Embodiment 1

[0064] This process is applied to the new project of a sewage treatment station of a bamboo product enterprise. The design volume of sewage treatment is 50t / d. The treatment process of the sewage station is as follows: pretreatment of waste water → collection pool → aeration and oxidation → micro-electrolysis → regulating pool → Adjusting pool→plate and frame filter press→intermediate pool→first-level multi-component electrolysis→reaction precipitation A→second-level multi-component electrolysis→reaction precipitation B→homogeneous tank→UASB→A2 / O→secondary sedimentation tank, the effluent must meet the discharge standard. The quality and discharge standards of sewage influent and effluent are shown in Table 1.

[0065] Control the pH in the sump to about 3.5; add the enhanced oxidant H to the aeration oxidation device 2 o 2 , the dosage is based on the mass concentration of hydrogen peroxide: COD=1:1, the molar concentration of Fe 2+ :H 2 o 2 =1:3 conversion; the filling r...

Embodiment 2

[0071] This process is applied to the new project of a sewage treatment station of a bamboo product enterprise. The design volume of sewage treatment is 40t / d. The treatment process of the sewage station is as follows: pretreatment of waste water → collection pool → aeration and oxidation → micro-electrolysis → regulating pool → Adjusting pool→plate and frame filter press→intermediate pool→first-level multi-element electrolysis→reaction sedimentation A→second-level multi-element electrolysis→reaction sedimentation B→homogeneous pool→UASB→air flotation tank→A2 / O→MBR pool, the effluent needs to reach nano Tube standard (partial reuse). The quality of sewage influent and effluent and the standards for receiving pipes are shown in Table 2.

[0072] Control the pH in the sump to about 3.5; add the enhanced oxidant H to the aeration oxidation device 2 o 2 , the dosage is based on the mass concentration of hydrogen peroxide: COD=1:1, the molar concentration of Fe 2+ :H 2 o 2 =1:...

Abstract

The invention discloses a diversified integrated processing process and device of high-concentration bamboo product wastewater. The diversified integrated processing device comprises a water collecting pond, an aeration and oxidization device, a microelectrolysis device, an adjusting pond, a press-filtering device, a middle water pond, a first-stage diversified electrolysis device, a reaction andprecipitation pond A, a second-stage diversified electrolysis device, a reaction and precipitation pond B, a homogenizing pond, a UASB, an A2 / O pond and a solid-liquid separating device. Various processing means are integrated for processing low-water-amount high-concentration bamboo product processing wastewater, all the processing means cooperate with one another, and the processing effect is improved.

Description

technical field [0001] The invention relates to the technical field of materials and environmental engineering, in particular to an integrated treatment process for multiplex treatment of high-concentration bamboo product wastewater. Background technique [0002] At present, the demand for the development and utilization of bamboo products in our country is increasing day and night. With the development of the times, the products are constantly updated, so the requirements for synthetic bamboo products are increasing day by day, and the complexity and difficulty of treatment of the waste water generated are also increased, which in turn causes Serious water pollution restricts the development of enterprises. The main components of bamboo are bamboo leaf flavonoids, polysaccharides, amino acid terpenes, phenolic acids, etc. A certain amount of bamboo coke industrial wastewater will be produced during the processing of bamboo products. The wastewater contains a large amount of...
