Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiments.

[0022] A treatment method for urban runoff wastewater. The pollution degree of wastewater is judged first, and after it is confirmed that it needs to be purified, it is treated with anaerobic treatment, activated carbon treatment, and water purification agent treatment, until the content of wastewater pollutants meets national standards and is discharged into groundwater. The specific steps include:

[0023] Step 1: Collect runoff wastewater and send the wastewater into the mechanical grid

[0024] Step 2: Filter the wastewater to be treated and measure the content of various pollutants in the wastewater;

[0025] Step 3: If the pollution is mild, it can be reused for irrigation of the green belt:

[0026] Step 3: The wastewater in the mechanical grille flows into the adjustment tank for agitation and pre-aeration treatment

[0027] Step 4: Drain the oxygen in the water, and drain th...

Abstract

The invention provides an urban runoff wastewater treatment method which comprises the steps: firstly, judging the pollution degree of wastewater, respectively carrying out anaerobic treatment, activated carbon treatment and water purifying agent treatment after confirming that the wastewater needs to be purified until the pollutant content of the wastewater meets the national standard, discharging the wastewater into underground water, and intercepting wastes through a mechanical grid; carrying out pre-aeration treatment through an adjusting tank; decomposing organic matters through an anaerobic reaction tank, an anoxic reaction tank and an aerobic reaction tank; and filtering the wastewater into reusable water through a continuous membrane filtration system. According to the invention, rural wastewater can be treated into reusable water, so that cyclic utilization of water is realized.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically relates to a method for treating urban runoff wastewater. Background technique [0002] Runoff wastewater refers to the useless water discharged in the daily life of residents, and the rainwater pollution caused by air pollution during rainfall. In fact, only a small part of the wastewater is treated, and most of it is directly discharged into the river without treatment. , Has caused considerable pollution to river waterways and wasted a lot of water resources. The existing urban wastewater needs to be treated. However, the existing traditional processing methods can only treat wastewater into wastewater that meets discharge standards, but cannot treat wastewater into reusable water. In the production process of the factory, different types of waste water are generated, which causes great troubles in the treatment of waste water. For example, a factory that produces ac...
