(1) The feces and urine of the pig farm were collected, and the COD, ammonia nitrogen, kjeldahl nitrogen and total phosphorus content in the urine obtained by the separation were measured, and the results are shown in Table 1.
The measuring method comprises the following steps: the Chemical Oxygen Demand (COD) of the urine sample is measured by using a GB/11914-89 potassium dichromate method, the Total Phosphorus (TP) is measured by using a GB11893-89 potassium dichromate method, the KN is measured by using a CB11891-89 potassium dichromate method, and the ammonia nitrogen is measured by using a titration method.
Table 1 measurement results
| Measurement index | Content of |
| COD/mg·L -1 | 14365.32 |

(2) The method of example 3 was used as an experimental group;
control group 1: the procedure of example 3 was followed with the following modifications: after the fermentation of the step (3) is completed, a product is obtained without adding ammonia nitrogen remover;
control group 2: the procedure of example 3 was followed with the following modifications: after the fermentation in the step (3) is completed, adding ammonia nitrogen remover (Hebei Kaixing chemical Co., ltd.) purchased through commercial way for treatment to obtain the product.
Each treatment was repeated 3 times, and after the experiment was completed, the COD, ammonia nitrogen, kjeldahl nitrogen and total phosphorus content of each treatment were measured and averaged. The results are shown in Table 2.
Table 2 measurement results of each treatment
As can be seen from the measurement data in Table 2, the ammonia nitrogen removal effect of the experimental group is the best, and the control group 2 is the next, whereas the control group 1 only performs the fermentation process of the starter, and does not add the ammonia nitrogen removal agent to perform the second fermentation, so that the ammonia nitrogen removal effect is the worst. The comparison of the data of the experimental group and the control group 2 also shows that the optimal ammonia, nitrogen and phosphorus removal effect can be achieved only by adopting the ammonia nitrogen remover disclosed by the invention, and the damage to the growth of crops caused by the excessive ammonia nitrogen content in the liquid fertilizer is avoided.
Example 5
Fertilizer efficiency verification test: selecting a block with a size of 1500m 2 Is divided into 15 test areas on average randomly to plant corn.
The experimental group is the fertilizer obtained in example 3, the application method is: the organic liquid fertilizer for pig urine is diluted according to the fertilizer-water ratio of 1:5 and then applied with water in the period of jointing, booting and blooming of corn, and 100kg of diluted organic liquid fertilizer for pig urine is used in each mu of each period.
Control group 3 was identical to control group 1 in example 4, control group 4 was identical to control group 2 in example 4, and the administration method was identical to that of the experimental group.
Control group 5: conventional fertilizer for corn (fertilizer for corn of smini) was applied according to the method of the specification.
Blank control group: no fertilizer is applied during the growing period of the corn.
The experimental group, the control group 3-5 and the blank control group are randomly used in three different test areas respectively, and all the test groups are identical in other management methods except for different fertilizer use. After harvesting corn, the acre yield is calculated and averaged. The results are shown in Table 3.
TABLE 3 yield statistics
| Yield/(kg/mu) | |
| Experimental group | 498.6 |
| Control group 3 | 368.9 |
| Control group 4 | 426.5 |
| Control group 5 | 458.5 |
| Blank control group | 256.2 |
As can be seen from the data obtained in Table 3, the corn yield of the experimental group is highest and can reach 498.6 kg/mu, which is improved by 35.2% compared with the control group 3, 16.9% compared with the control group 4 and 8.7% compared with the control group 5. Therefore, the fertilizer efficiency of the organic liquid fertilizer for pig urine is better than that of the traditional chemical fertilizer. From the comparison of the data of the experimental group, the control group 3 and the control group 4, the negative influence of the liquid fertilizer on the growth of crops can be avoided only by sufficiently removing ammonia nitrogen and other elements in the urine raw material.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
