Embodiment Construction

[0016] The invention relates to a method for treating waste water and waste gas in a soil restoration process. In the treatment method, a fast stationary-phase bioreactor system is used, and the system includes an oil-water separator and a modular stationary-phase bioreactor. Wherein, the stationary phase in the stationary phase bioreactor is composed of biomass charcoal, including but not limited to activated carbon, plastic materials, wood blocks, agricultural biomass waste, zeolite, gravel and other particles.

[0017] The stationary-phase bioreactor adopts the conditions of aerobic or anaerobic or both used alternately to treat waste water and waste gas. According to the different components and concentrations of organic pollutants in the wastewater and the quality requirements of the treated wastewater, this process can choose to use different aerobic or anaerobic methods or alternately use the two methods to treat the wastewater to maximize the treatment effect. and effi...

Abstract

The invention relates to a method for treating soil remediation process wastewater and waste gas. The method uses a fast fixed-phase biological reactor system. The system comprises an oil-water separator and a modularized fixed-phase biological reactor. The method includes: treating contaminated soil remediation eluting wastewater / waste liquid, treating pollution remediation wastewater of deep soil and underground water and treating contaminated soil remediation waste gas. By the method, the treated waste gas can be directly discharged into atmosphere, the treated wastewater can be recycled in soil remediation, and secondary pollution to environments is avoided.

Description

【Technical field】 [0001] The invention relates to a method for treating waste water and waste gas, in particular to a method for treating waste water and waste gas in a soil restoration process, and belongs to the technical field of environmental protection. 【Background technique】 [0002] Chemical manufacturing, petroleum refining, metal processing, automobile manufacturing, textile printing and dyeing, pulping and papermaking, electroplating and other industries are commonly caused by inorganic pollutants (including heavy metals, acids, alkalis and other inorganic substances) and organic pollutants (including pesticides, polycyclic Soil pollution caused by refractory pollutants such as aromatic hydrocarbons and petroleum hydrocarbons). Agricultural land is mostly polluted by heavy metals (including cadmium, nickel, lead, arsenic, etc.) These pollutants will cause serious harm to the environment such as soil and groundwater, the surrounding workers, and the health of resid...
