Novel marine sewage treatment device

Abstract

The invention relates to a novel marine sewage treatment device. The novel marine sewage treatment device comprises a regulating tank, an anoxic tank and an aerobic MBR (membrane bioreactor) tank which are sequentially communicated with one another; the air inlets of the regulating tank and the aerobic MBR tank are both connected with an aeration system, the chemical feeding port of the anoxic tank is connected with a chemical flocculation phosphorous removal system, the chemical feeding port of the aerobic MBR tank is connected with a pH automatically adjusting system, the inside of the aerobic MBR tank is provided with an immersed flat sheet membrane module, the membrane cleaning port of the aerobic MBR tank is connected with an online cleaning system, and the aeration system, the chemical flocculation phosphorous removal system, the pH automatically adjusting system and the online membrane cleaning system are all connected with an electric control system. The novel marine sewage treatment device is small in space occupation, high in reliability, low in system sludge discharging amount and energy consumption, and convenient to mount, operate and maintain.

Description

technical field [0001] The invention belongs to the technical field of ship anti-pollution equipment and water treatment, and in particular relates to a new type of ship domestic sewage treatment device, which is suitable for the treatment of domestic sewage and gray water generated on ships, and the treated water can be directly discharged to the outside of the ship. Greatly alleviate the adverse effects of ship sewage on the water environment. Background technique [0002] According to the definition of the International Maritime Organization (IMO), ship domestic sewage refers to any form of toilet and urinal discharge and other waste; medical room (pharmacy, ward, etc.) Effluents; effluents from spaces containing live animals; or other wastewater mixed with effluents as defined above. "Grey water" refers to drained wash water, kitchen sink water, shower water, laundry water, bath water, face water, etc. Marine sewage treatment technology is an anti-pollution equipment s...

AI Technical Summary

Problems solved by technology

[0004] There are some problems in my country's existing ship domestic sewage treatment technology, for example, the treatment efficiency of ship gray water is low, and it is difficult to meet the treatment requirements for efficient removal of pollutants such as nitrogen and phosphorus. The existing ship domestic sewage treatment devices are large in size and resistant to impact loads Poor capacity, unstable processing effect, short service life of supporting parts, inconvenient operation and maintenance

So far, there is no domestic sewage treatment system approved by China Classification Society that meets the discharge requirements of GB3552 for inland passenger ships.
