Abstract

The utility model discloses an integrated sedimentation disinfection pool, belonging to sewage processing technique, while the clean water area near the traditional two-time sedimentation tank water collection slot is provided with a disinfectant feed tube. According to the structures of the sedimentation tank and the kinds of the disinfectant, the time from flowing water through the disinfectant feed tube and entering into the water collection slot is 2 to 60min, to complete sedimentation and disinfection of the output water of biochemical ponds in one pool. The integrated sedimentation disinfection pool has small volume and reduced investment, having wide application in city sewage and industrial sewage processing engineering.

Description

Integrated precipitation sterilization pool

Technical field:

The utility model relates to a kind of urban sewage purification treatment unit, is to be used for precipitation to remove the sewage suspended substance and finish the integrated precipitation sterilization pool of disinfectant.

Background technology:

At present, in China's urban sewage treatment process, generally all to set up independently secondary sedimentation basins and disinfecting tank.Secondary sedimentation basins is used to remove suspended sludge and impurity, and disinfecting tank is used for kill bacteria and pathogenic bacteria.Disinfecting tank is generally plug flow reactor, and the reaction times got 30 minutes.The secondary sedimentation basins hydraulic detention time was got 2～5 hours, and radical sedimentation basin and horizontal sedimentation tank are near the clarification of water exit end part water quality, and fluidised form is for passing stream.Adopt the mode that disinfecting tank independently is set, not only floor space is big but also increased energy consumption and construction investment, makes the cost increase of sewage disposal.

Summary of the invention:

The floor space that independent setting secondary sedimentation basins and disinfecting tank bring in the existing urban sewage treatment process is big in order to overcome, energy consumption and the big deficiency of construction investment, the utility model provides a kind of have simultaneously settling tank and sterilization pool function, and floor space is little, the integrated precipitation sterilization pool of energy consumption and less investment.

The technical scheme that its technical problem that solves the utility model adopts is: the precipitation sterilization pool comprises flat flow, radial-flow, vertical-flow, and it comprises the water side, and the water side is provided with clear water zone, at clear water zone sterilizing agent is set and adds pipe.

Sterilizing agent adds pipe and comprises that sterilizing agent adds main and sterilizing agent adds arm.

The sterilizing agent of flat flow precipitation sterilization pool adds pipe and is horizontally disposed with.

The sterilizing agent of radial-flow type sedimentation sterilization pool adds pipe and comprises that sterilizing agent adds main and sterilizing agent adds arm, and sterilizing agent adds the arm threeway and vertically is connected on sterilizing agent and adds on the main.Sterilizing agent adds ring-like being arranged on of main and precipitates in the sterilization pool.

The beneficial effects of the utility model are: integrate settling tank and sterilization pool, floor space is little, has reduced energy consumption and investment.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the sectional view of the utility model flat flow structure;

Fig. 2 is the I-I sectional view among Fig. 1;

Fig. 3 is the sectional view of the utility model radial-flow structure;

Fig. 4 is the vertical view of the utility model radial-flow structure.

Embodiment:

Embodiment 1:

As shown in Figure 1, present embodiment is the structure of the integrated precipitation sterilization pool of flat flow, and the length that sterilizing agent adds pipe is set to 30 minutes length of horizontal flow, if the horizontal flow velocity of settling tank is v, the contact sterilizing time is t, and then sterilizing agent adds the length L=v.t of pipe, and wherein t is 30 minutes.Its mechanism is such, and the biochemistry pool water outlet at first enters inlet flume 1, through rectification orifice plate 11, enters settling tank 8, and along continuous straight runs flows then, and suspended sludge is able to the sedimentation removal in this course.The mud that settles down is collected in the sludge bucket 9 by mud scraper 4.Sewage adds pipe 5 through sterilizing agent in the horizontal flow process.The clarification relatively of current this moment.Current add pipe 5 backs through sterilizing agent and entered effluent trough 6 in about 30 minutes.As shown in Figure 2, sterilizing agent adds after pipe 5 passes settling tank body of wall 7, is divided into two up and down, and the other end all withstands on the settling tank body of wall 10.Sterilizing agent adds pipe for perforated pipe, and two with effective settling height trisection up and down.

Effluent trough 6 effusive water are precipitation sterilization back water, can directly discharge.

Embodiment 2:

As shown in Figure 3, present embodiment is the structure of the integrated precipitation sterilization pool of the utility model radial-flow, for radical sedimentation basin:

L＝D-d＝2v.t

Wherein: D-settling tank diameter;

D-sterilizing agent is set add pipe place diameter;

V-horizontal the flow velocity of settling tank edge;

$v=\frac{D}{\mathrm{\πDh}}$

Q-settling tank is handled the water yield;

H-settling region virtual height;

Wherein t=30 minute.

The biochemistry pool water outlet is by water inlet pipe 1 pipe core 2 of upwards flowing through, and enters the precipitation sterilization pool after passing perforation plate.Radial then along continuous straight runs flows, and precipitating sludge is collected the bottom funnel by mud scraper 4, is sent by shore pipe 16 then.In the current horizontal flow process, add arm 15, the clarification of water quality this moment through sterilizing agent.After this about 30 minutes, current entered effluent trough 6, were drained by rising pipe 12.Sterilizing agent adds arm 15 and vertically is connected on sterilizing agent by threeway and adds on the main 13.After sterilizing agent adds that main 13 is through walls and enters the precipitation sterilization pool, ring-like being arranged on the bracing frame 14.

Rising pipe 6 effusive water are precipitation sterilization back water, can directly discharge.

For vertical sedimentation basin, L is that medicament adds the height of pipe apart from the water surface:

L＝v.t

Wherein: v-current upflow velocity;

T-contact sterilizing time, 30 minutes.
