Embodiment Construction

[0016] A kind of industrial wastewater treatment process, see figure 1 , the process includes the following steps:

[0017] 1) The industrial wastewater to be treated enters the grease trap for oil separation treatment;

[0018] 2) The waste water after oil separation enters the coagulation reaction tank, and the flow device of the coagulation tank is opened to carry out the coagulation reaction;

[0019] 3) The waste water after the coagulation reaction is filtered and sent to the storage pool for use;

[0020] 4) The waste water from the storage pool enters the micro-electrolysis reactor, and the pH value of the water in the micro-electrolysis reactor is adjusted with acid, which is controlled between 3 and 4; the acid can be one of hydrochloric acid, nitric acid or a mixture thereof; Activated carbon and iron powder are added into the reactor, and the amount of activated carbon and iron powder is both 0.01%-0.03% of the total amount of wastewater. Activated carbon and ir...

Abstract

The invention discloses an industrial waste water treating technology which comprises an oxidation reduction reaction, an anoxic hydrolysis reaction, an anaerobic reaction, an aerobic biological reaction, ultrafiltration, nanofiltration and adsorption. The technology provided in the invention is capable of synchronous and effective removal of carbon-containing organic pollutants and nutrient elements like nitrogen and phosphor, enables final chemical oxygen demend (COD) to reach less than 40 mg/L, ammonia nitrogen to be maintained below 6 mg/L and total phosphorus to be maintained below o.4 mg/L, and can be used for industrial production. According to the invention, the concentrate of ultrafiltration and nanofiltration is subjected to cyclic and repeated treatment and is thoroughly degraded, producing no waste liquid; therefore, good economic and environmental benefits are obtained.

Description

technical field [0001] The invention relates to a factory water treatment process, in particular to an industrial waste water treatment process. Background technique [0002] Chemical manufacturers need to insulate and heat the raw materials in many reactors, usually using steam to insulate and heat, and the industrial wastewater after cooling has the characteristics of large discharge and low pollution. At present, the waste water is mixed with rainwater after entering the pool, and most of it is discharged as discharge water, and a small amount is used as primary reuse water, which is only used for watering flowers and cleaning the ground. The boiler water needs to be added after being treated with tap water again, which increases the usage of tap water. Under the current situation of severe shortage of water resources and mobilization of energy conservation and emission reduction by the whole society, it is very unfavorable for the full utilization of resources and does ...
