Bulk cargo terminal coal-containing sewage treatment system

Abstract

The invention discloses a coal-containing sewage treatment system of a bulk cargo wharf, which belongs to the field of sewage treatment and includes a stockpiling system and a sewage treatment system, and also includes a liftable baffle arranged around the stockpiling system; the stockpiling system is used for stacking coal , as a transfer station for coal transfer; the liftable baffle is composed of a number of liftable baffle units, if rainfall occurs, the liftable baffle will be driven up to form a channel between the stockpiling system and the sewage treatment system; according to the rainfall How much, adjust the bending degree, length and height of the channel appropriately; the sewage treatment system is used to treat the coal-containing sewage accordingly, and if the water quality of the treated coal-containing sewage meets the discharge standard, it can be recycled or discharged into the sea. The invention can slow down the speed of the coal-containing sewage entering the sewage treatment system, avoiding the untimely treatment of the sewage treatment system, and can also be used as a temporary water storage device to collect the coal-containing sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a coal-containing sewage treatment system of a bulk cargo terminal. Background technique [0002] Coal is usually transported by sea and land. Coal transportation in East China and South China is basically settled by sea. When transporting by sea, a stockyard is usually set up near the wharf. If it rains or washes the coal conveyor belt, coal-containing sewage will be generated. For example, the Chinese invention patent with the publication number CN106219269A discloses a coal wharf loading and unloading system, including a ship unloading system, a belt conveyor transmission system, and a stacking and reclaiming system. The belt conveyor transmission system undertakes horizontal transportation and transfer of coal. The machine conveying system is divided into a part of the belt conveyor in the yard and an unloading line belt conveyor. The ship unloading system is provid...
