Sludge transferring system and method used for underground sewage treatment plant

Abstract

The invention provides a sludge transferring system used for an underground sewage treatment plant. The sludge transferring system comprises ground rails, sludge boxes, receiving moving flat cars, a sludge transporting vehicle and moving units. The ground rails are laid on the ground of an underground floor in the underground sewage treatment plant, and the ground rails are provided with a main rail, receiving position rails connected with the main rail and a loading and unloading position rail connected with the main rail. The sludge boxes are used for containing sludge. The receiving movingflat cars are used for loading the sludge boxes, stop on the receiving position rails, and can move to the position of the loading and unloading position rail along the main rail. The sludge transporting vehicle can reach a negative layer or a ground layer of the underground sewage treatment plant. The moving units can move the sludge boxes at the position of the loading and unloading position rail to the sludge transporting vehicle. The treated sludge can be reliably transferred in an underground space and finally conveyed outside, the requirements that the sludge transporting vehicle is onlydesigned to reach the negative layer or the ground layer of the underground sewage treatment plant are met, and therefore the occupied area and the civil engineering cost of the underground sewage treatment plant cannot be increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sludge transfer system for underground sewage treatment plants and a sludge transfer method for underground sewage treatment plants. Background technique [0002] Currently, surface sewage treatment plants are located in the suburbs of cities. However, with the gradual increase of urbanization and the rapid appreciation of urban land, sewage treatment plants in the suburbs of cities are gradually centralized. Because of the distance cost of sewage transportation, it is impossible for sewage treatment plants to move outwards all the time, and underground sewage treatment plants can effectively solve this contradiction. At the same time, the distance between the surface sewage treatment plant and the urban area is too large, which affects the reuse cost of reclaimed water, while the underground sewage treatment plant also has advantages in recycling. The advantage of underground...
