Abstract

The utility model discloses a resident sewage treatment system, promote unit, flocculation and precipitation pond, the pond of hydrolysising, the biochemical pond of AAO, two heavy ponds, contact oxidation tank, inclined lamellar precipitation pond, filter unit and disinfection pond including the grid that connects gradually. The utility model discloses an each stage will be defiled the water pollutant and carried out all -round elimination, improve the rate of recovery of sewage.

Description

A kind of resident living Sewage treatment systems

Technical field

The utility model relates to sewage treatment area, specifically a kind of resident living Sewage treatment systems.

Background technology

The shortage of water resources is more and more serious, and so, a lot of country of the world also faces same problem, has had a strong impact on daily life and expanding economy in China.In daily life, household water is many especially, thus how processes the sewage of family, waste water and recycles, cause the attention of each side, also poured into the painstaking effort of a lot of technician.Be generally by the sterilization that carries out disinfection again after sewage collecting sedimentation and filtration, reach the object of recycling, but in the sewage of this mode process or containing a lot of objectionable impurities, cannot recycle.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of resident living Sewage treatment systems, by each stage, dirty water pollutant is carried out comprehensive elimination, improves the rate of recovery of sewage.

The technical solution of the utility model is:

A kind of resident living Sewage treatment systems, includes the grid lift unit, flocculation sedimentation tank, hydrolytic tank, A/A/O biochemistry pool, second pond, contact-oxidation pool, inclined-plate clarifying basin, filtering unit and the sterilization pool that connect successively; Described grid lift unit includes the grid and Boosting pumping station that arrange in turn; Described A/A/O biochemistry pool includes anaerobic pond, anoxic pond and Aerobic Pond; Described contact-oxidation pool is connected with blast aeration machine.

The feed-water end of described grid is provided with front pH value tester, and the water side of Boosting pumping station is provided with rear pH value tester, and the water side of described Boosting pumping station is connected with equalizing tank.

Described resident living Sewage treatment systems also includes carbon source throwing device, and carbon source throwing device adds carbon source in anoxic pond.

Described resident living Sewage treatment systems also include arrange in turn sludge storage pool, excess sludge pond and sludge dewatering equipment, described flocculation sedimentation tank is all connected with sludge storage pool with the sludge outlet of inclined-plate clarifying basin, the mud relief outlet of the sludge outlet bottom described sludge storage pool, hydrolytic tank and the sludge outlet of second pond are all connected with excess sludge pond, and the relief outlet in excess sludge pond is connected with the import of sludge dewatering equipment.

Advantage of the present utility model:

The floating matter that the utility model is removed by grid lift unit, the small organic molecule that flocculation sedimentation tank forms flocs unit, the larger molecular organics of difficult degradation is degraded to easily biochemistry by hydrolytic tank, thus be conducive to subsequent biochemical process; In A/A/O biochemistry pool of the present utility model, anaerobic pond by the Phosphurus release in returned sluge, anoxic pond will intake in NO 3 -and nitrate denitrification becomes nitrogen in phegma, Aerobic Pond is by majority of organic pollutants degraded in sewage, by the phosphorus in nitrated for ammonia nitrogen in sewage one-tenth nitrite and nitrate, active sludge excessively absorption effluent, Biochemical Treatment is good, eliminates most objectionable impurities in sewage.One-piece construction of the present utility model is simple, and it is convenient to implement, and stable effluent quality is up to standard.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

See Fig. 1, a kind of resident living Sewage treatment systems, include the grid lift unit 1, flocculation sedimentation tank 2, hydrolytic tank 3, A/A/O biochemistry pool 4, second pond 5, contact-oxidation pool 6, inclined-plate clarifying basin 7, filtering unit 8 and the sterilization pool 9 that connect successively; Grid lift unit includes the grid and Boosting pumping station that arrange in turn, and the feed-water end of grid is provided with front pH value tester, and the water side of Boosting pumping station is provided with rear pH value tester, and the water side of Boosting pumping station is connected with equalizing tank 10; A/A/O biochemistry pool 4 includes anaerobic pond, anoxic pond and Aerobic Pond, and carbon source throwing device 11 adds carbon source in anoxic pond; Contact-oxidation pool 6 is connected with blast aeration machine 12;

Wherein, flocculation sedimentation tank 2 is all connected with sludge storage pool 13 with the sludge outlet of inclined-plate clarifying basin 7, the mud relief outlet of the sludge outlet bottom sludge storage pool 13, hydrolytic tank 3 and the sludge outlet of second pond 5 are all connected with excess sludge pond 14, and the relief outlet in excess sludge pond 14 is connected with the import of sludge dewatering equipment 15.

Principle of work of the present utility model:

First sanitary sewage enters grid lift unit 1, if the water inlet PH that front pH value tester detects is acid, add before grid process sodium hydroxide solution carry out in and regulate, after the floating matter that grid is removed, enter the suction well of Boosting pumping station, sewage enters flocculation sedimentation tank 2 after being promoted by lift pump, if the water inlet PH that rear pH value tester detects can not reach desired effect, the water outlet of lift pump is switched to equalizing tank; Sewage to mix with aluminium chlorohydroxide at flocculation sedimentation tank 2 and forms flocs unit, then carries out precipitation mud-water separation; The supernatant liquor of flocculation sedimentation tank 2 enters hydrolytic tank 3, and in waste water, the larger molecular organics of difficult degradation is degraded to easily biochemical small organic molecule; The water outlet of hydrolytic tank 3 enters in A/A/O biochemistry pool 4, at anaerobic pond by the Phosphurus release in returned sluge, and NO in intaking in anoxic pond 3 -and nitrate denitrification becomes nitrogen in phegma, in Aerobic Pond by majority of organic pollutants degraded in sewage, by the phosphorus in nitrated for ammonia nitrogen in sewage one-tenth nitrite and nitrate, active sludge excessively absorption effluent, consider that the denitrifying carbon source of possibility biochemical treatment unit is not enough, carbon source throwing device 11 is set, if carbon source is not enough in operational process, in anoxic pond, add carbon source; A/A/O biochemistry pool 4 water outlet enters second pond 5 and carries out mud-water separation, returned sluge is promoted to A/A/O biochemistry pool 4 front end, excess sludge is promoted to excess sludge pond 14, second pond 5 supernatant liquor enters contact-oxidation pool 6, blast aeration in pond, removes the pollutents such as dirty organic pollutants, ammonia nitrogen, total nitrogen further by microorganism on filler; The water outlet of contact-oxidation pool 6 enters inclined-plate clarifying basin 7, removes flco and suspended substance; The water outlet of inclined-plate clarifying basin 7 enters filtering unit 8, removes suspended substance and nitrogen phosphorus substance in sewage further; The water outlet of filtering unit 8 enters sterilization pool 9 and carries out disinfection, and adds dioxide peroxide and carry out disinfection in sterilization pool, qualified discharge after sterilization.
