Embodiment 1

[0008] Embodiment 1: the comparative experiment of specific plant

[0009] Hongfengxing Chemical (Shenzhen) Co., Ltd. mainly uses the emulsion polymerization process to engage in the production of various water-based adhesives. During the production process, a small amount of high-concentration organic wastewater will be produced, and the main pollution index COD=5000~15000mg·L -1 , and BOD / COD-1 , and then add an appropriate amount of sodium chloride and sodium sulfate, so that the salt content in the waste water is 2% to 3%, and it is used as the influent of the plant composite bed.

[0010] Using 10 identical cylindrical containers (bottom area is 0.2m 2 ), put in gravel packing with a height of 60cm, and spread a layer of river sand under the packing for uniform water distribution. A water inlet pipe with a diameter of 2cm is set at a distance of 5cm above the filler. The water inlet pipe is connected to the nozzle, and there are holes with a diameter of 2.00mm on it. The...

Embodiment 2

[0017] Embodiment 2: application example of plant composite bed

[0018] Hubei Province Jingmen City Gurun Technology Co., Ltd. mainly produces ultraviolet photoinitiators, and the main pollution index of production wastewater COD=10000~20000mg·L -1 , the salt content is 2%~3%. After pretreatment, the main pollution index of wastewater COD=200~400mg·L -1 , and the salt content is 0.4% to 0.8%, which is used as the influent of the plant composite bed.

Abstract

The invention discloses a method for deep treatment of high-salinity industrial organic wastewater with a plant composite bed. The method is characterized in that the plant composite bed technology is mainly utilized, the method of mixed interplanting of salicornia europaea with one or more of cyperus alternifolius L., phalaenopsis, chlorophytum comosum, cyperus papyrus, acrous calamus, vetiver, murraya paniculata and Chinese fan palm is applied to the wastewater treatment field, the remarkable salt absorbing capability and collecting feature of salicornia europaea are used for absorbing salt in soil, improving the soil structure, increasing the soil fertility and preventing soil salinization, and the plant composite bed can continuously and stably treat high-salinity industrial organic wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for advanced treatment of high-salt industrial organic sewage by using a plant composite bed. Background technique [0002] The invention patent applied by Hongfengxing Chemical (Shenzhen) Co., Ltd., application number: 201310269731.1, reports a method for advanced treatment of industrial organic sewage by using a plant compound bed. The company mainly uses the emulsion polymerization process to engage in the production of various water-based adhesives. During the production process, a small amount of high-concentration organic wastewater will be produced, and the main pollution index COD=5000~15000mg·L -1 , and BOD / COD<30%, the biodegradability is poor, and it is difficult to deal with by general methods. After the pre-treatment, the plant composite bed technology is used for advanced treatment, which has achieved very good results and the system has remain...
