Description

Technical Field

[0001] This invention belongs to the field of pollution-free treatment and application technology of medicine residue from cold-relieving oral liquids, specifically involving a pollution-free treatment method for mixing medicine residue from cold-relieving oral liquids with cow dung and its application. Background Technology

[0002] Influenza is a global public health problem, causing numerous cases and deaths every year. Antiviral cold medicines, used for treating influenza, are in huge demand.

[0003] Antiviral cold medicines are divided into traditional Chinese medicine (TCM) preparations and Western medicine preparations. Compared with Western medicine preparations, TCM preparations have fewer toxic side effects and better safety, thus having a higher market share. To meet the large demand for TCM antiviral cold medicine preparations, the demand for raw TCM herbs is also very high. Common raw material combinations for TCM antiviral cold medicines include Isatis root, Bupleurum root, honeysuckle flower, and forsythia. In the production of TCM antiviral cold medicines, the raw materials are usually extracted, and the extracts are further processed into drugs. However, there is currently limited research on the TCM residue generated after extraction, and effective, pollution-free treatment methods are lacking. Summary of the Invention

[0004] The purpose of this invention is to provide a method for the pollution-free treatment of the residue from an oral cold remedy mixed with cow dung and its application. By co-fermenting the residue from the oral cold remedy with cow dung, the pollution-free treatment of the residue is achieved. Simultaneously, the resulting fermentation product is used to prepare an organic tomato seedling substrate, exhibiting excellent cultivation results, significantly superior to existing conventional organic seedling substrates.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] One of the technical solutions of this invention is to provide a pollution-free treatment method for mixing the residue of anti-cold oral liquid medicine with cow dung, comprising the following steps:

[0007] Mix the dregs of the oral cold medicine with fresh cow manure, adjust the moisture content, and compost aerobically until fully decomposed to complete the pollution-free treatment.

[0008] The raw materials for the medicinal residue in the oral cold medicine are Isatis root, Bupleurum, honeysuckle and forsythia.

[0009] Preferably, the mass ratio of medicinal residue to fresh cow dung in the oral cold remedy is 2:1.

[0010] Preferably, the moisture content is 65%.

[0011] Preferably, the ambient temperature during the aerobic composting process is not lower than 15°C.

[0012] Preferably, the turning time for the aerobic compost is 6 days.

[0013] The second technical solution of the present invention provides a fermentation product obtained by a pollution-free treatment method of mixing the residue of the above-mentioned anti-cold oral liquid with cow dung.

[0014] The third technical solution of the present invention provides an application of the above-mentioned fermentation product in the preparation of organic tomato seedling substrate.

[0015] The fourth technical solution of the present invention: an organic tomato seedling substrate, composed of the product after drying, crushing and sieving of the above-mentioned fermentation products, vermiculite and peat moss.

[0016] Preferably, the sieve is a sieve with apertures of 5mm and 1mm, retaining a portion of 1-5mm.

[0017] The beneficial technical effects of the present invention are as follows:

[0018] This invention uses the residue of Chinese medicinal herbs (Isatis root, Bupleurum root, honeysuckle, and forsythia) from anti-cold oral liquid as raw materials. Since the C / N ratio and pH value of the raw materials themselves meet the initial process conditions for aerobic composting, the required adjustment process is greatly reduced, thus improving the efficiency of subsequent production.

[0019] The raw materials used in this invention contain a large amount of organic matter, which meets the conditions for aerobic composting and heating. Therefore, no microbial agents were used for optimization. The raw materials themselves can achieve thorough decomposition and kill pathogens and weed seeds under the generated high temperature conditions.

[0020] The cow dung added in this invention contains a large amount of humus and microorganisms, which allows the compost to quickly enter the high-temperature period, and the high-temperature period lasts longer compared with other raw materials of the same volume. Under the metabolic action of microorganisms, the organic matter in the medicinal herb residue can be rapidly degraded, allowing the compost to fully decompose and enter the cooling stage earlier.

[0021] This invention makes full use of the solid waste resources of Chinese medicinal herb residue, turning waste into treasure, solving the problem of ineffective treatment and utilization of medicinal herb residue waste in Chinese medicinal herb production units, and providing a better solution for the ineffective treatment of manure waste in livestock breeding enterprises, reducing ecological and environmental pollution, and opening up a more reasonable and practical new path for the treatment of Chinese medicinal herb residue waste and livestock manure waste.

