Background
Domestic sewage is wastewater discharged in daily life of residents and mainly comes from residential buildings and public buildings, such as houses, institutions, schools, hospitals, shops, public places, industrial enterprise toilets and the like. The pollutants contained in the domestic sewage are mainly organic matters (such as protein, carbohydrate, fat, urea, ammonia nitrogen and the like) and a large amount of pathogenic microorganisms (such as parasitic ova, enteroinfectious viruses and the like). Organic matters existing in domestic sewage are extremely unstable and easily decomposed to generate offensive odor. Bacteria and pathogens propagate in large quantities by taking organic matters in domestic sewage as nutrition, and can cause epidemic of infectious diseases. Therefore, domestic sewage must be treated before being discharged. The conventional □ law vessel □ domestic sewage □ treatment plant cannot meet the emission index requirements of the new regulation passing resolution No. □ MEPC.159 (55). In order to meet the implementation of new regulations, □ research institutions and □ enterprises at home and abroad add a membrane treatment link on the basis of a traditional □ domestic sewage □ treatment device by a □ physical method. This improvement □ doubtlessly addresses the emission standards required by new regulations, but does not adequately address new issues with membrane fouling.
Because of the existence of adhesive □ aggregates such as particles, colloids and micro □ substances in □ activated sludge □, the particles are deposited and adsorbed on the surface □ of the membrane and the inside of the membrane pores after the device is transported for □ □ time, which causes the blockage of the membrane module pores, so that the flux of the membrane is rapidly reduced, the □ efficiency of the device is reduced, and the service life of □ is shortened. The pollution problem of the membrane is solved by adopting □ □ flushing or chemical solution flushing method on the current ship, but the pollution problem has cleaning dead angle, the cleaning is not thorough enough, the recovery rate of membrane flux is low, and the flushing pressure is fixed by □; the □ chemical solution used for washing may affect the activity of micro □ substances and may cause □ times of pollution to □ environments. In order to solve these problems of the current ship □ □ live sewage □ treatment plant, it is necessary to develop □ new □ processes.
