Garbage power defoamer-the end of water treatment foam
Garbage is one of the sources of pollution in our daily life. With the improvement of people's living standards, take-out and fast food are now very developed, and the convenience of life has also caused a very big burden to our environment. In the process of garbage disposal, often encounter the problem of foam, for the foam generated in the garbage, you can choose the garbage power defoamer to eliminate.
The most important ways of waste disposal are sanitary landfill and incineration for power generation, and waste incineration plants are now basically capable of achieving zero waste water and waste gas emissions from waste incineration. However, the characteristics of waste are complex and variable, and pollution may be generated in all aspects from collection and transportation to treatment and utilization, so that waste itself is an important source of pollution. Waste leachate treatment is one of the important environmental.
In the waste leachate CODcr, BOD5 concentration can reach thousands to tens of thousands, higher than the usual concentration of sewage, a large number of bubbles is not conducive to the discharge of gas, but also lead to substandard, can not enter the city's pipeline. That how to choose a high-quality waste leachate water treatment antifoaming agent is another technical work, choose the wrong, will lead to damage to the DTRO membrane, can not achieve the effect of defoaming, the loss is not worth it.
Waste leachate produced in waste incineration is biochemical treatment process using activated sludge method in order to effectively control the degradation of high concentration of organic pollutants in leachate, but aerobic pool aeration will produce a large amount of foam, sludge and biological foam from the aerobic pool gushing out, causing serious corrosion of external equipment, damage and extensive pollution of the pool wall, causing serious adverse effects on the surrounding environment, so it is necessary to add waste leachate defoamer to control.
The waste leachate power defoamer developed for landfill, sewage and leachate treatment is composed of polyether, silica, dispersant and stabilizer, etc. It has good defoaming and foam inhibition effect, and the defoamer can still keep defoaming under the harsh conditions of high temperature, strong acid and alkali, and will not affect the MBR membrane system, will not cause blocking of the membrane, and will not affect the strains of bacteria in the leachate, specially developed defoamer for all kinds of biological water recycling treatment systems.
Garbage power generation defoamer is put into use in the following way.
1. Pump add: use pump to add continuously, defoamer can be added after dilution or added directly.
2. Manually add: pump add insufficient foam inhibition performance, foam is too high, you can add the defoamer directly.
3. Adding amount: according to the defoamer performance and foaming capacity is generally tens to hundreds of ppm.
