Embodiment 1

[0048] After degreening, 1000kg of moso bamboo production raw materials are longitudinally rolled, cut into strips, and loosened to make moso bamboo shreds;

[0049] Place the above-mentioned moso bamboo shreds in a high-pressure sealed tank, energize and heat to generate steam, make the air pressure in the tank reach 0.2MPa, control the temperature at 145±5°C, carbonize for 150min, collect the liquid in the carbonization process, and obtain 175kg of moso bamboo carbonization wastewater, placed in a holding tank;

[0050] The carbonized waste water of moso bamboo is passed through a quartz sand column filter, from top to bottom, followed by quartz sand with a particle diameter of 2 to 4 mm (filling height is 120 cm), and quartz sand with a particle diameter of 8 to 10 mm (filling height is 120 cm). 80cm), a particle size of 2mm quartz sand (filling height is 100cm), the liquid phase is collected to obtain the first filtrate;

[0051] Add 8kg active bamboo charcoal powder (par...

Embodiment 2

[0055] A Field Test of a Crop Growth Regulator—Tea Tree

[0056] Test location: Huoshan County, Anhui Province.

[0057] Test time: January 2019 to April 2019.

[0058] Test implementation: The test material is 10-year-old tea tree.

[0059] Using the crop growth regulator obtained in Example 1, spraying test (1 mu) was carried out on 2 acres of tea trees with consistent growth, and sprayed after 60 times of dilution, respectively on 2019.01. 20. Each interval is 10-12 days (treatment), and the same amount of water is sprayed as a control (1 mu) each time. Harvest was carried out from April 8th to April 10th of the same year, and the yield of fresh leaves was measured. The average yield of the treatment group was 315.5kg / mu, and that of the control group was 257.4kg / mu.

Embodiment 3

[0061] A Field Test of a Crop Growth Regulator—Camellia oleifera

[0062] Test location: Huoshan County, Anhui Province.

[0063] Test time: from June 2019 to October 2019.

[0064] Test implementation: The test material is 10-year-old Camellia oleifera.

[0065] Using the crop growth regulator obtained in Example 1, spraying test (30 plants) was carried out on 60 Camellia oleifera plants with consistent growth, diluted 50 times and sprayed, the number of times was 3 times, respectively on 2019.06.10, 2019.06.20, 2019.06.30, Each interval is 10 days (treatment), and each time the same amount of water is sprayed as a control (30 plants). After harvesting on October 10 of the same year, the fresh weight of Camellia oleifera was measured. The average yield of the treatment group was 14.25kg / plant, and that of the control group was 11.33kg / plant.

Abstract

The invention provides a harmless treatment method for wastewater generated in wet carbonization of moso bamboos, a crop growth regulator and a use method of the crop growth regulator. The invention belongs to the technical field of waste recycling; the harmless treatment method provided by the invention can remove tar and other impurities in wastewater, a middle-layer liquid phase obtained through standing can be used for preparing the crop growth regulator, and recycling of moso bamboo carbonization wastewater is achieved. Meanwhile, the harmless treatment method provided by the invention issimple and easy to operate. The invention also provides the crop growth regulator which takes the middle-layer liquid phase obtained by harmless treatment of the moso bamboo carbonization wastewateras a main component, and the liquid phase contains organic acid compounds, polyphenol compounds and mineral elements (such as calcium, iron and the like), so that a certain nutrition source can be provided for plant growth, and the growth of crops can be promoted.

Description

technical field [0001] The invention relates to the technical field of waste recycling, in particular to a harmless treatment method for moso bamboo wet carbonization wastewater, a crop growth regulator and a use method thereof. Background technique [0002] In the process of using moso bamboo to produce carbonized bamboo shreds, it is necessary to place the decomposed moso bamboo shreds in a closed container and inject high-pressure saturated steam for wet carbonization. During the wet carbonization process, the high-pressure steam condenses and the dissolved substances of moso bamboo form a wet carbonization reaction liquid. The wet carbonization reaction solution has high acidity, high COD value, and is difficult to degrade. Direct discharge will cause environmental pollution, and it is a kind of production wastewater that is difficult to treat. [0003] At present, harmless treatment is carried out through physical and chemical treatment systems, biochemical treatment s...
