Embodiment 1

[0020] A sewage comprehensive treatment system, the urban domestic sewage comprehensive treatment system includes: a flow regulating tank, a scum removal device, a pressure-resistant filter device, an immersion filter tank, a backwash filter device and a sludge dewaterer;

[0021] The scum removal device receives sewage from the flow control tank and injects microbubbles to float and remove floating pollutants contained in the sewage;

[0022] Filter the sewage from which floating pollutants have been removed through a pressure-resistant filter device to obtain clean water, and dehydrate the sludge collected during the treatment process through the sludge dewaterer;

[0023] The pressure-resistant filter device is backwashed by the backwash filter device, and the backwash waste water discharged from the backwash pressure-resistant filter device is returned to the flow regulator after being filtered by at least the submerged filter tank; There is a porous substrate modified by ...

Abstract

The invention provides a comprehensive sewage treatment system. The comprehensive treatment system for urban sewage comprises a flow adjusting tank, a scum removing device, a pressure-resistant filterdevice, an immersion type filter pond, a backwashing and filter device and a sludge dehydrater; the scum removing device receives sewage from the flow control tank and injects micro-bubbles to floatand remove floating pollutants in the sewage; and the pressure-resistant filter device filters the sewage without the floating pollutants to obtain pure water, and sludge collected in the treatment process is dehydrated by the sludge dehydrater. Under the condition that microbiological treatment is not required, the sewage can be directly filtered, heavy metal is adsorbed by polydopamine, the efficiency of conversion of solar energy into heat energy can be improved, thus, filtered water is further purified, and energy-saving and environmentally friendly comprehensive treatment for urban sewageis implemented.

Description

technical field [0001] The invention relates to a sewage comprehensive treatment system, in particular to a comprehensive urban domestic sewage treatment system. Background technique [0002] Sewage or urban domestic sewage is mainly composed of scum, organic matter, heavy metal inorganic matter and some chemical products. Among them, organic substances mainly include sugar-containing substances, oils and some proteins, etc., heavy metal inorganic substances mainly include sodium chloride, iron ions and calcium ions, etc. Chemical products mainly contain nitrogen and phosphorus, which can cause pollution to the environment Chemical products, the above-mentioned pollution components intersect with each other, bringing very serious pollution to water sources, affecting the work and life of residents, and bringing great inconvenience to people's lives. It can not only eutrophicate the water body, but also cause nitrogen and phosphorus pollution to the water, leading to the eme...