[0022] The raw materials specified in this invention are readily available, and the pollution-free treatment method of mixing the residue of the cold-fighting oral liquid with cow dung is simple to operate, low in cost, and highly efficient. The residue of the cold-fighting oral liquid selected in this invention has a high content of fruiting plants, and the nutrients it provides are consistent with the growth process of tomato seedlings. Therefore, the fermentation products can provide a certain scientific research basis for the preparation of organic seedling substrate for commercial tomatoes. Attached Figure Description

[0040] The Chinese herbal residue used in the embodiments and comparative examples of this invention for the anti-cold oral liquid was obtained from the Traditional Chinese Medicine Pharmaceutical Laboratory of Daqing Oilfield General Hospital, Heilongjiang Province. The dry weight ratio of its components, Isatis root, Bupleurum root, Honeysuckle flower, and Forsythia fruit, was 1:3:3:6, the C / N ratio was 25, the pH value was 6.8, and the initial moisture content was 58%. The heavy metal content is shown in Table 1. Fresh cow dung was purchased from Anda City, Suihua City, Heilongjiang Province. Its C / N ratio was 22:1, the pH value was 7.8, and the initial moisture content was 64%. Vermiculite, peat moss, and commercial substrates were all purchased from Bowei Materials Distribution Center in Sartu District, Daqing City.

[0041] Table 1. Results of heavy metal detection in the residue of anti-cold oral liquid.

[0042]

[0043] Table 1 shows that the heavy metal content in the medicinal residue of the cold-fighting oral liquid used in this invention is within the qualified range and meets the national industry standards.

[0044] Comparative Example 1

[0045] Using the residue of traditional Chinese medicine for cold medicine as raw material, the moisture content was adjusted to 65% and the C / N ratio was 25:1 to obtain the initial material for aerobic composting;

[0046] After the initial materials for aerobic composting are mixed evenly, they are filled into a cylindrical, rotatable aerobic composting reaction vessel with a length of 1m and a diameter of 0.7m, with a filling mass of 20kg. Aerobic composting is carried out (the maximum temperature of the compost pile can reach 50-60℃, and the cycle is 46 days). The compost is turned over once every 6 days to complete the pollution-free treatment and obtain the fermentation products.

[0047] The fermentation product contained 2.345% nitrogen, 0.224% phosphorus, 1.142% potassium, 1.304 g / kg available nitrogen, 0.188 mg / kg available phosphorus, 4.833 mg / kg available potassium, 42.14% total organic carbon, 7.25 pH, 1.005 ms / cm EC, and 50% water content.

[0048] Example 1

[0049] Using the residue of oral cold medicine and fresh cow dung as raw materials, the residue of oral cold medicine and fresh cow dung were mixed evenly at a mass ratio of 1:1 and the moisture content was adjusted to 65% and the C / N ratio was 23.5:1 to obtain the initial material for aerobic composting.

[0050] After the initial materials for aerobic composting are mixed evenly, they are filled into a cylindrical, rotatable aerobic composting reaction vessel with a length of 1m and a diameter of 0.7m, with a filling mass of 20kg. Aerobic composting is carried out (the maximum temperature of the compost pile can reach 50-60℃, and the cycle is 43 days). The compost is turned over once every 6 days to complete the pollution-free treatment and obtain the fermentation products.

[0051] The fermentation product contained 2.665% nitrogen, 0.334% phosphorus, 2.235% potassium, 1.508 g / kg available nitrogen, 0.318 mg / kg available phosphorus, 5.501 mg / kg available potassium, 32.20% total organic carbon, 7.64 pH, 2.686 ms / cm EC, and 50% moisture content.

[0052] Example 2

[0053] Using the residue of oral cold medicine and fresh cow dung as raw materials, the residue of oral cold medicine and fresh cow dung were mixed evenly at a mass ratio of 2:1 and the moisture content was adjusted to 65% and the C / N ratio was 24:1 to obtain the initial material for aerobic composting.

[0054] After the initial materials for aerobic composting are mixed evenly, they are filled into a cylindrical, rotatable aerobic composting reaction vessel with a length of 1m and a diameter of 0.7m, with a filling mass of 20kg. Aerobic composting is carried out (the maximum temperature of the compost pile can reach 50-60℃, and the cycle is 46 days). The compost is turned over once every 6 days to complete the pollution-free treatment and obtain the fermentation products.

[0055] The fermentation product contained 2.225% nitrogen, 0.256% phosphorus, 1.258% potassium, 1.295 g / kg available nitrogen, 0.335 mg / kg available phosphorus, 5.112 mg / kg available potassium, 33.01% total organic carbon, 7.89 pH, 2.122 ms / cm EC, and 50% moisture content.

[0056] Example 3

[0057] Using the residue of oral cold medicine and fresh cow dung as raw materials, the residue of oral cold medicine and fresh cow dung were mixed evenly at a mass ratio of 4:3 and the moisture content was adjusted to 65% with a C / N ratio of 23.7:1 to obtain the initial material for aerobic composting.

[0058] After the initial materials for aerobic composting are mixed evenly, they are filled into a cylindrical, rotatable aerobic composting reaction vessel with a length of 1m and a diameter of 0.7m, with a filling mass of 20kg. Aerobic composting is carried out (the maximum temperature of the compost pile can reach 50-60℃, and the cycle is 43 days). The compost is turned over once every 6 days to complete the pollution-free treatment and obtain the fermentation products.

