Embodiment 1

[0031] Taking a certain domestic sewage as an example, the performance of the system for nitrogen and phosphorus removal and organic matter removal was investigated. The specific water quality of the raw water is as follows: COD concentration is 390~890mg / L, BOD 5 The concentration is 90~330mg / L, NH 3 -N concentration is 35~135mg / L, TN concentration is 47~140mg / L, TP concentration is 4.9~15.0mg / L, pH is 6.7~8.0, SS concentration is <1200mg / L. The inoculated sludge is the surplus sludge of the sewage treatment plant and the activated sludge in the biological process oxidation ditch. The sludge return ratio is 200%, and the mixed liquor return ratio is 200%.

[0032] The sampling, storage and analysis methods of effluent water quality are analyzed in accordance with the analysis method of urban miscellaneous water standard water quality items specified in "GBT18920-2002 Urban Wastewater Reclamation and Utilization Urban Miscellaneous Water Quality": System effluent BOD 5 The average ...

Abstract

The invention relates to ship reclaimed water treatment and recycling integrated equipment which comprises a water tank, and a raw water adjusting tank, a hydrolysis oxidation tank, an anaerobic tank,an anoxic tank, an aerobic tank, an air floatation tank, a membrane separation tank, a UV disinfection tank and a reclaimed water adjusting tank which are communicated with one another are sequentially arranged in the water tank in the direction from water inlet to water outlet. The ship reclaimed water treatment and recycling integrated equipment is simple in structure, domestic drainage of a ship is recycled, various domestic drainage of crews is treated into reclaimed water, the equipment is applied to daily water (undrinkable water such as toilet flushing), deck flushing of the ship and the like, and economic benefits are improved.

Description

Technical field [0001] The invention relates to an integrated equipment for treatment and reuse of water in ships and a working method thereof. Background technique [0002] With the continuous changes and development of inland shipping and ocean shipping, ship pollution has become more and more serious. The main pollutants polluted by inland rivers and ports are oily sewage, domestic sewage and ship garbage. The domestic sewage discharged by ships will cause many harms to the surrounding water environment and residents. Therefore, the treatment of ship sewage has become one of the urgent problems to be solved in water pollution. Domestic research on integrated sewage treatment for ships is still relatively backward, and there are many shortcomings such as difficulty in manual operation, low automation, high operating costs, and low resource utilization. Summary of the invention [0003] In view of the shortcomings of the prior art, the technical problem to be solved by the pres...
