Problems solved by technology

But the disadvantages are: because the concentration and chromaticity of various pollutants in the wastewater are high, the load of the biological pool is large, the residence time is long, the membrane is easy to be blocked or fails, the cost of membrane replacement is expensive, and it is difficult to ensure normal operation.

Embodiment 1

[0017] Example 1: The daily treatment of a landfill is 300m 3 Taking landfill leachate as an example, the treatment process is as follows figure 1 As shown in the design, the total residence time of the two-stage anaerobic tank is 2-3 days and a total of 600-900m 3 ;The design of the water distribution pool is 50m for any multiple of water distribution 3 ; According to different water quality, the total residence time of the three-level aerobic pool is at least 300m per day 3 ; filter tank 100m 3 ;Clear water pool 50m 3 . specific methods:

[0018] 1. Put bacteria in the anaerobic tank and aerobic tank. The bacterial species are: Achromobacter, Aerobacter, Alcaligenes, Nitrosomonas, Bacillus, Bacillus, Corynebacterium Genus, Comamonas, Flavobacterium, Microbacteria, Nocardia, Pseudomonas, Sarcines, Spirobacterium, Kineticia, Cochlamydia, Hirudovibrio One or more of the genus, Escherichia coli, Thiobacillus, Acinetobacter, Brevibacterium, Stemobacter or Cellop...

Embodiment 2

[0028] Example 2: A sugar factory has a daily treatment of 300m 3 Example of alcohol waste mash:

[0029] See Table 2 for the water quality of alcohol waste mash in a sugar factory

[0030]

[0031] The water quality comparison of each process before and after treatment is shown in Table 3 below

[0032]

[0033]

[0034] Note: The discharge standard is the "Comprehensive Wastewater Discharge Standard" ).

[0035] The treatment steps of this embodiment are the same as the landfill leachate treatment steps of the first embodiment. In order to save the operating cost to a greater extent, at the front end of the present invention, the alcohol waste mash from Guangxi Pingguo can be used as the patent for ash flushing water in the boiler, and the water after ash flushing can then enter the process of the present invention for treatment.

Embodiment 3

[0036] Example 3: The paint workshop of an automobile factory has a daily treatment of 300m 3 Example of electrophoretic paint phosphating wastewater:

[0037] The water quality comparison before and after the treatment of electrophoretic paint phosphating wastewater in the paint workshop of an automobile manufacturer is shown in Table 4 below:

[0038]

[0039] Note: The discharge standard is the "Comprehensive Wastewater Discharge Standard" .

[0040] The treatment steps of this embodiment are the same as the landfill leachate treatment steps of the first embodiment.

[0041] Case 4: It is proposed that a wool spinning factory will process 1500m per day 3 Dyeing and finishing wastewater as an example

[0042] The water quality comparison of each process before and after the treatment of dyeing and finishing wastewater in a wool spinning factory is shown in Table 5 below:

[0043]

[0044] Note: The discharge standard is the "Comprehensive Was...

Abstract

The invention discloses a technology for treating high-concentration and high-chromaticity wastewater. The technology realizes wastewater treatment by the following steps: treating by a two-stage anaerobic tank, a water distribution tank, a filter tank and a one-to-three-stage aerobic biological tank; disinfecting in a clear water tank; and recycling the water reaching the standard in the water distribution tank. The treatment technology is suitable for treating various types of high-concentration and high-chromaticity wastewater, such as garbage percolate, dye mother liquor, dyeing and finishing wastewater, cane mill alcohol waste mash, DDNP (diazodinitrophenol) waste liquor, soy sauce water, traditional Chinese medicine wastewater, electrophoretic paint wastewater and the like. According to the technology, various types of high-concentration and high-chromaticity wastewater can reach the nationally specified discharge standard after treatment. In addition, the complicated high-concentration and high-chromaticity wastewater treatment is simplified, thereby greatly lowering the cost for treating the type of wastewater.

Description

technical field [0001] The invention relates to a high-concentration and high-chroma wastewater treatment process. Background technique [0002] In today's world, water resources are becoming more and more scarce, and various domestic sewage, industrial wastewater, agricultural and animal husbandry sewage are seriously polluting our water sources and living environment. [0003] At present, the treatment of high-concentration and high-chroma wastewater has always troubled people technically. There is no good report of successful experience at home and abroad, and the methods used have not achieved good treatment results, and the investment and operating costs are relatively high. The operating cost of treating one ton of high-concentration and high-chroma wastewater ranges from tens of yuan to hundreds of yuan. Take the comparison of landfill leachate treatment in a landfill in Kunming as an example. The currently used process technology is: hydrolysis, aerobic biological m...
