Problems solved by technology

However, the task of membrane separation treatment technology in drinking water plants is still very arduous. For example, in the removal of microorganisms, membrane separation treatment technology has an absolute advantage over traditional sand filtration, but the price ratio is much higher than the UV + sand filtration method of microorganisms.
China's current micro-polluted source water focuses on organic pollutants, and membrane separation treatment technology is not very effective for dissolved pollutants

Embodiment 1

[0084] take figure 1 The process shown and image 3 The shown device purifies slightly polluted water to meet the requirements of the Sanitary Standard for Drinking Water. The treatment of slightly polluted water and each unit is as follows:

[0085] Slightly polluted water enters the Fenton reaction process through the water inlet pump, and hydrogen peroxide (H), metal salts (F1) and catalyst (A1) are added to the Fenton reaction tank, and the Fenton reaction is carried out after mixing by the mixing device; Fenton reaction process There is a stirring device in the middle to stir, and after a period of reaction, it enters the coagulation and sedimentation process; in the coagulation and sedimentation tank, the small suspended matter, colloidal matter, and metal salts in the wastewater are precipitated by adding a coagulant (B1). The treated clear water can directly enter the disinfection and oxidation reaction process because the relevant indicators reach the "Drinking Water...

Embodiment 2

[0089] The process of Example 1 is adopted to purify slightly polluted water, so as to meet the requirements of the "Drinking Water Hygienic Standard", and the processing conditions of each unit are shown in Table 3.

[0090] table 3:

[0091]

Embodiment 3

[0093] Adopt embodiment 1 process to carry out micro-polluted water body purification, to reach " drinking water sanitation standard " requirement, each unit treatment situation is as table 4.

Abstract

The invention discloses a method for purifying water of a micro polluted water source, which comprises a Fenton reaction process (4), a coagulative precipitation process (5) and an oxidant oxidation and disinfection process (8). The Fenton reaction process (4) means to add oxidant, metal salt and catalyst into the water of the micro polluted water source to be treated with metering respectively so that the oxidant decomposes the organic substances in the sewage and the organic substances are removed from the sewage; the coagulative precipitation process (5) means to add a coagulant into the sewage after the oxidation treatment to precipitate small granular suspension substance, colloidal substance and metal salt in the wastewater; and the oxidant oxidation and disinfection process (8) means to perform further oxidant treatment on the clean water obtained in the previous process to remove residual hydrogen peroxide from the water and disinfect the clean water, wherein the disinfected clean water can be used as drinking water. The invention also provides a treatment device for purifying the water of the micro polluted water source.

Description

technical field [0001] The invention provides a method and a treatment device for purifying slightly polluted water source water quality. The clear water treated by the method or the treatment device can meet the Hygienic Standard for Drinking Water and can be used as drinking water. Background technique [0002] In recent years, with the development of my country's industry and the increase of agricultural chemicals, drinking water sources have been seriously polluted, and it is showing a trend of development. my country's seven major water systems and three major lakes have all been polluted to varying degrees. According to the detection of the environmental protection department, more than 90% of my country's urban waters have been seriously polluted, and about 50% of key urban water sources do not meet drinking water source standards. The national surface water More than 60% of the water quality has fallen below Class IV, and has completely lost its function as a source ...
