Background
With the rapid development of economy, the living standard of masses is increasingly improved, and the demands of people on animal proteins such as pigs, cows, sheep, chickens, ducks and the like are continuously increased. The meat food with the livestock and poultry products as the main food is taken as daily consumer goods on dining tables of people, promotes the development of livestock and poultry breeding industry to be more and more different, and simultaneously promotes the construction of standardized and large-scale livestock and poultry farms. On the other hand, the ecological environment pollution problem caused by the large-scale rapid expansion of the livestock and poultry raising industry is also increasing. The main reason is that a great amount of waste is generated in the livestock and poultry breeding process, and the surrounding ecological environment is greatly influenced. The main points are as follows:
Firstly, the livestock and poultry breeding waste contains a large amount of pathogenic microorganisms and parasitic ova, and is also a main medium for breeding mosquitoes and flies. With the continuous increase of the number of livestock and poultry, pathogenic microorganisms and parasitic ova in the environment can be greatly propagated and spread, so that people and livestock contacted with the microorganisms and parasitic ova are infected. Once the pestilence of livestock and poultry is exploded and is not effectively controlled in time, the epidemic situation spread in a large area is easily caused.
Secondly, livestock farms generally adopt a large amount of water to clean the farms, so that water resources are wasted, and a large amount of pollutants are carried in the generated sewage. The related data show that the concentration of NH3-N (ammonia nitrogen content index) in the sewage discharged by livestock and poultry farms can reach 4000mg/L, which is more than 100 times of the sewage discharge standard of enterprises. When sewage is discharged into natural environment, not only can the deterioration of surrounding water quality be accelerated, but also water eutrophication can be caused, nitrogen and phosphorus in the water quality can be increased, and the local aquaculture development and water ecology are seriously threatened.

2. Analysis of results:
for further researching the scientific rationality of the production scheme 3 obtained by the data transformation comprehensive evaluation model, simple analysis and discussion are made for the rationality of weight distribution affecting evaluation and the accuracy of experimental results under corresponding weights:
(1) Rationality analysis:
In order to achieve the aim of innocent treatment of livestock and poultry raising waste, the livestock and poultry raising waste collected from livestock and poultry farms is taken as a main raw material to be digested and degraded to produce the organic water-soluble fertilizer suitable for the integration of sugarcane planting and water-fertilizer. The control of the component content of the raw material and related factors in the production process has important influence on the production result, and is mainly represented by indexes such as pH value, ammonia nitrogen content, organic matter content, phosphorus content, sulfur content, COD and the like. The result of the production scheme 3 shows that the pH value, the organic matter content, the sulfur content and the COD in the six indexes are all in a reasonable interval, and the ammonia nitrogen content and the phosphorus content slightly exceed the reasonable interval, but can be regulated by changing the nitrogen content and the phosphorus content of the production raw materials. In combination, the various index conditions of the production scheme 3 are better than those of other production schemes. Therefore, the production result determined by combining the test and the data transformation comprehensive evaluation model has various index weights of omega j = (0.2315,0.2064,0.1529,0.0982,0.1973,0.1136) which is scientific and reasonable.
(2) Accuracy analysis:
The production schemes with the priority ranking of :F3→F9→F7→F8→F4→F1→F10→F2→F5→F6. and the maximum indexes in the reasonable interval can be simultaneously satisfied for the six indexes based on the data transformation comprehensive evaluation model, namely scheme 3 and scheme 8, which are all the production schemes with the maximum indexes in the reasonable interval. However, for scheme 8, the sulfur content is too high, exceeding 70% of the upper limit, belonging to a serious superscalar; while the ammonia nitrogen content and the phosphorus content of the scheme 3 exceeding the index range are slightly higher or slightly lower than a reasonable interval, the excess is only 10% and 22%. Thus, in a combined sense, the various indicators of production scheme 3 are indeed the most reasonable of all production schemes. Therefore, the production scheme obtained based on the data transformation comprehensive evaluation model is scientific and reasonable, and the result is relatively accurate.
From the above results, it can be seen that: the production scheme 3 selected by adopting the comprehensive evaluation model of uniform design and data transformation is ideal as the production scheme for producing the organic water-soluble fertilizer suitable for the integration of the water and fertilizer for sugarcane planting.

