How to clean up the silt in the river? What are the benefits of river silt removal?

1 5 step by step reading.

1. Yard treatment and on-site treatment: The yard treatment method refers to the silt is dredged out and transported to the designated silt yard for treatment. The in-situ treatment method does not dredge out the sediment, but directly covers the sediment under water or drains the overlying water body and then dewaters, solidifies or physically rinses.

2.Resource utilization and conventional disposal: Sludge is essentially engineering waste, and according to the principles of reduction, harmlessness and resource utilization of solid waste treatment, resource utilization of sludge should be considered as much as possible.

3.Passivation treatment technology of polluted sludge: passivation treatment is based on the fact that the heavy metals in the sludge have different active states in different environments, and the corresponding chemical materials are added to convert the unstable heavy metals in the sludge into stable heavy metals and reduce the activity of heavy metals, so as to achieve the purpose of reducing pollution.

4.Yard sludge disposal technology: The silt yard is usually set up in the dredging project, and the yard treatment technology is to start from the initial blowing and filling stage, using a series of treatment measures to quickly promote sedimentation and rapid consolidation, and combined with surface treatment technology, the silt dump is used for turnover or to achieve the rapid recultivation of the silt dump.

5.Sludge resource utilization technology: Sludge resource utilization technology also includes heat treatment methods for making silt into bricks and tiles. The heat treatment method is to convert the sludge into building materials through heating and sintering, which can be divided into sintering and melting according to the difference in principles.

Jiuding filter press can be used.

Dispose. The treatment process is as follows: the sludge enters the sludge thickening pipe by the sewage pump, the supernatant enters the clear water pool, the precipitated sludge enters the sludge filter press with the slurry pump, and the mud cake can be directly transported out.

At present, the domestic filter press manufacturer Henan Jiuding filter press is a conscientious enterprise, moderate, quality assurance, technical team and after-sales team are more than 20 years of industry experience, equipment before leaving the factory to do practical tests for customers to buy assured and satisfactory products to invest a lot of resources and energy, you can go to learn about Henan Jiuding.

On-site treatment: The sediment is not dredged out, the sediment is directly covered or drained underwater, and the water body is dewatered, solidified or physically washed after being overlaid.

Resource utilization: Sludge is an engineering waste, and the sludge is heated and sintered in accordance with the principles of reduction, harmlessness and resource utilization of solid waste treatment, and the sludge is converted into building materials.

River dredging can deepen the river channel, which is conducive to drainage, flood discharge, and purify water quality, and the silt of the river channel is relatively fertile, which can be used as the cultivation soil for artificial vegetation along the coastHowever, the formation of silt at the bottom of the river is caused by over-reclamation and geological factors in the upstream area, and the dredging of the river channel may also damage the living environment of aquatic animals and plants at the bottom of the riverThe siltation of the river has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation, and the dredging and dredging project of the river has been carried out in order to restore the normal function of the river and promote the rapid and sustainable development of the economy and society

The river will be deepened and widened through governance, the river water will become clear, and the production conditions and living environment of the masses will be significantly improved, so as to achieve the goal of "clear water, smooth river, green bank and beautiful scenery".

The advantage of cleaning up the silt in the river is to reduce the breeding of bacteria, so that the river can be deepened and widened through treatment, the river water will become clearer, and the production conditions and living environment of the masses will be significantly improved"The water is clear, the river is smooth, the bank is green, and the scenery is beautiful"goals.

It can ensure that the flood control in the region is safer and promote the steady development of the agricultural economy. At this stage, the following problems exist in the dredging and dredging of rivers in China: the river channel is not well governed, the river channel is prone to swing, forming a certain dangerous section, a large amount of sediment siltation, and the riverbed is constantly raised, reducing the flood discharge capacity of the river.

Because some sandy soil embankment sections contain sand foundations, when the water level of the river channel is high or the water flow is too large, it is particularly prone to embankment failure accidents, and some embankment sections are constructed by means of embankment series ditch, which will have a great impact on the safety performance of the embankment. By doing a good job in river dredging and dredging, the amount of silt accumulation in the river can be effectively reduced, and the flood discharge capacity of the dam can be better improved. The construction personnel should also strengthen the management of the river channel to ensure that the river is more stable and fundamentally reduce the occurrence of river dangers.

What is the benefit of river silt removal? In line with the sludge cleaning, it can make the water source cleaner, and it doesn't matter if you open the stage below, I'm tired.

It can clean the water of the river.

Illegal. Illegal sand mining activities carried out in the name of dredging will be seriously investigated and dealt with by the water conservancy department. However, if the siltation of the river is really serious and affects the flow of floodwater, an application for dredging can be submitted according to the procedure, and the water conservancy department will carry out unified planning according to the actual situation and formulate a scientific dredging plan.

The mud discharged into the river not only pollutes the water quality, but also raises the riverbed and affects the river's flood capacity. Therefore, we filed a case and punished the illegal act of discharging mud into the river in accordance with the law, and ordered the unit to clean up the surrounding area within 15 days, and the party concerned expressed his willingness to cooperate.

Article 225 of the Criminal Law of the People's Republic of China: Where state provisions are violated by any of the following illegal business activities, disrupting market order, and the circumstances are serious, a sentence of up to five years imprisonment or short-term detention is to be given, and/or a fine of between 1 and 5 times the amount of unlawful gains; where the circumstances are especially serious, a sentence of five or more years imprisonment is to be given, and a concurrent fine of between 1 and 5 times the amount of unlawful gains or confiscation of property is to be given

1) Engaging in monopoly or monopoly goods or other restricted items as provided for by laws and administrative regulations without permission;

2) Buying and selling import and export licenses, import and export certificates of origin, and other business licenses or approval documents provided for by laws and administrative regulations;

3) Illegally operating **, **, or insurance business without the approval of the relevant competent state departments, or illegally engaging in fund payment and settlement business;

4) Other illegal business activities that seriously disrupt market order.

Legal analysis: Reservoir dredging needs to be written to the local people's water administrative department at or above the county level to write an application for dredging for approval.

Legal basis: Zhaotan "Water Law of the People's Republic of China" Article 25 Local people at all levels shall strengthen the leadership of irrigation, drainage, soil and water conservation, and promote the development of agricultural production; In areas prone to salinity and contamination, measures should be taken to control and lower groundwater levels.

1. Land landfill: The land landfill of silt is divided into separate landfill and mixed landfill with municipal solid waste;

2. Production of fertilizer: The fertilizer utilization of sludge has a history of many years at home and abroad, and has achieved certain results. Through the continuous improvement of technology, the fertilizer generated after composting has a high content of organic matter, which can improve the soil at the same time;

3. Energy stimulation and erection of chemical fiber land utilization: mainly including incineration, low-temperature oil production technology, biogas production and other methods;

4. Reclamation and land reclamation: Silt reclamation can solve the problem of insufficient land area of the port and meet the needs of port construction;

5. Production of building materials: The sludge contains a large amount of inorganic matter in Mingbi, which can be used as a raw material for building materials such as bricks, cement and ceramsite.
