Does the biogas purification tank use quartz sand filter media?

Hello! The biogas digester does not need to be purified, so there is no need for quartz sand filter material.

KDF is short for Kinetic Degradation Fluxion. KDF55: KDF 55 Medium (50% Cu, 50% Zinc) The effect is:

Chlorine removal, water-soluble heavy metals, control bacteria. KDF55 dechlorination: Zn+HoCl+H2O+2E- Zn2+ +Cl-+H++2OH- KDF55 to remove lead and mercury Zn Cu Zn+PB(NO3)2 Zn Cu Pb + Zn(NO3)2 Zn Cu Zn+HgCl2 Zn Cu Hg+ ZnCl2

If Aihuipu's direct drinking water dispensers can't meet the direct drinking standards, what other water dispensers in the world can do it?! Is there a qualitative difference between the water quality of foreign countries and the water quality of China? If you come to China, you can't adapt to China's water quality?

Is China's water all water with Chinese characteristics? To be disposed of with a domestic garbage water machine?! If it doesn't meet the standard, can Aihuipu be the first in the world?

Could it be that the water in the whole world is only China's water, which Aihuipu can't handle?! NSF standard, is there a domestic brand that can get this mark? No!

Please don't treat Xiao Ai, who is in a monopoly position in the world, like this!

When has tap water been qualified? The Ministry of Health organized local health administrative departments to conduct health and safety sampling inspections on some drinking water chemical treatment agents, drinking water transmission and distribution pipes and water quality processors. Random inspection found that 38 water plants or water companies used substandard water chemical treatment agents, and the unqualified content was mainly excessive heavy metals such as lead and no valid health license approval; The six kinds of water transmission and distribution pipes sampled from the production enterprises were unqualified, and the unqualified content was mainly the excessive amount of soaking and dissolution of harmful substances such as lead and the lack of valid health license approvals.

I haven't heard of a biogas digester having a purification tank. According to the process, the biogas project has pretreatment tank, acidification tank, water collection tank, anaerobic tank, biogas slurry tank, sludge tank and other units. You must be asking about the biogas purification unit, where a desulfurizer is installed on the biogas pipeline.

The difference between a biogas purification tank and an ordinary biogas digester is that the former uses low-purity biogas to produce high-purity biogas. The latter produces low-purity biogas.

The biogas purification tank is a filtration and purification device added to the back end of the discharge room of the biogas digester. Everything else is the same. Such a filtration device is the same as a three-format septic tank.

Quartz sand has no impurities, its compressive and wear-resistant ability is strong, and the mechanical strength is very high, the chemical stability performance is also very good, it has a good ability to intercept dirt, the work efficiency is also very high, and its service life is still very long. It is usually suitable for single and double layer filter tanks, filters, as well as ion exchangers, etc. All of its indicators need to be met (

CJ T44-2006). When processing, refined quartz sand needs to be selected, and acid treatment agents should be used at the same time, while ordinary quartz sand can meet the needs of different users. The most commonly used specifications are:

Millimetre. mm, mm, mm, mm, 16millimeters, etc.

After crushing, it is made of natural quartz ore, which is processed by screening, washing and other processes. Generally, it is the appearance of a polyprism, with a spherical shape, a pure white surface, a high degree of mechanical strength, strong dirt interception ability, and acid resistance.

Quartz sand filter material has no impurities, compressive and wear-resistant, high mechanical strength, stable chemical properties, strong dirt interception ability, high efficiency, long service life, suitable for single-layer and double-layer filter pools, filters and ion exchangers, and all indicators have reached the (CJ T43-2009) standard. Refined quartz sand, pure white quartz sand, acid treatment agent, ordinary quartz sand are processed to meet the needs of different users. Common Specifications:

1-2mm 2-4mm 4-8mm 8-16mm 16-32mm。

It is made of natural quartz ore through crushing, screening, washing and other processes. The appearance is polygonal, spherical, pure white, and has the advantages of high mechanical strength, strong dirt interception ability, and good acid and alkali resistance.

Biogas compression filling in gas tanks is not available for the time being. Biogas is a mixture of gases with methane (CH4) and carbon dioxide (C02) as the main components. Methane accounts for 60 to 70 percent, carbon dioxide for 30 to 40 percent, and the rest for combustible hydrogen, carbon monoxide, hydrogen sulfide, oxygen and nitrogen gases.

The purification of biogas requires the use of a gas separation process to turn carbon dioxide into dry ice for other industrial uses, and then compress the refined combustible gas into a liquefied state. It is theoretically feasible to re-shrink the filling to the cylinder into liquefied gas** for residential use.

But methane is generally not liquefiable at room temperature. The critical temperature of methane is, that is, above this temperature, no matter how much pressure is applied, methane cannot be liquefied. Methane can be compressed above the critical temperature, and the compressed methane is still a gas, not a liquid.

Therefore, it is theoretically feasible to use compressed methane purified by storing gas in cylinders as fuel. The problem is that there are many key factors, such as the value of industrial development, market value, the cost of energy reuse, etc. Therefore, biogas is generally used by gas pipes.

I believe that this series of problems will be solved in the near future.

After biogas desulfurization and other treatments, it can be transported to the gas station for compression, filling or something,,, you don't have to do it yourself! Equipment! It's not that simple.

At the current level of technology, it is not possible to fill.

After the biogas is liquefied, it can be filled into the tank like the liquefied gas that is usually used, but the biogas needs to be liquefied at atmospheric pressure and minus 180, and it needs to be purified and purified before liquefaction, and the process is more complex and needs to be absolutely safe. Therefore, the cost of biogas liquefaction is very high, and it is also prone to leakage, and the technology is not yet mature, and it cannot be filled.

At present, it cannot be canned in China.

