Problems solved by technology

In the process of river pollution control, the bottom mud cannot be treated, and often only the water body is treated. After the treatment is completed, the bottom mud releases pollutants into the water body again, so that the polluted river cannot be effectively treated.

Embodiment

[0049] Embodiment: a kind of river course pollution treatment system, see appendix figure 1 , including excavation module, separation module, cleaning module, mixing module, recovery module, aeration module, sequestration module, drying module, cleaning module, solidification module and reuse module.

[0050] The excavation module includes mud pumps and retaining dams, which are used to excavate the sediment in the river channel, and the excavated sediment is sent to the separation module; the separation module includes a filter screen for separating sand from water and mud. Under the filtering effect of the filter sieve, the sand and gravel are retained on the top of the filter sieve, and the mud and water are filtered out, and the filtered water and mud are sent to the mixing module, and the remaining sand and gravel are sent to the cleaning module; the cleaning module Including the cleaning tank and water, the sand and gravel sent to the cleaning module are repeatedly washe...

Embodiment 2

[0052] Embodiment two: a kind of river course pollution treatment method, comprises the following steps:

[0053] a. Silt excavation: Select a river section with a slow flow rate, use a dam to block the water flow, and then use a mud pump to pump out the sediment at the bottom of the river;

[0054] b. Separation: use a filter screen to filter the bottom mud, and separate the sand and stone in the bottom mud from water and mud;

[0055] c. Cleaning: Put the sand and gravel into the cleaning tank, and repeatedly use clean water to clean the sand and gravel in the cleaning tank;

[0056] d. Recycling: Recycle the cleaned sand and gravel as building materials;

[0057] e. Stirring: Mix the filtered water, mud and water generated during the cleaning of sand and gravel, and pass it into the mixing tank for full stirring;

[0058] f. Aeration: Pass the stirred mixture into the large aeration tank, add microorganisms that decompose organic matter into the mixture, and then us...

Abstract

The invention discloses a treatment system and method for river pollution and relates to the technical field of river pollution treatment. The problem is solved that in the prior art, river bottom sludge cannot be treated. According to the technical scheme, the system is characterized by comprising a digging module, an aeration module, a chelation module, a cleaning module, a solidification moduleand a recycling module; the method comprises the following steps of sludge digging, separation, cleaning, recycling, stirring, aeration, chelation, cleaning, drying, solidification and recycling. Thebottom sludge in a river is drawn out from the river and then treated, pollutants in the bottom sludge are removed, the situation can be avoided that secondary pollution of water is caused by the bottom sludge, and the bottom sludge after treatment can also be recycled.

Description

technical field [0001] The invention relates to the technical field of river pollution treatment, more specifically, it relates to a river pollution treatment system and treatment method. Background technique [0002] With the rapid development of the current society, a large amount of domestic sewage and industrial wastewater in some river basins are directly discharged without effective treatment, water and soil erosion, and direct discharge of untreated sludge from sewage treatment plants will affect the water quality in the river. Pollution, a large amount of pollutants are deposited in the bottom mud of the river. [0003] Most of the pollutants accumulate in the bottom mud of the river, and continuously release organic matter and nutrient salts into the water body. The existence of polluted bottom mud will also cause secondary pollution to the water body, making the water quality continue to deteriorate. Contains a large amount of polluting substances, which exist in ...
