Embodiment 1

[0030] like figure 1 As shown in the figure, the inlet water enters the inclined tube sedimentation tank 6 after adding coagulant, passes through the spoiler stone 7, the water inlet baffle 8, and the inclined tube 9, and after sedimentation, the water is discharged from the perforated sump 10, and enters the aerated biological zeolite filter column countercurrently. 12 The water inlet area of ​​the lower layer, after mixing with the gas, enters the coarse zeolite support layer 14 and the granular zeolite layer 15 successively from the long handle filter head 13, and the effluent freely falls to the activated carbon filter column 18, and flows downward through the granular activated carbon 19, quartz The sand supporting layer 20 and the long handle filter head 13 are discharged to the water tank 22. The front end of the water inlet area of ​​the inclined tube sedimentation tank 6 is provided with a 200-300mm spoiler stone 7 and a water inlet baffle 8 . The filler of the aerat...

Embodiment 2

[0033] When backwashing the aerated biological zeolite filter column, close the first valve 2, the second valve 11, the fourth valve 17, and the eighth valve 33; open the third valve 16, the seventh valve 31, and the tenth valve 36; close the dosing Metering pump 3 and integrated ClO 2 Generator 29; run the backwash water pump 32, adjust the aeration rate of the blower 26, control the air-water ratio of backwash, and the backwash waste water is discharged from the backwash waste liquid pipe 37. After the recoil is finished, close the backwash water pump 32, the seventh valve 31, the backwash water inlet pipe 35, and the tenth valve 36, and open the first valve 2, the second valve 11, the fourth valve 17, the dosing metering pump 3 and the integrated Formula ClO 2 The generator 29 restores the water production process.

Embodiment 3

[0035] When backwashing the activated carbon filter column, close the sixth valve 24, the water tank 22, and the ninth valve 34; open the fourth valve 17, the fifth valve 21, the seventh valve 31, the eighth valve 33, and the tenth valve 36; close the integrated ClO 2 Generator 29; run the backwash water pump 32, and the backwash waste water is discharged from the backwash waste liquid pipe 37. After the recoil finishes, close the backwash water pump 32 and the seventh valve 31, the eighth valve 33, the tenth valve 36, open the water tank 22 and the integrated ClO 2 The generator 29 restores the water production process.

Abstract

The invention relates to a combined set for treating a micro-polluted source water in counties and towns, and the combined set comprises an inclined tube sedimentation tank, an aeration biozeolite filter column and an activated carbon filter column, wherein the inclined tube sedimentation tank consists of a water inlet region, a sloped tube region and a water collection region, the water inlet region is provided with turbulent stones and a baffle, the water collection region discharges water through a perforated water collection tank, the aeration biozeolite filter column consists of a water/gas inlet region, a filter material region and a water collection region, aeration is carried out in a blast aeration mode, gas is mixed in the water inlet region and enters the filter material region through a long-handle filter head, the filter material consists of coarse-grain zeolite and common-grain zeolite, the effluent water of the aeration biozeolite filter column enters the activated carbon column in a hydraulic drop mode, and the activated carbon filter column consists of a filter material region and a water outlet region. The inclined tube sedimentation tank water inlet region is provided with the turbulent stones and baffle to enhance the flocculation effect of the coagulant and the removal effect of the sedimentation tank. The activated carbon filter column connected to the aeration biozeolite filter column performs a two-stage biochemical synergistic action, and implements advantage complementation, thereby enhancing the water quality of the effluent water and lowering the treatment cost. The combined set can effectively remove ammonia nitrogen, organic substances, manganese and other pollutants in the micro-polluted source water, has the advantages of compact technical linkage, low investment and operating cost and stable quality of effluent water, and is suitable for being used in small-scale water generation occasions, such as water supply to counties and towns.

Description

technical field [0001] The invention belongs to the technical field of drinking water treatment, and in particular relates to a combined device for treating micro-polluted source water in counties and towns. Background technique [0002] Due to the increase in population and the rapid development of industry, surface water is often polluted to varying degrees, and indicators such as smell, ammonia nitrogen, and organic matter generally exceed the standard. With the acceleration of urbanization in my country, the regional water quality deterioration with counties and towns as the core has attracted increasing attention. In small-scale water supply occasions such as counties and towns, the construction of water supply facilities is insufficient, the equipment is outdated, the equipment is aging, the degree of automation is low, the construction of the pipe network is not perfect, and the problem of drinking water safety is becoming increasingly prominent. New technologies and...
