Problems solved by technology

At present, the combined use of several of these methods can effectively remove organic matter, but this undoubtedly increases the treatment cost. The biological oxidation method has high efficiency in removing ammonia and can simultaneously remove multiple pollutants. It is low in cost and is widely welcomed. Development trend of removal of organic matter in treatment
On the basis of the conventional process, a biological filter is added to strengthen the removal of organic matter by using microbial degradation, but it is difficult to realize in the water plant renovation due to the large area; biological pretreatment can effectively remove ammonia nitrogen in water, but it needs to be used in the conventional treatment process Adding pretreatment structures at the front end increases the floor area and increases the one-time construction investment, which is not conducive to popularization and application

Abstract

The invention discloses reactor for removing organic matters from drinking water. The reactor comprises a water storage tank, and a sand filtering tank. In the sand filter tank, a material filtering layer, a bearing layer, a water distribution area, and a water discharge area are orderly arranged from top to bottom. The reactor also comprises an ozone contacting system, which is arranged between the water storage tank and the sand filter tank, a bioactive carbon processing area arranged in the sand filtering tank, and a backwashing system, which is connected to the bioactive carbon processing area. The reactor provides an environment, which is beneficial for the growth of biomembrane, and the biological degradation effect of microbes can be fully exerted, so the organic matters in drinking water can be eliminated. Moreover, the reactor is provided with a simple structure, thus the reactor can be easily applied to construction of new water plant, the effect is prominent, and the operation management is convenient.

Description

technical field [0001] The invention belongs to the field of drinking water purification, in particular to a reactor for removing organic matter in drinking water by using ozone oxidation and biofilm, and a method for removing organic matter in drinking water by using the reactor. Background technique [0002] With the development of the economy, the pollution of drinking water sources in my country is increasing day by day. It is mainly affected by the random discharge of urban industrial wastewater, rural domestic sewage, domestic garbage, livestock and poultry breeding waste, and non-point source pollution of pesticides and fertilizers. The discharge of pollutants is increasing year by year. There are many problems of persistent or seasonal organic matter exceeding the standard in different degrees, and there is a tendency to intensify, which seriously threatens the safety of drinking water and life and health of the people, and is a major social problem to be solved in our...
