Background technology
The source of high-concentration ammonia nitrogenous wastewater is many, discharge capacity is big, unprocessed or can cause the generation of body eutrophication, induction carcinogen after processing the discharge of incomplete ammonia nitrogen waste water, and environmental and human health impacts is threatened. At present, the process of high-concentration ammonia nitrogenous wastewater is just being increasingly subject to the concern of people. Soil filtration, as a kind of ecological soil treatment method, can not only be effectively reduced the pollutant levels in ammonia nitrogen waste water, makes the even reuse of water outlet qualified discharge, can utilize simultaneously in sewage, etc. nutrient substance supply plant growing, it is achieved the resource of sewage. Soil filtration method also makes soil aquifer process, and originates from traditional sewage irrigation technology. Under manual control by designing requirement by the sewage dosing of certain hydraulic load or pollutional load to the aerobic-anaerobic integration engineering structure being filled with composite soil filler, sewage is lentamente through having a special soil of good diffusion performance and to perimetric penetration and diffusion, pollutant are then removed by the Wuli-Shili-Renli system approach of the animal in soil, plant, microbial action and soil self.
In Efficiency for Soil Aquifer Treatment, the purification of pollutant is a complicated combined process, totally can be divided into biomechanism and abiotic mechanism. It is typically in the domestication stage at system initial stage based on abiotic mechanism, including filtering, retain, adsorb, chemical precipitation etc. Along with system is ripe gradually, soil grows substantial amounts of antibacterial, fungus, mycete, yeast, protozoacide, metazoa even maggot etc., defines longer biological chain. It is decomposed under microbial action by detention and the pollutant being adsorbed in soil or converts, becoming the main path removing pollutant, and protozoacide in soil and metazoa etc. are with microorganism for food. Additionally, plant soil filtration process in also function to important function, plant can utilize Root Absorption, etc. element as nutrient, most plants can also absorb heavy metal and some organic pollutants.
