Description
Technical Field
The utility model relates to a penetrant preliminary treatment technical field, concretely relates to add sour mixed defoamer for DTRO handles rubbish penetrant technology.
Background
The landfill leachate is high-concentration organic wastewater with high ammonia nitrogen concentration, serious imbalance of nutrition proportion and low biochemical degradability. With the implementation of the standard for controlling pollution of domestic garbage landfill (GB16889-2008), the standard is difficult to reach by only relying on the traditional biochemical treatment method. The membrane separation technology has the obvious advantages of small influence of raw water quality, stable effluent quality, small occupied area and the like in the field of landfill leachate treatment, and is increasingly widely applied.
In recent years, the DTRO technology has been widely used in the treatment of waste permeate, and this technical scheme is to separate the waste permeate into permeate and concentrate by the separation function of the membrane technology. Wherein the main pollutants such as heavy metal ions, COD, ammonia nitrogen and the like are separated into the concentrated solution, and the pollutants are basically removed from the permeate liquid, thereby meeting the requirements of discharge standards.
The concentrated solution generated in the way is reduced by about seventy percent, and can be recharged to a refuse landfill for digestion treatment. The generated permeate liquid accounts for most of the permeate liquid, meets the requirement of discharge standard, can be directly discharged and even can be recycled. The new process has the advantages of small occupied area, short construction period and stable water outlet, thereby being rapidly popularized.
The garbage penetrating fluid is sewage with high salt content and has high alkalinity and hardness. After the DTRO is concentrated and separated, precipitation and scaling are easy to occur on the membrane, so that the working pressure of a DTRO system is increased, the water yield is reduced, the quality of permeate liquid is reduced, and the normal operation of the DTRO is influenced. Therefore, as a pretreatment of this treatment process, it is necessary to reduce the fouling tendency of the DTRO membrane by adjusting the pH value to a low value by adding an acid and then adding a scale inhibitor.
The garbage penetrating fluid is high-pollution and high-concentration COD sewage, and in the acid adding process, acid and organic pollutants are subjected to chemical reaction to generate a large amount of foams. As shown in figure 1, in the prior art, acid is added into a raw water tank, because an acid adding and mixing device is generally arranged at a water inlet of the raw water tank, sewage added with acid flows into the raw water tank along with foam, and often a large amount of foam overflows from an upper opening until the whole water tank surface is covered. The operator has to wash the outer surface of the raw water tank with water, as a result of which the foam overflows, polluting the surrounding environment and the situation is very bad.
Some companies set a defoaming agent adding system in an acid adding process to eliminate foam, but defoaming agents are generally unfavorable to DTRO membranes, are easy to adhere to the surfaces of membranes and are not easy to remove, and new damage is caused due to membrane fouling. Therefore, a new idea is needed to try to eliminate the foam hazard after adding acid to raw water.
