Abstract
The invention relates to a waste water treatment process, in particular to a glyphosate waste water treatment process. The glyphosate waste water enters a catalytic micro electrolytic cell, a neutralization aeration tank, a flocculation and sedimentation tank, a biological water distribution tank, a baffled anaerobic reactor, an intermediate water tank, a continuous aerobic tank, a settling tank, a coagulation sedimentation tank, a BAF water incoming tank, a BAF reaction tank, a regulating water tank and a chemical phosphorus removal tank. By means of the process, the COD of waste water is not larger than 100mg/L, ammonia </= 15mg/L, PH ranges from 6 to 9, and the first level of emission standard can be met.
Description
Technical field
The present invention relates to a kind of waste water treatment process, be specifically related to a kind of glyphosate waste water treatment process.
Background technology
Glyphosate is a kind of wide spectrum, high-efficiency low-toxicity, non-selective post-emergence herbicide, chemical name is N-phosphonomethyl-glycine, commodity are called agriculture and reach, and in agriculture production, current glyphosate has become the maximum pesticide species of China's export amount, are also the maximum pesticide species of global output and sales volume.Can produce a large amount of containing formaldehyde, dimethylphosphite, pmida98, glyphosate in glyphosate production process, and the waste water of salt, COD mass concentration is up to (5-8) × 104 (mg/L), total phosphorous, up to 5000-8000 (mg/L), becomes one of difficult organic waste water.At present, glyphosate waste water low-cost processes is still a difficult problem.
Summary of the invention
The object of the invention is to: the glyphosate waste water treatment process that a kind of efficient, low cost is provided.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of glyphosate waste water treatment process, described glyphosate waste water by pipeline enter successively catalysis and micro-electrolysis pond, in and aeration tank, flocculation sedimentation tank, biochemical distribution reservoir, anaerobic baffled reaction device, intermediate pool, continuously Aerobic Pond, settling bowl, coagulative precipitation tank, BAF pump sump, BAF reaction tank, balancing tank, chemical dephosphorization pond.
Described flocculation sedimentation tank becomes mud cake with the mud in coagulative precipitation tank by filter press, then transports outward away.
In described and aeration tank enters milk of lime, in and the bottom of aeration tank be furnished with air aeration system, carry out pneumatic blending.
PAM is added in described flocculation sedimentation tank.
Add PAC, PAM in described coagulative precipitation tank, remove the suspended substance in waste water and organism further, guarantee that waste water can qualified discharge.
Described chemical dephosphorization pond: in add lime, remove the phosphoric acid salt in waste water.
Adding indigo plant in described Aerobic Pond must high efficiency composition aerobic bacteria and carrier clearly, and carrier is 30-80 object gac.
Beneficial effect of the present invention is: by waste water treatment process of the present invention, makes the COD≤100mg/L in waste water, and ammonia nitrogen≤15mg/L, PH is 6-9, reaches first discharge standard.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.

Described flocculation sedimentation tank becomes mud cake with the mud in coagulative precipitation tank by filter press, then transports outward away.
In described and aeration tank enters milk of lime, in and the bottom of aeration tank be furnished with air aeration system, carry out pneumatic blending.
PAM(polyacrylamide is added) in described flocculation sedimentation tank.
Add PAC(polymerize aluminum chloride in described coagulative precipitation tank), PAM(polyacrylamide), remove further the suspended substance in waste water and organism, guarantee that waste water can qualified discharge.
Add lime in described chemical dephosphorization pond, remove the phosphoric acid salt in waste water.
Adding indigo plant in described Aerobic Pond must high efficiency composition aerobic bacteria and carrier clearly, and carrier is 30-80 object gac.
By waste water treatment process of the present invention, make the COD≤100mg/L in waste water, ammonia nitrogen≤15mg/L, PH is 6-9, reaches first discharge standard.