As shown in fig. 3 to 4, a reactor body 1, a reactor cover 2, a liquid baffle plate 5, a guide cylinder group 9, and a gas distributor 11. The outside of the reactor body 1 is wrapped by a jacket 7, and the internal medium can be adjusted according to the requirement to keep the temperature or refrigerate the reactor. The jacket 7 is provided with a bracket 8. The side wall of the reactor body 1 is provided with a probe sleeve 6 which can be used for placing probes of each parameter detector, and the probes are connected to external parameter monitoring equipment to realize real-time monitoring of relevant parameters inside the reactor. The periphery of the bottom of the reactor body 1 is provided with a discharge port 10 which is connected with a gas distributor 11. The reactor cover 2 is provided with a feed inlet 3 and an exhaust outlet 4, and a liquid baffle 5 is arranged between the reactor cover and the liquid level, so that the reaction raw materials can be prevented from being sprayed out along with the gas. In order to enable the reaction raw materials sprayed onto the liquid baffle plate 5 to quickly fall back into the reactor to participate in the reaction, the downward side of the liquid baffle plate is provided with a convex-concave surface, in particular a zigzag structure. The guide cylinder group 9 consists of five guide cylinders, and a guide plate 12 is arranged outside each guide cylinder. The four guide cylinders on the outer ring are provided with annular guide plates, and the central guide cylinder adopts a form of alternately distributing diamond guide plates and the annular guide plates. The guide plates 12 can be matched with annular guide plates on the inner wall of the reactor main body 1 to lead the reaction raw materials to baffle downwards between the guide plates 12, prolong the time for dissolving oxygen in the reaction raw materials, strengthen the gas exchange between strain cells and the reaction raw materials, fully mix different components in the reaction raw materials and strengthen the gas-liquid mass transfer. The guide cylinder group 9 adopts a combination mode of matching five guide cylinders to influence the flow direction of reaction raw materials, so that the flow field in the reactor can be changed to obtain vortex flow to strengthen mass transfer while the reaction raw materials are prevented from directly rising from the middle to the top. So that some solid matters in the initial stage of the reaction move together with the reaction raw materials and are decomposed, and the solid matters are prevented from accumulating under the guide plates 12 in the middle of the guide cylinder group 9. Each guide plate 12 is distributed with sieve holes 13 with different sizes, the cross section of each sieve hole 13 is in a ladder shape, and the upper part is wide and the lower part is narrow, so that the cross section area is continuously reduced when the reaction raw material flows through each sieve hole 13, the pressure is continuously increased, and the reaction raw material flows out of each sieve hole 13 and escapes due to the sudden increase of the cross section area and the pressure drop, so that the flow field effect is increased. The middle part of the guide cylinder is provided with the necking structure 14, and the gas phase and the liquid phase flow into the front half part of the necking structure 14 under high pressure, pass through the narrow throat and then escape from the rear half part, so that the flow velocity of the gas phase and the liquid phase is obviously improved, and the gas phase and the liquid phase are promoted to be fully mixed. Convex rings 15 are oppositely arranged at intervals in the guide cylinder to serve as compression surfaces, so that the pressure distribution near the area can be increased, the nearby reaction raw materials can quickly overflow to the upper side, and the circulation of the reaction raw materials is enhanced. The gas distributor 11 adopts a disc-type gas distributor 11, five round holes are formed in the upper surface of the disc-type gas distributor 11, the five round holes correspond to the five guide cylinders respectively, and only small holes are formed in the round holes, so that the ascending section and the descending section in the reactor can be clearly distinguished without disorder. The gas distributor 11 may be connected to an air pump for supplying the reactor. A pressure control system can be arranged between the gas distributor 11 and the air pump, and the pressure in the reactor is kept constant by adjusting a pressure control valve through an automatic control system while monitoring the pressure in the reactor in real time. The reactor comprises a reactor body 1 and a reactor cover 2.
In the production process, a necking structure is additionally arranged in the middle of the guide cylinder in order to accelerate the air flow in the fluid cylinder so as to be better mixed with the reaction raw materials. The specific parameters of the necking structure are determined as follows:
1. calculating the area ratio:
the flow of the air flow in the fluid cylinder is isentropic, the speed of sound is reached at the throat, and the Mach number accelerated to at the outlet of the fluid cylinder is Ma e. The area ratio of the outlet section to the throat section of the fluid cartridge is then:
Wherein A e is the outlet cross-sectional area; a t is throat area; gamma is the adiabatic index.
The gas introduced during production is sterile air, y=1.4, then:
thus, the area ratio of the outlet section of the device to the throat section can be obtained.
2. Checking working conditions:
The application does not need to accelerate the air flow to supersonic velocity, and the air flow always flows at subsonic velocity in the device, which belongs to working conditions Wherein/>P b is the downstream back pressure of the device and p 0 is the total upstream pressure of the device, i.e., the upstream-downstream pressure ratio within the fluid cartridge. /(I)For the third characteristic pressure ratio, the third characteristic pressure ratio can be obtained by checking a complete gas isentropic flow function table by a given area ratio or by calculating the third characteristic pressure ratio by the following mode:
Substituting y=1.4, then:
Substituting the area ratio into the above equation, and solving the equation can obtain Mach number Ma t. The characteristic pressure p 3 of the corresponding device can be obtained from the Mach number, and then the characteristic pressure p 3 can be obtained from a pneumatic function formula:
Because the utility model is influenced by the pressure control system in the production process, the internal pressure of the reactor is always kept between 0.1 and 0.15MPa, namely: downstream backpressure p b = 0.1-0.15 MPa. Let the total upstream pressure of the device be p 0, then:
If the pressure ratio of the device obtained by the area ratio is proved to meet the above formula, the device meets the requirements.
Taking a 100L reaction apparatus as an example:
The application needs to continuously adjust the fermentation liquor from the upper part of the reactor in the fermentation process, so as to facilitate the feeding of operators, thereby adopting lower height-diameter ratio. And because a plurality of convex rings are oppositely arranged at intervals in the guide cylinder, and the middle part is provided with a necking structure, energy loss is generated when the gas phase and the liquid phase flow through the places. An excessively high aspect ratio will greatly reduce the velocity of the gas-liquid two phases at the end of the rising section, thus setting the aspect ratio of the reactor to 5.
The application adopts pulse type air supply, the gas-liquid two phases rise rapidly in the rising section and fall slowly between the guide plates in the falling section. Therefore, the flow rate of the gas-liquid two-phase in the ascending section is increased, and the flow rate in the descending section is reduced, so that the gas-liquid mass transfer effect can be better enhanced. Smaller guide cylinder diameters and lower ascending and descending area ratios are then used.
Since the reactor height to diameter ratio is 5, the reactor internal cross-sectional area should be 0.1075m 2 and the height 0.925m. To achieve the above object, the rising section area/falling section area=0.6.
