Embodiment Construction

[0039] Such as figure 1 As shown, the present invention provides TFT-LCD glass thinning wastewater treatment system, comprising:

[0040] a. Acid-base wastewater treatment department,

[0041] to combine figure 2 As shown, the acid-base wastewater treatment section includes a concentrated acid storage tank 11, a concentrated alkali storage tank 13, and an acid-base treatment pool 15. The inlet of the concentrated acid storage tank 11 is used as the inlet of the concentrated acid wastewater, and the inlet of the concentrated alkali storage tank 12 is used as the inlet of the concentrated alkali wastewater. , the outlet of concentrated acid storage tank 11 is connected to the inlet of acid-base treatment tank 15 through concentrated acid lifting pump 12, and the outlet of concentrated acid storage tank 13 is connected to the inlet of acid-base treatment tank 15 through concentrated acid lifting pump 14; There is a first mixer 16;

[0042] b. Mixed Wastewater Treatment Depart...

Abstract

The invention discloses a TFT-LCD glass thinning wastewater treatment system. The TFT-LCD glass thinning wastewater treatment system comprises the following parts of a, an acid and alkali wastewater treatment part, b, a mixed wastewater treatment part, c, an exhaust gas washing part, d, a lime slurry preparation part, e, an agentia preparation and storage part, f, an aeration part and g, a waste residue treatment part. Five kinds of wastewater (concentrated acid wastewater, concentrated alkali wastewater, fluoride-containing wastewater, phosphorus-containing wastewater and polishing wastewater) in a TFT-LCD glass thinning production process respectively enters respective corresponding treatment departments for classification; in addition, various treatment parts synergize with one anotherto form an organic unity, so that the wastewater in the production process can meet the function of full recovery and utilization. The treated wastewater can meet the water quality standards of plantproduction reuse and realizes closed-circulation, so that a large amount of water is saved and further the goal of responding to energy conservation and environmental protection of the nation is realised.

Description

technical field [0001] The invention relates to the technical field of glass thinning wastewater treatment, in particular to a TFT-LCD glass thinning wastewater treatment system. Background technique [0002] After TFT-LCD glass is thinned, it is mainly used in electronic industries such as mobile phone capacitive screens and liquid crystals, and has a huge market prospect. In the production process of enterprises, a certain amount of industrial wastewater will be produced. Wastewater mainly comes from alkaline wastewater produced by pre-etching treatment and cleaning, fluorine-containing wastewater produced by etching and post-etching cleaning, grinding wastewater, phosphorus-containing wastewater, acidic wastewater, etc.; cooling circulation system drainage, concentrated wastewater produced by pure water system, and waste gas treatment Device wastewater, etc. Wastewater contains a large amount of acid, alkali, phosphate, fluoride, suspended matter and a small amount of o...
