Abstract
The invention relates to an urban sewage treatment process and belongs to the technical field of environment engineering. The process comprises the steps of depositing, active sludge treatment, sterilization and the like. According to the urban sewage treatment process, water is sprayed out in a dry mist mode, and sterilized through ultraviolet rays; the particle size of dry mist is small, the ultraviolet rays can carry out more comprehensive sterilizing, and the effect can completely meet the requirement of GB5749-2006 of the drinking water sanitary standard of the people's republic of China.
Description
Technical field
The present invention relates to a kind of city domestic sewage treatment process, belong to field of environment engineering technology.
Background technology
In existing city domestic sewage treatment process, purifying sewage with activated sludge process is a kind of very ripe scheme, and its cost is low, pollutes little, widely uses.But the sterilization process that the sewage after purification carries out, effect is poor, can not meet the demand of domestic water, can only be used as industrial agricultural water.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of city domestic sewage treatment process of potent sterilization capability.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of city domestic sewage treatment process, comprises the following steps:
(1) sewage is introduced settling tank, precipitate;
(2) clear water on settling tank upper strata is led to aeration tank, purify with activated sludge process;
(3) water fully reacted is introduced second pond, carry out secondary sedimentation;
(4) clear water on second pond upper strata is drawn, to dry fog device;
(5) water smoke sprayed by dry fog device is with ultraviolet disinfection;
(6) condensed water after sterilizing is collected.
Such scheme further improves and is: after step (6), the condensed water collected filtered with reverse osmosis membrane.
Such scheme further improves and is: in step (2), when water temperature is lower, carry out heat treated.
City domestic sewage treatment process provided by the present invention, by water with the ejection of dry fog form, then with ultraviolet disinfection; The particle diameter of dry fog own is less, and ultraviolet can sterilizing more comprehensively, and its effect can meet " People's Republic of China's drinking water sanitary standard " GB5749-2006 requirement completely.
Embodiment
Embodiment
The city domestic sewage treatment process of the present embodiment, comprises the following steps:
(1) sewage is introduced settling tank, precipitate;
(2) clear water on settling tank upper strata is led to aeration tank, purify with activated sludge process;
(3) water fully reacted is introduced second pond, carry out secondary sedimentation;
(4) clear water on second pond upper strata is drawn, to dry fog device;
(5) water smoke sprayed by dry fog device is with ultraviolet disinfection;
(6) condensed water after sterilizing is collected.
If water Minerals salts contg is higher, then, after step (6), the condensed water collected is filtered with reverse osmosis membrane.
In step (2), when water temperature is lower, carry out heat treated.
Of the present inventionly be not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
