Description

Water body suspended matter catching method for water pollution treatment

Technical Field

The invention relates to the field of water pollution treatment, in particular to a method for catching suspended matters in a water body for water pollution treatment.

Background

With the increase of population and the rapid development of social economy, the urbanization process is accelerated, and the water environment pollution problem in China is more and more serious. The per capita water resource in China only reaches 1/4 of the per capita water resource in the world, about half of cities in China lack water, however, the water quality deterioration causes the problem of water resource shortage and frosts. Rivers and lakes in China are generally polluted, most lakes are eutrophicated to different degrees, and main water systems are obviously polluted. In seven water systems (a Zhujiang river system, a Changjiang river system, a yellow river system, a Huai river system, a Liaohe river system, a sea river system and a Songhua river system) in China, the types of related pollutants are as many as 2000, and the number of the types of the pollutants in water is kept in a state of increasing continuously. Wherein, the water environment quality of Huaihe river, yellow river and sea river is the worst, and 70% river reach is polluted. The serious siltation at the river mouth is caused by the flow cutoff phenomenon at the middle and lower reaches of yellow river, Huaihe river, sea river and the like; many small and medium rivers become sewage rivers due to excessive sewage discharge of the town industry and cannot be utilized by human beings.

The water body pollution is mainly from industrial wastewater, agricultural wastewater, domestic sewage and the like. With the rapid development of social economy, the waste water and the discharge amount thereof are continuously increased, according to statistics, the increase speed of the waste water and the discharge amount thereof is 18 hundred million m3 every year, the random discharge of the urban domestic sewage and the industrial waste water pollutes rivers and underground water sources around cities, the content level of organic pollutants such as trihalomethane, chloroacetic acid, heavy metals and the like is high, the risk of distortion and mutation of water quality is increased, and the health of people is seriously influenced. The rural water still has a deep well water taking mode, and the water taking mode has poor water source fluidity, is easier to cause heavy metal enrichment, and harms the nervous, urinary, reproductive and other systems of the human body. Therefore, the method is intuitively important for treating water pollution of the water body;

polluted water contains a large amount of suspended substances, which refer to solid substances suspended in water, including inorganic substances, organic substances, silt, clay, microorganisms and the like which are insoluble in water. The content of suspended matters in water is one of indexes for measuring the water pollution degree; suspended matters are the main reason for causing water turbidity, and organic suspended matters in the water body are easy to ferment anaerobically after being deposited, so that the water quality is deteriorated;

however, the existing water body suspended matter catching method for water pollution treatment is single, and is difficult to directionally remove emulsion oil drop-shaped substances in wastewater, so that the emulsion oil drop-shaped substances are difficult to reasonably treat when being discharged, and a discharged water source enters an external environment, so that the water body is rich in oxidation.
