and exit with backward movement, from the work point to an exit of the workplace; and an output unit configured to output the traveling condition data to the work vehicle.
