preparation example Construction

[0170] The preparation method of the in-situ growth MOFs of the magnetic carbon material comprises the following steps:

[0171] 1) Preparation of magnetic carbon materials:

[0172] 1.1) preparing the magnetic nanomaterials into an aqueous solution of magnetic nanomaterials, adding the carbonized material into the aqueous solution of magnetic nanomaterials and ultrasonically mixing to obtain a mixed solution 1;

[0173] 1.2) React the mixed solution prepared in step 1.1) in a constant temperature magnetic stirrer at 40°C-60°C and a rotation speed of 3rpm for not less than 24h to obtain mixed solution 2;

[0174] 1.3) After the mixed solution obtained after step 1.2) is cooled to room temperature, it is filtered through qualitative filter paper, and the filter cake is washed until the last filtrate is neutral to obtain a neutral adsorbent;

[0175] 1.4) Put the neutral adsorbent prepared in step 1.3) in a 40°C-60°C electric constant temperature drying oven to dry for not less...

Embodiment a

[0236] Take the following embodiment a as an example:

[0237] The domestic wastewater is subjected to tertiary treatment to obtain direct drinking water:

[0238] First, the domestic sewage to be treated enters the water inlet (1) (controllable valve at the nozzle) through the booster unit or tap water with its own pressure, passes through the rotor filter (3) to remove visible particles, and then passes through the coarse grid layer (4) , magnetic nano-adsorbent layer (5), fine grid layer (6), can obtain the flushing water that is used for garden, flowers and plants toilet etc., store with flushing water storage tank (32) then. After being treated by the primary treatment unit, oxygen is introduced, and the power supply (23) switch is turned on at the same time to provide a voltage of 1-5V to provide in-situ generation of hydrogen peroxide and hydroxyl radicals for secondary treatment of the flushing water; then use the clean water storage tank (33) STORAGE.

[0239] After...

Abstract

The invention provides an electro-adsorption-oxidation deep purification device for domestic wastewater / tap water. The electro-adsorption-oxidation deep purification device comprises a three-stage purification system (50), a three-stage purified water collection system (51) and a raffinate recovery system (52), wherein the three-stage purified water collection system (51) and the raffinate recovery system (52) are connected to the three-stage purification system (50). The three-stage purification system (50) comprises a three-stage purification system shell, a domestic wastewater or tap waterinlet (1), a first-stage treatment unit, a second-stage treatment unit, a third-stage treatment unit and a liquid separator (24), and the domestic wastewater or tap water inlet (1), the first-stage treatment unit, the second-stage treatment unit, the third-stage treatment unit and the liquid separator (24) are arranged in the three-stage purification system shell from top to bottom; the three-stage purified water collection system (51) comprises 3 liquid storage tanks arranged side by side, i.e., a rinsing water storage tank (32), a clean water storage tank (33) and a drinking water storage tank (34); and the raffinate recovery system (52) comprises a waste liquid storage tank (35) and a raffinate drain outlet (25). According to the device, the systems are simple in use, the treatment units of multiple stages can be comprehensively matched due to variation of water quality, disinfection byproducts in the domestic wastewater / tap water can be deeply purified, and the reutilization of thedomestic wastewater can be achieved.

Description

technical field [0001] The invention belongs to the field of waste water purification, in particular to a deep purification device for domestic sewage and tap water. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. For domestic sewage, it mainly comes from kitchen cooking, bathing, washing, toilet flushing water, etc. Domestic sewage basically does not contain heavy metals and toxic and harmful substances, and is mainly a complex mixture of various forms of inorganic and organic substances, including floating and suspended solid particles, colloidal and congealed dispersions and pure solu...
