Description
Technical field
The utility model relates to the pH value monitoring device of waste water, more belongs to the PH on-Line Monitor Device in the biological denitrification system.
Background technology
Most wastewater denitrification system monitoring pH values have three kinds of methods: (1), pH value automatic on-line instrument.The shortcoming of this method is that instrument involves great expense, Maintenance and Repair cost height, and the monitoring point is few, can not normally reflect truth in the bio-reactor.(2), wide pH value value test paper.The shortcoming of this method is that measuring error is big, can only mechanical reflection solution acid alkalinity, the operation debugging of accurate guidance system in this way.(3), portable pH value measuring instrument.This method accuracy is higher, but labour intensity is bigger, and efficiency is low, and operating personnel contact the biological tank toxic and harmful for a long time, and health is damaged.
Because survey the reason of pH value difficulty, many waste water processing stations adopt and add Na
2CO
3Method overcome contradiction.But add Na
2CO
3Following unfavorable factor is arranged: 1, solution device, medicine storage device floor area are big, and investment is big; Na
2CO
3Easily crystallization, the operational management inconvenience.2, Na
2CO
3Market price fluctuation is big, and the supply and demand fluctuation is big, and buying sometimes is difficult for, and causes the medicament shortage, produces to be difficult to the dimension meter.3, Na
2CO
3Be pockaged powder, logistics cost and add the cost of labor height.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of labour intensity low, reduce harmful, toxic gas is simple, durable to injury, the apparatus structure of human body, monitoring result truly, pH online auto monitoring device accurately.
Realize the technical measures of above-mentioned purpose:
Novel PH on-Line Monitor Device in the biological denitrification system comprises biological reaction pool, detector, sludge concentration tank, and it is: insert a siphonal end in biological reaction pool, its other end is connected with the bottom of monitoring container; Be connected with an end of discharging tube on the top of monitoring container, the other end of discharging tube inserts in the sludge concentration tank; Detector is inserted the monitoring container, and the reader of its detector places outside the monitoring container by signal wire.
It is: siphonal firm frame is housed in biological reaction pool.
It is: described firm frame is made up of support bar, the pole that is connected with support bar, the fixture that is connected with pole, and fixture is fixed U trap.
It is: sample valve and backwash valve are housed on U trap.
It is: U trap all is equipped with at the waste water inflow point in biological reaction pool, stage casing and wastewater outlet place, and the monitoring container that matches with U trap and interior detector thereof, the reader, discharging tube, the sample valve that is equipped with on U trap and the backwash valve that are connected by signal wire with detector.
The utility model compared with prior art, its characteristics:
(1), significantly reduce the injury of labour intensity, the minimizing venomous injurant confrontation person, improve laborer's working environment;
(2), more accurate to the pH value variation monitoring in the bio-reactor, the pH value is controlled at reasonably accurately in the scope, significantly reduce alkaline consumption, make the biological denitrification system operation more economically, for enterprise reduces cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Be described in detail below in conjunction with accompanying drawing:
Novel PH on-Line Monitor Device in the biological denitrification system comprises biological reaction pool 1, detector 2 and goes up reader 7, the sludge concentration tank 3 that connects by signal wire 8.It inserts an end of U trap 4 in biological reaction pool 1, the other end of U trap 4 is welded to connect with the bottom of monitoring container 5; On U trap 4 and sample valve 13 and backwash valve 14 be housed; At an end of the welding of the top of monitoring container 5 and the discharging tube 6 that communicates, the other end of discharging tube 6 inserts in the sludge concentration tank 3; Detector 2 is inserted monitoring container 5, and the reader 7 on its detector 2 places outside the monitoring container 5 by signal wire 8.
In order to make U trap 4 firm, to guarantee stability, accuracy and the representativeness of monitoring result, firm frame 9 of U trap 4 is housed in biological reaction pool 1 for it and U trap 4 all is equipped with at waste water inflow point, stage casing and wastewater outlet place biological reaction pool 1 in, the reader 7, discharging tube 6, the sample valve 13 that is equipped with on U trap 4 and the backwash valve 14 that reach the monitoring container 5 that matches with U trap 4 and interior detector 2 thereof, be connected by signal wire 8 with detector 2.
The formation of firm frame 9:
Its by the support bar 10 of fixedlying connected with the wall of biological reaction pool 1, with support bar 10 welding or bolted pole 11, with pole 11 whole processing or the annulus that are welded to connect be that formula or pawl formula fixture 12 are formed, be fixed in the fixture 12 with U trap 4 employing screw threads or fit system or with claw or nut.Fixture 12 also can be the firm U trap 4 of balancing weight mode.
