Problems solved by technology

[0003] However, as a new technology, constructed wetland still faces many challenges. Judging from the existing engineering practice, the long-term operation of constructed wetland still lacks security. If the design or management is improper, the system is prone to poor water flow or congestion, surface area water, clogging
Clogging causes the removal efficiency of constructed wetlands to drop, serious surface water accumulation, odor emission, and even leakage of pollutants
[0004] Usually constructed wetlands only export the fixed pollutants of the wetland system by harvesting plants. However, the pollutants purified by constructed wetlands cannot be completely removed by this method, and the solid derivatives derived from purification, such as microbial residues and extracellular polymers , Organic matter and chemical sediments that will not be degraded or decomposed in the future will be intercepted and filtered in the filter matrix, forming deposits in the matrix gaps, and gradually lead to physical blockage of the filter matrix and loss of wetland purification function
[0005] In addition, the distribution of sewage in the constructed wetland system is relatively simple, and the unreasonable ratio of components / nutrients in sewage will easily lead to poor purification effect of the system on some pollutants, and even lead to the leakage of accumulated pollutants, thus affecting Purification function of the system

Abstract

The invention provides a method for discharging silt in a muddy water environment. Silt is continuously pressed into an isolation space by pressure difference; then, the silt in the isolation space is subjected to solid-liquid separation; separated solid can be transferred for treatment; separated liquid is discharged into a set region. The invention also provides a silt discharging purification device, which comprises a silt collecting box, a silt guide device, a silt sucking device and a solid-liquid separator. The technical scheme has the advantages that the pollutant transfer efficiency of the muddy water environment can be improved; the phenomena of blockage and pollutant leakage are prevented; the sewage ingredients can be deployed; the sewage distribution is optimized, so that the purification function of a system is enhanced; the sewage purification requirement can be met; the biochemical reaction flow process in the muddy water environment can be optimized; the purification effect is improved.

Description

technical field [0001] The invention relates to the field of environmental water body purification, in particular to a method for discharging silt in a muddy water environment and a silt discharge and purification device. Background technique [0002] With the development of society and economy, people have higher and higher requirements on the environment, especially the water environment. The current water environment pollution is the most important environmental problem facing our country. Under the situation of severe water pollution, constructed wetlands, as a typical ecological treatment technology, have the characteristics of low investment and maintenance costs, good effluent quality, and low secondary pollution. So far, they have been widely used in various types of sewage treatment around the world. . Statistical analysis of 225 constructed wetland projects in my country: Since 2003, the growth trend of annual sewage treatment capacity of constructed wetlands is s...
