Abstract
The invention discloses a sewage treatment method based on inorganic and organic heavy metal absorbents. The method comprises the following steps: first, introducing sewage into a pH regulating tank; then, introducing the regulated sewage into a reaction tower; adding air and catalysts into the reaction tower, wherein the catalysts are cast scrap iron and active carbon; then, introducing the sewage in the reaction tower into a sedimentation basin; adding an inorganic heavy metal absorbent; introducing the sewage into a pipeline mixer; adding an organic heavy metal absorbent; last, introducing the sewage in the pipeline mixer into a solid-liquid separator; depositing solid impurities containing heavy metals in the sewage at the bottom of the solid-liquid separator; discharging liquid in the sewage in the solid-liquid separator. According to the invention, all kinds of heavy metals are absorbed thoroughly through the well-designed inorganic heavy metal absorbent and the organic heavy metal absorbent; the effect is obvious.
Description
Technical field
The invention belongs to a kind for the treatment of process of industrial heavy metal wastewater thereby, be specially a kind of based on inorganic and sewage water treatment method organic heavy metal sorbent material.
Background technology
In much mechanical means processing, manufacturing concern; the enterprises such as such as plating, five metals, wiring board production; in the production waste that these enterprises discharge; much contain a large amount of heavy metals; heavy metal is often referred to the metal that proportion is greater than 4 or 5; approximately have 45 kinds, as copper, lead, zinc, iron, brill, nickel, vanadium, girl, load, admire, manganese, fluorine, mercury, tungsten, aluminium, gold and silver etc.; Although the heavy metals such as manganese, copper, zinc are the trace elements of the required use of vital movement, but institute such as most of heavy metal vital movement as non-in mercury, lead, good fortune etc. is necessary, and all heavy metals to exceed finite concentration all poisonous to human body, if to these, the sewage containing heavy metal is not processed, it is directly emitted in physical environment, and it will cause serious heavy metal environmental pollution.
Heavy metal contamination hazard rating depends on concentration and the chemical form that heavy metal exists in environment, food and organism, heavy metal is generally extensively present in occurring in nature with natural concentration, but because exploitation, smelting, processing and the business manufacturing activities mouth benefit of the mankind to heavy metal increases, cause many heavy metals to enter in atmosphere, water, soil as lead, mercury, good fortune, brill etc., cause serious environmental pollution, the heavy metal existing with various chemical states or chemical form, after entered environment or the ecosystem, will retain, accumulate and move, work the mischief.As the heavy metal of discharging with waste water, even if concentration is little, also can in algae and bed mud, accumulate, by the body surface of fish and shellfish, adsorbed, produce food chain concentrated, thus the public hazards of causing.
On the other hand, if the direct discharge of these sewage containing heavy metal can cause again very large waste, if these heavy metals can be reclaimed, after processing, re-use, not only can cut the waste, and also can produce considerable economic benefit.
For general enterprises, the treatment process of its heavy metal containing sewage adopting is relatively backward, and treated sewage is difficult to reach the emission standard of national regulation, if adopt advanced equipment, cost is too high, and general enterprises is difficult to bear.
