Embodiment 1

[0037] 1) Set the start-up temperature of the heat exchange system at 40°C, and the average dosage of coagulant in the settling tank is: PAM: 5mg / l; PAC: 125mg / l. The chemical reagents in the adjustment tank are sodium hypochlorite and sodium hydroxide in turn; the initial concentrations of the chemical reagents are 7% and 10% in turn. The main pollutant discharge standards of the treated water body are: COD: ≤20mg / l; ammonia nitrogen: ≤1.0mg / l; SS: ≤3mg / l; BOD: ≤4mg / l; chroma: ≤8; total phosphorus: ≤ 0.2mg / l; PH: 6.5~8.5; water temperature: ≤35℃.

[0038] 2) After the waste water from the fermentation tank produced in the production process of the fermented Cordyceps powder is separated by the cyclone separator, the deslagging waste water enters the waste water monitoring buffer room equipped with temperature and waste water concentration monitoring sensors. According to the monitoring data of the monitoring sensors, the solenoid valve is automatically controlled And the wat...

Abstract

The invention discloses a method for purifying and deodorizing wastewater generated in a fermented cordyceps taishanensis powder production process. The method comprises the following steps: after separating the wastewater through a hydrocyclone (2), deslagging the wastewater and entering a wastewater monitoring buffer room (14), selectively passing through a first-level heat exchange system (3),a ceramic membrane ultrafiltration-nanofiltration combined operation system (6), a high-temperature anaerobic fermentation cylinder (7), a second-level heat exchange system (8), a settling tank (9), an air floating tank (10), an adjusting tank (11), and an intermediate-temperature UASB reactor (12), pumping into a recycled water collecting tank (13), and pumping generated sludge into a sludge tank(15), after dehydrating by a plate-and-frame filter press (16), sending to a unit with qualification for processing, and pumping filtrate into the settling tank (9).

Description

Technical field: [0001] The invention belongs to the field of industrial waste gas treatment, and in particular relates to a method for purifying and deodorizing waste water produced in the production process of fermented Cordyceps powder. technical background: [0002] Chinese cordyceps, Ophiocordyceps sinensis (Berk.) G.H.Sung et al. is the dry body of the sclerotia and stroma formed by Cordyceps fungus parasitizing on the larvae of bat moths. Cordyceps polysaccharide is one of the main active ingredients of Cordyceps sinensis. As a new type of biological immunomodulator, it is a physiologically active substance with extremely important medical value. Cordyceps polysaccharide can improve human immune function, increase white blood cells, and has been used clinically to treat malignant tumors. The fermented Cordyceps powder produced by our company is produced by fermentation of the strains isolated from natural Cordyceps by the Institute of Materia Medica, Chinese Academy...