The manure and wastewater of the farm are added to the biogas digester for fermentation, which can not only produce gas, but also make organic fertilizer, which can be used for irrigation of crops, flowers, vegetables, fruit trees, etc. Moreover, the use of biogas is a closed and complete agricultural cycle. There should be no non-standard emissions.

The main functions of the biogas digester in the treatment of aquaculture wastewater: First, it reduces the COD content in the wastewater. According to the data, if the fermentation is complete, the removal rate of COD is more than 80%.

Often, the biogas digesters on the farms are discharged before they are fully fermented. Second, the livestock and poultry manure has been harmlessly treated. That is, due to the digester anaerobic digester, harmful germs are completely killed.

If you want to meet the discharge standard, you have to let the livestock and poultry manure fully ferment, and then separate the biogas residue and biogas slurry. Biogas residue can be used as an organic fertilizer. The biogas slurry enters the anti-seepage storage tank for precipitation.

At the end of the anti-seepage storage tank, a biological purification pond is built, and the precipitated biogas slurry can be discharged into the purification pond. Aquatic plants (e.g., water hyacinth, lotus root, etc.) are planted in the pond. Such treatment measures may meet the emission standards.

There is better than no imposition of aerobic treatment.

Theoretically, of course, yes, but there are no projects that have been fully put into production yet, and there should be them in the middle of 16 years, and I know that several projects are in the commissioning or construction stage.

Yes, the following ** can help you.

Starch has an important application in the food industry and industrial production, China's Henan, Anhui production of wheat starch manufacturers are relatively concentrated, and wheat starch production at the same time produces a large amount of wastewater, if the wastewater is not effectively treated directly discharged, will cause serious pollution of the water body. Based on the design and operation of the wastewater treatment and transformation project of a wheat starch plant in Anhui, this paper tries to seek an economical, efficient and resource-based sewage treatment and biogas utilization process for the wheat starch industry to provide a reference for the treatment of wastewater in the wheat starch industry. According to the analysis of wheat starch wastewater water quality and the previous engineering practice experience, on the basis of making full use of the original project, a wastewater treatment process with anaerobic MIC-aerobic HTOs as the main body was proposed, and a set of wheat starch wastewater treatment and biogas collection, purification and utilization system was designed.

The advantage of this process is that it can not only make the treated starch wastewater meet the discharge requirements, but also improve the energy generated by anaerobic biological treatment. The designed wastewater treatment capacity is 2000m3 d, COD is 12000 20000mg L, BOD5=6000 10000mg L, SS=9000 10000mg L. The actual engineering operation data show that the wastewater treatment and biogas utilization scheme proposed in this paper not only has a good treatment effect on COD in high-concentration wheat starch wastewater, with a COD removal rate of more than 95%, but also has a significant removal effect on ammonia nitrogen, overcoming the shortcomings of poor denitrification ability of the previous process, and can also use biogas, with a biogas output of 10000 13000m3 d, which is used as fuel into the gas boiler, and the steam produced is used in the vehicle.

After treatment, the COD, BOD5, SS and NH3-N of the wastewater are reduced to below 100mg L, 20mg L, 30mg L and 15mg L respectively, which meets the requirements of the indirect discharge concentration limit of water pollutants in new enterprises in the "Starch Industry Water Pollutant Discharge Standard" (GB25461-2010). The advantages of this process are low footprint, relatively stable operation, low energy consumption and low maintenance. This project case provides a practical method for the treatment of wheat starch wastewater, and can be promoted and applied as a demonstration project.

It also provides an important reference for other industries to obtain the dual benefits of environmental protection and economy in wastewater treatment.

Biogas is a gas mixture whose main component is methane, followed by carbon dioxide, hydrogen sulfide (H2S), nitrogen and others. In the composition of biogas, the combustible components include methane, hydrogen sulfide, carbon monoxide and heavy hydrocarbons. Non-flammable components include gases such as carbon dioxide, nitrogen, and ammonia. In the biogas composition, the methane content is 55% 70%, the carbon dioxide content is 28% 44%, and the average hydrogen sulfide content is.

The heat is because of the chemical reaction between hydrogen sulfide and desulfurizer, you can take a cool place to dry for a period of time, and you must change it often, otherwise it will damage your stove, hydrogen sulfide will corrode him, the purpose of installing desulfurizer is to protect the stove, lamps, and there is no technician to install the time You say? If you still don't understand, ask me for this information.

This friend answered very well, and I added that the biogas purifier can only be desulphurized if it works, because hydrogen sulfide and sulfur dioxide have a great corrosive effect on gas appliances and electrical appliances, so the biogas purifier should be installed.

As long as the biogas purifier is working, it will heat up. You sit in the room and don't feel anything; If you go out for a run, you feel hot all over; The "cat" on the Internet has just been opened and has not been heated, you have no way to access the Internet, and after 2 minutes, the cat is hot, so you can connect to broadband and open the browser. The principle is the same.

You don't have to worry about the biogas purifier heating up, the biogas purifier doesn't heat up before you can worry about it.

Fever! My personal opinion is that it is the aerobic entry that produces a reducing reaction!

Your reasons may be:

1. The biogas digester (heavy) is newly sealed and used, and there is air in it;

2. There is moisture in the pipe;

Do not let the air into the biogas purifier, the biogas purifier pays special attention to the entry of air when discharging the biogas digester, or it will not produce high temperature, if it is plastic, it will be burned out!

Restoration is as the first floor says: it should be restored in a cool place with ventilation!

The biogas is not pure, there is water in it, and there may be air mixed in it, just take it out and restore it, don't forget to be in a cool and ventilated place.

1.It is normal to warm up slightly during use.

2.If the temperature is too high, air may be mixed in.
