Embodiment 1

[0042] Step 1. During the processing of marigolds, fermented marigolds have a high water content, and are dehydrated by pressing. After pressing, the marigold flower mud is transported to drum drying by a scraper for subsequent processing, and the production waste liquid is to be treated;

[0043] Step 2. After the production waste liquid to be treated in the previous step is subjected to natural precipitation and separation, the bottom flower mud is returned to the scraper to be transported into the subsequent production and processing process, and the broken flower mud that is difficult to separate is to be processed;

[0044] Step 3: After the first separation of natural precipitation, the broken flowers contained in the middle and upper parts of the production waste liquid are separated, and the production waste liquid is separated again through the combined process of air flotation and sedimentation, and the air is pressurized to 0.25Mpa by pressurized dissolved air flotati...

Embodiment 2

[0049] Step 1. During the processing of marigolds, fermented marigolds have a high water content, and are dehydrated by pressing. After pressing, the marigold flower mud is transported to drum drying by a scraper for subsequent processing, and the production waste liquid is to be treated;

[0050] Step 2. After the production waste liquid to be treated in the previous step is naturally precipitated and separated, the bottom flower mud is returned to the scraper to be transported into the subsequent production and processing process, and the broken flower mud that is difficult to separate is to be processed;

[0051] Step 3: After the primary separation of natural precipitation, the broken flowers contained in the middle and upper parts of the production waste liquid are carried out, and the production waste liquid is subjected to secondary separation through the air flotation and sedimentation combined process, and the air is pressurized to 0.4Mpa by pressurized dissolved air fl...

Embodiment 3

[0056] Step 1. During the processing of marigolds, fermented marigolds have a high water content, and are dehydrated by pressing. After pressing, the marigold flower mud is transported to drum drying by a scraper for subsequent processing, and the production waste liquid is to be treated;

[0057] Step 2. After the production waste liquid to be treated in the previous step is naturally precipitated and separated, the bottom flower mud is returned to the scraper to enter the subsequent production and processing process, and the broken flower mud that is difficult to separate is to be processed;

[0058] Step 3: After the first separation of natural precipitation, the broken flowers contained in the middle and upper parts of the production waste liquid are separated, and the production waste liquid is separated again through the combined process of air flotation and sedimentation, and the air is pressurized to 0.55Mpa by pressurized dissolved air flotation to make the air It is i...

Abstract

The invention discloses a process for recycling marigold production waste liquid, and belongs to the field of marigold production waste liquid recycling. Waste liquid in the marigold production process is secondarily separated into clear liquid and flower mud through a physical separation process, the flower mud returns to an original processing and production process, zymophyte, urea and the likeare added for micro-aeration fermentation after the PH value of the clear liquid is adjusted through microbial strains, the clear liquid enters a smashing and homogenizing process after being stirred, and the organic liquid fertilizer is obtained after filtering and filling. According to the method, water and flower mud in the marigold production waste liquid are separated and then subjected to graded utilization, resource recycling is achieved, the yield of marigold production and processing products is increased, the obtained organic liquid fertilizer is reused in marigold planting farmlands, ecological circular agriculture is achieved, and the process has great social benefits, environmental benefits and economic values.

Description

technical field [0001] The invention relates to the technical field of production waste liquid treatment and resource recycling, in particular to a marigold production waste liquid recycling process, which is used for the recycling of marigold production wastewater. Background technique [0002] Marigold extract is prepared from marigold flowers through fermentation, granulation, extraction, separation and other processes, and can be widely used in food, health care products, medicine, feed and other industries. [0003] Marigold production waste liquid is the fermentation waste liquid and pressing waste liquid produced during the processing of marigold flowers. The waste liquid has a pH of 3-5, is acidic, and is rich in lactic acid, nitrogen, phosphorus, potassium, trace nutrients and high organic matter. Such as direct discharge will cause serious pollution to the environment. Treating marigold pressing waste liquid as waste liquid not only requires high investment in sew...
