Description

Intelligent equipment for adding water treatment medicines

Technical Field

The utility model relates to the technical field of water treatment, in particular to intelligent equipment for adding water treatment medicines.

Background

Coagulant and flocculant are widely used in water treatment links of industrial and domestic water to achieve the purpose of accelerating separation of suspended solid impurities in water. Wherein the coagulant neutralizes the surface charge (commonly negative charge) of the suspended fine particles by the counter charge (commonly positive charge) contained therein, so that the particles can overcome the strong repulsive force between the same type of charges, thereby coagulating into larger particles. The flocculant has the main function of linking the formed solid large particles into giant floccules by using a long-chain structure of the high polymer organic matters, so that the giant floccules can move downwards or upwards in a unidirectional way under the action of gravity or the upward buoyancy of bubbles, and the purpose of rapidly separating the giant floccules from a water body is achieved. The flocculants used in conjunction with coagulants are often anionic (negatively charged), but there are also cases where cationic (positively charged) or nonionic (uncharged) flocculants are used. Sometimes the flocculant can be used alone without the coagulant;

there are some devices that regulate the amount of chemicals by monitoring the water quality. Known techniques include:

1. and detecting the water inlet turbidity of the water treatment equipment to adjust the dosage of the chemicals. If turbidity increases, the control device increases the amounts of coagulant and flocculant in the same ratio according to a preset program.

Vice versa;

however, the procedure cannot separate the effect of each of the coagulant and flocculant due to the single parameter of water turbidity, and thus cannot be independently adjusted for both chemicals. In practical applications, the dosing ratio of these two drugs is often a fixed value. When the parameters such as the size of the fine particles entering the water, the surface charge intensity and the like are changed, the dosages of the coagulant and the flocculant are required to be independently adjusted according to the change of the water quality so as to achieve the optimal treatment effect by using the least dosage. Fixing the ratio of the two medicines can lead to the problem of medicine waste and poor water treatment effect. Secondly, the existing method cannot reflect the actual water treatment effect, and another device is often needed to monitor the turbidity of the effluent. In addition, the measurement of the existing method is greatly affected by bubbles in water, and the method is not applicable to the dosage control of air floatation equipment. Finally, as the inlet water contains more impurities, the equipment is easy to block a water inlet pipeline, and the problems of larger measurement deviation and the like caused by the deposition of solid particles on a turbidity meter probe are solved, so that the effect is poor in practical application;

2. another common scheme controls dosing by monitoring effluent turbidity. If the turbidity of the effluent increases, the amounts of coagulant and flocculant are increased in the same proportion. Vice versa;

the same problem exists in this solution as in the above solution, namely that the independent adjustment of the coagulant and flocculant cannot be performed with respect to the changes in the size of the incoming water particles or the intensity of the surface charge using a single parameter such as turbidity, resulting in waste of chemicals and poor water treatment effect. Moreover, this solution has serious delay problems, especially in sedimentation tanks, due to the residence time in the water treatment plant, often requiring several hours from the dose adjustment to the effect. This may lead to long treatment times and large deviations from the target.

Therefore, we propose a water treatment drug adding intelligent device.

s1, if a water sample tank 13 is used, ensuring that the water sample in the water inlet tank is consistent with the water sample in the water inlet pipeline of the water treatment equipment. This requires that the water inlet be kept open and that the water sample flow rate be such that it is uniform.

The method is applied to the scene of removing suspended particles in the water body in a sedimentation or air floatation mode by using one or a coagulant and a flocculant in water treatment. Common fields include clarification sections of domestic water treatment plants, domestic and industrial sewage treatment plants, mineral flotation processes, paper mill air flotation white water fiber recovery processes, and the like.

