2. Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to the algorithm to "mine" bitcoin. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

3. API keys are used to program transactions. One time password, with Google verifier. Download Google verifier to your mobile phone and install it. Scan the two-dimensional code with a verifier to get a one-time password. studybtc
4. Google's authentication program can only read the QR code generated by Google's two authentication systems, and other programs may not be able to read it.
5. It's hard to find this. It's better to change to a better exchange, such as bitoffer
6. Look at your own security risk awareness. Is it better to open Google than not?
7. You can provide information to unbind, provide binding mobile phone number, real name authentication ID number, RMB recharge or cash bank card number, the latest 3 RMB recharge online banking payment screenshots, the relevant staff audit no mistake, you can help you to unbind.
8. 1. A solution is a solution (proposal, schele) for some problems, deficiencies, defects, requirements, etc., which have been reflected or can be expected, and can ensure effective implementation.
2. The above definition is a list of solutions to a problem, which literally means it solutions
3. In view of some common problems in a certain instry, the corresponding supporting software or hardware solutions are given. For example, the financial software can solve the tedious manual accounting, inconvenient management and other problems, the ERP software can solve the company's purchase, sales and inventory problems, and Hadoop can solve the slow reading speed of network big data storage.

9. ① Spray water. This is one of the most commonly used physical methods. Foam is reced by spraying water or water droplets to break bubbles that float on the surface. The dispersed sludge particles partially recovered the sedimentation performance, but filamentous bacteria still existed in the mixed liquid, so the foam phenomenon could not be fundamentally eliminated.
2. Add defoamer. Bactericides with strong oxidizing properties, such as chlorine, ozone and peroxide, can be used. There are also commercial reagents proced by polyethylene glycol and silicone, and mixed reagents of ferric chloride and copper pickling solution. The action of the agent can only rece the growth of the foam, but can not eliminate the formation of the foam. However, the widely used bactericides generally have negative effects, because excessive or improper dosing position will greatly rece the number of flocculent bacteria and the total biomass in the reaction tank< (3) rece the sludge age. Generally, the residence time of sludge in aeration tank is reced to inhibit the growth of Actinomycetes with long growth period. It has been proved by practice that when the sludge residence time is 5~6 D, the growth of Nocardia bacteria can be effectively controlled, so as to avoid the foam problem arising from it (8, 9). However, there are many inapplicable aspects to rece the sludge age: when nitrification is needed, the sludge residence time needs at least 6 days in cold season, which is in contradiction with this method; In addition, microthrix parvicella and some filamentous bacteria were not affected by sludge age
4. Return the supernatant of anaerobic digestion tank. Experiments have shown that the method of returning supernatant from anaerobic digestion tank to aeration tank can control the formation of bubbles on the surface of aeration tank. The main function of the supernatant of anaerobic digestion tank is to inhibit Rhodococcus bacteria, but this method has not achieved the same success as the laboratory in several wastewater treatment plants. Because the supernatant of anaerobic digestion tank contains high concentration of aerobic substrate and ammonia nitrogen, they will affect the final effluent quality, so they should be used cautiously
5. Adding special microorganism. Some studies have suggested that some special strains can eliminate the activity of Nocardia, including protozoa, nephromorpha, etc. In addition, increasing the number of predatory and antagonistic microorganisms can control some of the foam bacteria [5].
6 selector. The selector is to create various reaction environments (oxygen, organic load or sludge concentration, etc.) to select the priority microorganisms and eliminate other microorganisms. It has been reported that aerobic selector can control M. parvicella to a certain extent, but has no significant effect on Nocardia; The anoxic selector had a control effect on Nocardia, but had no effect on M. parvicella Hy6969132)
bubble problem many reasons, depending on the specific circumstances, in addition to the reasons mentioned above, the following may also cause a large number of foam.1. water phosphate content is too high will also proce
2. water contains the surface active substances
3., filamentous bacteria excessive growth will lead to bacterial gel carrying a large amount of air, thus forming stable on the water surface. It is difficult to remove the dross froth. It has been proved that excessive growth of filamentous bacteria is the main cause of foams formation.
4. if the waste water contains excessive fatty acids, the sludge retention time of the system is longer and the sludge reflux rate is low. The lower F/M ratio will cause excessive growth of filamentous bacteria, resulting in foam proction.
elimination and control:
commonly used are: surface high speed flow injection.
control of sludge residence time
increase of reflux ratio and F / M ratio
use of defoamer
the above problems are either low efficiency or high cost
at present, there is a kind of process called FFO, which can be used for reference from process design
FFO operation technology is the abbreviation of nutrient and deficiency technology, According to the difference of growth kinetics between filamentous bacteria and common bacteria, the two-stage live fouling method is designed (you should know how to do it)
the primary is high F / m, about 0.8, low reflux ratio is about 0.06, the secondary is low f / m, about 0.2, high reflux ratio is about 0.21
ha, only to control the growth of old silk, The problem is solved.
foam is divided into two main types: chemical foam and biological foam.
chemical foam is formed by the washing and stripping of aerated detergent and some instrial surface materials. With the increase of activated sludge, a large number of detergents or surface substances will be absorbed and decomposed by microorganisms, and the foam will graally disappear. Defoamer can be added, or powdered activated carbon can be added, which can not only absorb some active agents and harmful substances, but also provide biological carrier and increase biomass
effluent from treatment plants or floating scum with incomplete oil and lipids is easy to proce biological foam, which is mainly caused by Nocardia. Check your steam flotation tank to see if the air flotation tank has not been adjusted properly (including the steam water ratio, whether the releaser is blocked, whether the dosing system and water inflow are too large). The key is to get rid of the oil.

10. At present, there are many mainstream virtual currency platforms in the market, and the scale of this rec project in China is relatively large. Because I see a lot of people trading virtual currency in it. Their income proct is called rec wealth currency, and their income and running water are in the front row. Judging from the data available now, the annual profit is indeed relatively objective. The application of digital currency in the future will become more convenient. If you want to make your future more secure, it is very necessary to choose a proct worthy of investment,
