Problems solved by technology

The landscape effect of the water body can be quickly improved by adding chemical agents, but there are certain skills in the use of agents, otherwise it is easy to cause chemical residues, which can produce secondary pollution while improving the water environment, causing damage to the water environment

Embodiment 1

[0020] The total length of a certain river is 1200m, and the water area is 45,000m 2 , water storage capacity 50,000 m 3 . The water body has no fluidity most of the time, the water source is mainly rainwater and sewage, and domestic sewage flows in, and the main function of the water body is flood control. Due to the poor water quality of the river and the influx of domestic sewage, the accumulation of pollution in the water body is obvious, and the bottom of the river is full of silt. As a result, the river is prone to black, smelly and black mud every summer. The bottom mud restoration agent described in this patent is used to carry out emergency treatment of water bodies in summer. From the beginning of June to mid-October, the sediment restoration agent is added every 5 to 10 days on average. The mass ratio of zeolite powder, activated carbon, oxygen enhancer, flocculant and adhesive in the sediment restoration agent used is 20~ 40:7~10:10~20:5~10:1~3. The particle si...

Embodiment 2

[0022] The total length of a certain river is 2000m, and the water area is 60,000m 2 , with a water storage capacity of 40,000 m 3 , the water body has no fluidity most of the time, the water source is mainly rainwater and sewage, and domestic sewage flows in, and the main function of the water body is flood control. Due to the poor water quality of the water source of the river, the influx of domestic sewage, and the obvious accumulation of water pollution, the river is prone to black odor and black mud every summer. The bottom mud restoration agent described in this patent is used to carry out emergency treatment of water bodies in summer. From the beginning of June to mid-October, the sediment restoration agent is added every 7 to 10 days on average. The mass ratio of zeolite powder, activated carbon, oxygen enhancer, flocculant and adhesive in the sediment restoration agent used is 30~ 50:5~7:1~10:1~5:3~5, the particle size of the sediment restoration agent used is Dos...

Abstract

The invention discloses a method for treating black and stink river and lake water body in a city and especially relates to a proportion of a sediment repairing agent. The sediment repairing agent is a mixture of zeolite powder, active carbon, oxygenation agent, flocculating agent and adhesive in a mass ratio of 10-50:5-10:1-20:1-10:1-5. The sediment repairing agent of the invention can effectively alleviate or even eliminate a phenomenon of black and stink water body, prevent a phenomenon of black mud turning over in water body and increase transparency of the water body.

Description

technical field [0001] The invention belongs to the field of urban river and lake treatment, and in particular relates to a bottom mud restoration agent used for emergency treatment of black and odorous water bodies in urban rivers and lakes. Background technique [0002] At present, in many cities in our country, river pollution is widespread and increasingly serious. All kinds of sewage are directly discharged into the river, especially when the sewage containing a large amount of organic pollutants enters the river, it often leads to seasonal or year-round black and smelly water bodies, which has become the current urban river in our country. The water environment problem that needs to be solved urgently in the pollution problem. [0003] The black and odorous state is an extreme state of the water body. The reason for this is that the organic matter in the anaerobic state is corrupted due to the lack of oxygen in the water body. Due to the high nitrogen, sulfur, phosphor...