In this scheme, utilize sediment air supporting room 1 to simulate water treatment facilities's working process accurately. It takes the incoming water sample mixed with coagulant and flocculant from the water intake pipe of the water treatment apparatus and let it stand in the sedimentation air flotation chamber 1 for a period of time (typically 5-10 minutes). During this time, the solids in the water will either sink to the bottom by gravity or rise to the top by dissolved bubbles. A turbidity meter probe is arranged in the middle of the sedimentation air floatation chamber 1, and can continuously measure the turbidity of the water body with medium height. The rate of turbidity decrease with time of rest may reflect the effect of the flocculant, while the final turbidity in a long-term rest water sample reflects the effect of the coagulant addition. The principle is as follows:

coagulant: the primary function of the coagulant is to neutralize the negative charge on the surface of the fine particles so that they can agglomerate together to form larger particles. Accelerating their sedimentation or air-floating speed in water body. Otherwise, the repulsive forces of the same charge will cause the fine particles to be suspended in the body of water for a very long time (which may be as long as several days or even longer). If the coagulant is used in an appropriate amount, large particles can settle or be carried up the water surface by the bubbles in a relatively short period of time (typically less than 20-30 minutes) even without the flocculant.

The apparatus determines the coagulation acceleration effect by measuring the turbidity of the water body at a level which is left for a sufficient period of time (usually 5-10 minutes) and compares it with a preset value. The preset value is often determined by the water quality requirements of the water exiting the water treatment device. If the turbidity is higher than the water quality requirement, the coagulant is insufficient, and a large amount of fine particles still cannot be settled or air-floated in the water body, so that a plurality of coagulants are needed. If turbidity is lower than the effluent requirement, this indicates that the setting accelerator is too good, there is room for reducing the setting accelerator to save on setting accelerator costs.

Flocculant: the main function of the flocculant is to agglomerate the solid large particles formed by the coagulant, and accelerate the sinking or air floatation speed. If the flocculant is used in an appropriate amount, the flocculant is larger in volume and higher in density, and the strength of the flocculant against detour is also larger, so that the flocculant is concentrated at the bottom (sediment) or the water surface (air floatation) in a shorter time. If the dosage is insufficient, the floccule is small in volume, low in density and strength, and the sedimentation or floating can be completed for a longer time. The appropriateness of the flocculant dosage can be evaluated by monitoring the time for the water sample in the middle part of the sedimentation air floatation chamber 1 to reach acceptable turbidity and comparing the time parameter with the time parameter required by water treatment equipment. If the middle part of the water sample reaches the preset turbidity for longer than the expected time, the flocculation effect is poor, and the dosage of the flocculant needs to be increased. Otherwise, if the time for reaching the preset turbidity in the middle of the water sample is shorter than the expected time, the flocculation effect is too good, and the flocculant consumption is reduced in space, so that the aim of saving the cost is fulfilled.

The utility model uses equipment to simulate the solid-liquid separation process of sedimentation and air flotation, and achieves the prejudgment of clarification effect by observing the change condition of the turbidity of the water body along with time, and realizes independent and accurate control of the coagulant and the flocculant according to the final turbidity and the change speed of the turbidity. The test sample is taken from a water sample that already contains all chemicals to be introduced into the sedimentation or flotation cell, thus ensuring the closest prediction of the actual situation of the system. Because the sampling point is very close to the dosing point, the adjustment of dosing amount can be timely fed back to the test result, and the minimum delay is ensured. In addition, the design of sedimentation and air floatation chambers ensures that the monitoring equipment cannot be blocked by a water inlet pipeline.

The scheme aims at the problem that in the prior art, only the single parameter of water inlet or water outlet turbidity is measured, and the specific medicine adding amount can not be judged and needs to be adjusted. It is often necessary to fix the addition ratio of these two medicines. This does not accommodate the diversity of incoming water quality variations. Resulting in a control device that does not maintain optimal treatment results and the most reasonable amounts of drug to be added.

According to the utility model, the turbidity meter is used for observing the change speed and the final turbidity of the water sample in the sedimentation or air flotation process, so that the functions of the coagulant and the flocculant are effectively distinguished, and the two medicines can be accurately controlled respectively. The adaptability of the device to diversified water inflow is effectively guaranteed, and the effect of reducing the solid content in water is greatly improved. And reduces the waste of medicines. In addition, through carrying out sedimentation air-float simulation to the water, the technology can rapidly and accurately pre-judge the separation condition of solid contents in water treatment equipment, so that the dosage can be reliably and timely adjusted independently, and the stability of the solid-liquid separation effect is ensured.