[0059] The fermentation product contained 1.811% nitrogen, 0.247% phosphorus, 1.326% potassium, 1.007 g / kg available nitrogen, 0.304 mg / kg available phosphorus, 4.943 mg / kg available potassium, 32.32% total organic carbon, 7.89 pH, 1.633 ms / cm EC, and 50% moisture content.

[0060] The fermentation process and fermentation products of Comparative Example 1 and Examples 1-3 were tested, and the test results are shown in Table 2.

[0061] From the start of composting, the temperature of the compost should be measured twice a day, once in the morning and once in the evening, and the ambient temperature should also be measured. The average value should be taken as the temperature of the compost and the ambient temperature for that day. This should continue until the temperature of the compost approaches the ambient temperature. Due to environmental factors, the end time of composting may vary slightly.

[0062] The sampling method during composting is as follows: take samples once each from 10cm, 30cm and 50cm from the top, mix the three samples thoroughly, use them as the samples of the day, and store them in an environment of -40℃ for subsequent germination index tests and compost-related index detection.

[0063] Seed germination index determination method: Weigh 10.0g of fermentation product, add water of the corresponding mass according to the solid-liquid ratio (mass / volume) 1:10, shake horizontally at 150r / min for 1h at room temperature, let stand for 30min, take the supernatant and filter it on a filter device with filter paper pre-installed, and collect the filtered extract. Place two qualitative filter papers in a 9cm petri dish, select 10 cucumber seeds of basically the same size and plump, place them evenly in the petri dish, add 10.0mL of extract, use deionized water as a control, repeat three times, and culture at 25℃ for 48h. Count the number of germinated seeds and measure the root length with vernier calipers. Seed germination index (GI), expressed as %, is calculated according to formula (1).

[0064]

[0065] Images of cucumber seeds after culturing were shown in the seed germination index determination of each group's fermentation products. Figure 1 From left to right, they are the control group, comparative example 1, example 2, example 3, and example 1.

[0066] Table 2 Results of Fermentation Product Index Detection

[0067]

[0068] Table 2 shows that, compared with Comparative Example 1, Example 1 entered the high-temperature period (≥50℃) earlier. Compared with Comparative Example 1, Examples 1-3 had a longer high-temperature period duration of 1-5 days and a higher maximum compost temperature of 6.7-7.1℃. Examples 2-3 ended composting 2 days earlier than Examples 1 and Comparative Example 1 (composting ended when the temperature approached the ambient temperature and tended to stabilize). This indicates that adding an appropriate proportion of fresh cow manure helps to increase the composting heating rate, prolong the high-temperature period duration, and shorten the composting time.

[0069] The organic matter content, pH, EC, germination index, nitrogen, phosphorus, and potassium content of the fermentation products prepared by Comparative Example 1 and Examples 1-3 all meet the technical requirements of organic fertilizer (NY525-2021). Moreover, the germination index is significantly better than the standard requirement of ≥70%, indicating that the fermentation products prepared by the pollution-free treatment method of mixing the residue of anti-cold oral liquid with cow manure have a high degree of composting and are non-toxic as organic fertilizer, which promotes the germination of crop seeds.

[0070] Figure 2 This shows the change in pile temperature over time during the fermentation process of Comparative Example 1 and Examples 1-3.

[0071] Figure 3 This shows the change in pH value of the fermentation pile over time during the fermentation process of Comparative Example 1 and Examples 1-3.

[0080] Figure 12 Seed germination index of the fermentation products of Comparative Example 1 and Examples 1-3.

[0081] Figures 2 to 10 During the process, samples were taken every 6 days after the pile was turned over. The last sampling time was determined in advance based on the pile temperature and ambient temperature to prevent the inactivation of microorganisms in the samples.

[0082] Figure 2 The results show that turning and turning the compost can effectively control the temperature of the compost within a limited range, thus ensuring the activity of bacteria in the compost pile and achieving the effect of killing weed seeds and pathogens. In addition, the temperature of Examples 2-3 in the figure tends to stabilize at near the ambient temperature after 43 days, indicating that Examples 2-3 completed aerobic composting 3 days ahead of schedule.

[0083] The results show that when using only the residue from the cold-relieving oral liquid as raw material for aerobic composting, the temperature rise was relatively slow during the experiment, and the maximum temperature was lower compared to the treatment group. The temperature of the compost pile also dropped rapidly. After 46 days of composting, the organic matter content in the material was lower than that of the initial material, and the seed germination index was also relatively low. This indicates that although aerobic composting using only the residue from the cold-relieving oral liquid can achieve the maturity standard, the degree of maturity is lower compared to co-fermentation with fresh cow manure. Co-fermentation of the residue from the cold-relieving oral liquid with fresh cow manure can reduce the toxicity to seeds.

[0084] The fermentation product obtained in Example 2 was further applied to the preparation of organic tomato seedling substrate, and its seedling effect was tested (the 1-5 mm portion of the fermentation product obtained in Example 2 after drying at 105℃ for 12 hours and crushing was used as raw material).
