Embodiment Construction

[0041] The method for treating turmeric saponin wastewater is divided into three steps, that is, an acidic black liquor treatment step, a production wastewater treatment step and a soaking and cleaning water treatment step. The acidic black liquor treatment step accepts acidic black liquor; the production wastewater treatment step includes diaphragm press filtrate and rinsing wastewater; the soaking and cleaning water treatment step treats soaking and cleaning wastewater, equipment cleaning water and domestic water.

[0042] Detailed process method:

[0043] (1) Acidic black liquor treatment steps

[0044] 1) Adjustment pool

[0045] The quantity and quality of wastewater entering the wastewater treatment system may change at any time, which is very unfavorable to the normal operation of wastewater treatment structures. The greater the fluctuation of water quantity and water quality, the more unstable the treatment effect, and even cause serious damage to the wastewater trea...

Abstract

The invention relates to a method for treating wastewater from a diosgenin process. The method comprises the following steps of: treating acidic black liquor, treating production wastewater and treating soak cleaning water. According to the method, the wastewater from the diosgenin process is treated by categories, the treatment of each category of wastewater has strong pertinence, cyclic treatment can be realized, and the treatment cost is greatly lowered. The method has the advantages of relieving the toxicity to subsequent treatment units through strict and reasonable neutralization, sedimentation and other pretreatments, reducing the load of the subsequent treatment units by using the independent anaerobic treatment manner and not only reducing the production amount of sludge but also lowering the operating cost by combining lime and NaOH during pH adjustment.

Description

technical field [0001] The invention relates to a wastewater treatment method, in particular to a turmeric saponin process wastewater treatment method. Background technique [0002] The Han River, the source of water for the middle route of the South-to-North Water Diversion Project, originates in Shizhonggou, Ningqiang County, Shaanxi Province. The basin above Danjiangkou is 918 kilometers long, spanning cities such as Hanzhong, Shangluo, Ankang in Shaanxi and Shiyan in Hubei, with a catchment area of ​​100,000 square kilometers. According to the plan, the Danjiangkou Water Conservancy Project will control 60% of the area of ​​the Han River basin and 76% of the water volume after the impoundment operation. At present, due to the pollution problem of saponin processing, the Han River Basin is facing serious threats. The successful implementation of this project will establish standards for pollution control in this industry and completely solve the serious pollution situati...
