Abstract

The invention relates to a method for treating black and odorous contaminated water of rivers by adopting a modularized treatment device. The method comprises the following steps: (1) providing the modularized treatment device; (2) placing the modularized treatment device obtained in the step (1) in a target water area; and controlling parameters as follows: the planting density range of aquatic plants is 15 plants/m<2> to 35 plants/m<2>, and the specific surface area of a filler is 250m<2>/kg to 380m<2>/kg; the loaded amount of a microbial agent is 0.1kg/m<2> to 0.9kg/m<2>; and the water coverage area of the modularized treatment device is 15% to 35% the area of the target water area; and (3) placing the treatment device in the target water area for 10 to 15 days so as to enable the microbial agent to be successfully attached to and colonized into the filler; and then, keeping the treatment device in the target water area for 90 to 120 days, so as to complete treatment on the target water area. According to the method, the microbial agent is used for removing organic contaminants, the aquatic plants are used for absorbing nutrients from the water, and thus, the efficiency of greatly removing water contaminants is achieved; and meanwhile, the device employed in the method has the characteristics that the structure is simple, the mounting is convenient, the cost is low, the size can be changed according to field conditions through re-assembling of the device, the maintenance and management are simple, and reuse is achieved.

Description

technical field [0001] The invention relates to the technical field of black and odorous water pollution restoration, in particular to a method for treating black and odorous river polluted water by using a modular treatment device. Background technique [0002] Water bodies such as lakes and rivers in the city are an important part of the human settlements. Due to the characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water bodies, they can easily become receivers of industrial wastewater, domestic sewage, rainwater, and garbage. As a result, a large amount of dissolved oxygen in the water body is consumed, causing a lack of oxygen and a black and odorous state, which causes a crisis in the entire water ecosystem. Black and smelly urban rivers have become a common pollution problem in many large and medium-sized cities in my country. Black and smelly rivers are a common phenomenon in urban river networks in my country,...
