Solid-liquid pollutant integrated cleaning device for offshore waters and cleaning method thereof

Abstract

The invention relates to a solid-liquid pollutant integrated cleaning device for offshore waters and a cleaning method thereof. The device comprises a ship body and a solid-liquid pollutant integratedcleaning system. The ship body is of a double ship structure. The solid-liquid pollutant integrated cleaning system comprises floating garbage collecting devices and a sewage cleaning device. The floating garbage collecting devices are symmetrically arranged on hoses on two sides of the ship body and each floating garbage collecting device comprises a barrel shell and a recovery basket mounted inthe barrel shell, and the lower end of the barrel shell communicates to the hose; the sewage cleaning device comprises a sewage collecting box, a sewage reaction box, a CCAS reaction box, a water quality detection box and a sewage collecting box which are connected successively, the sewage collecting box communicates to the hose, water filtered by the floating garbage collecting devices enter thesewage collecting box through the hoses, active sludge is contained in the sewage reaction box, an MBR membrane bioreactor is arranged in the CCAS reaction box, and a water quality detection device is arranged in the water quality detection box. By adopting a negative pressure principle and a CCAS process, the solid-liquid pollutant integrated cleaning device can clean solid and liquid pollutantseffectively, so that solids and liquids are integrally treated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and floating garbage cleaning in the offshore field, in particular to an integrated solid-liquid pollutant cleaning device and cleaning method for offshore waters. Background technique [0002] The ocean is the cradle of life and the treasure house of resources. The rapid development of human beings has also led to the deterioration of the marine environment. It is estimated that the global economic loss caused by marine ecological damage is as high as 13 billion U.S. dollars every year. Therefore, the monitoring and cleaning of marine pollution is very important. At present, a batch of marine cleaning machines that have appeared at home and abroad have large hulls, large displacement, internal combustion engine drive, manned driving, and poor maneuverability. Unable to adapt to daily, a small amount of cleaning needs. At the same time, its complex structure makes it expensive, making i...
