Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with specific embodiments.

[0013] The quality index of wastewater discharged from a production plant of an optical company:

[0014]

[0015] Treatment process of the present invention is:

[0016] A brief description of the process flow:

[0017] (1) After the waste water in the workshop removes sundries and large pieces of garbage through the grilles of each discharge outlet, it is discharged into the grease trap through the waste water pipeline, where oil, etc. are removed, and the oil residue is incinerated. Good effect for subsequent processing. The effluent flows to the regulating tank by itself, where the volume and quality of the wastewater are adjusted by air stirring to make it uniform;

[0018] (2) The wastewater after the adjustment tank has been mixed is pumped quantitatively to the coagulation reaction tank, and at the same time, the air is started to stir for 3.0 minute...

Abstract

The invention discloses a glassware processing wastewater treatment technology. The technology comprises the following steps: 1, processing wastewater is discharged to an oil separation pool, and water discharged from the oil separation pool flows to an adjustment pool; 2, wastewater discharged from the adjustment pool is pumped to a coagulation reaction pool, calcium hydroxide is added to wastewater to adjust the pH value to 7.5-8.5, a coagulant PAC and a flocculating agent PAM are added to carry out a coagulation reaction, the obtained wastewater automatically flows to an inclined tube sedimentation pool through a water distribution tank in order to realize solid-liquid separation, and sludge in a bucket is discharged to a sludge pool; 3, water discharged from the sedimentation pool automatically flows to a sand filter for sand filtration, and water discharged from the sand filter flows to a clear water pool; and 4, sludge in the inclined tube sedimentation pool is pumped to a sludge concentration pool through a sludge pump and is concentrated, the obtained sludge concentrate is press-dried to form sludge cakes, the sludge cakes are artificially cleaned and bagged, and a filtrate flows to a wastewater adjustment pool. The technology has the advantages of simplicity, increase of the processing capability of the sedimentation pool by utilizing a laminar flow principle, shortening the sedimentation time by shortening particle settlement distances, and increase of the processing efficiency by increasing the sedimentation area of the sedimentation pool.

Description

technical field [0001] The invention belongs to the treatment of waste water in the field of glass processing industry, in particular to the treatment of glass parts grinding waste water and cleaning waste water, in particular to a glass product processing waste water treatment process. Background technique [0002] Glass products are widely used in construction, daily use, medical treatment, chemistry, home furnishing, electronics, instrumentation, nuclear engineering and other fields. [0003] my country's glass deep-processing industry has developed rapidly. According to statistics, there are currently more than 4,000 glass deep-processing enterprises in my country, and there are more than 200 types of deep-processing glass, whether it is traditional home appliance glass, architectural glass, automotive glass or new energy-saving glass, solar glass, flat panel display glass, etc. The market supply All grew faster. As of the end of 2009, the annual output of the main type...
