Sewage ecological treatment system

Abstract

The invention discloses a sewage ecological treatment system. The system comprises a discharge tank, an oil separation tank, an ecological treatment tank and a disinfection tank which are sequentiallyconnected through pipelines, the top of the oil separation tank is sealed, and an access hole is formed in the top of the oil separation tank; a movable sealing cover is mounted at the access hole; an inner cavity of the oil separation tank is sequentially divided into a filter residue area, a first-stage oil filtering area, a second-stage oil filtering area and a water outlet area; the filter residue area is connected with the discharge tank; the water outlet area is connected with the ecological treatment tank, a sewage discharge tank is arranged on one side of the oil separation tank, a sludge outlet pipe communicated with the sewage discharge tank is arranged at the bottom of the side of the oil separation tank close to the filter residue area, oil scrapers are installed on the oil separation tank sealing tops on the top sides of the first-stage oil filtering area and the second-stage oil filtering area, and oil outlets of the oil scrapers are located over the sewage discharge tank. According to the system, pretreatment or separation can be carried out on greasy dirt impurities in industrial wastewater, the purification load of a downstream ecological vegetation layer is reduced, the whole system can carry out self-purification under the condition that no specially-assigned person is needed for watching, and a better purification treatment effect is obtained.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage ecological treatment system. Background technique [0002] The sewage ecological treatment system can meet the treatment of urban domestic sewage, organic industrial sewage, animal husbandry wastewater and hospital sewage, but the treatment methods for each sewage are different. Sewage in industrial places often contains oil and large particles of insoluble substances, and the purification effect of general purification systems is often not very good, especially the oily impurities in it will not only affect the degradation and absorption of the ecological vegetation layer, but in severe cases will affect the ecological vegetation For the normal growth of the layer, another special person needs to be hired for long-term care and care, which increases the treatment cost and cannot obtain a better purification treatment effect.
