1、 Overview

The continuous microwave sewage experimental treatment device is mainly used for experiments. Different sewage is tested by mixing different chemicals, adjusting microwave power density and controlling microwave irradiation time. The pollutants in the water are degraded and transformed through physical and chemical operations to achieve the purpose of purification. this Experimental equipment Small size, convenient transportation, and access to complex working conditions for on-site testing.

2、 Microwave chemical sewage treatment process

1. Compared with the traditional sewage treatment process, the microwave sewage treatment process has the advantages of greatly simplifying the process flow, reducing a large number of pipe network projects, and having no special requirements on the pH concentration and temperature of the incoming water.

2. Regulating tank: regulate water quantity and quality to reduce impact load on subsequent treatment structures;

3. Mixer: fully mix and shake the sewage with the 1 # and 2 # additives;

4. Microwave reactor: Physicochemical reaction between pollutants and additives and physicochemical reaction catalyzed by microwave at low temperature;

5. Sedimentation filtration equipment: realize solid-liquid separation to achieve the purpose of discharge or reuse, and sludge is dehydrated and transported outside or used for other purposes.

6. Under the joint action of additives and microwave, pollutants in water will undergo intense catalytic, physical and chemical reactions, transform into insoluble substances or gas will be separated from water. Macromolecules and refractory organic pollutants in water will be separated into small molecules under the joint action of microwave and additives, and will be combined with additives to generate fast settling flocs for removal; Metal ions can be directly combined with additives to form fast settling flocs; Ammonia nitrogen is converted into ammonia gas and escapes; Phosphorus in water is converted to insoluble phosphate for precipitation and removal.

3、 Technical characteristics of microwave chemical sewage treatment

1. The process flow is short, the flocculation sedimentation speed is fast, and the floor area is small. The project that uses microwave sewage treatment technology to treat 2500 tons of water per day covers a total area of less than 300m2, of which the microwave energy water treatment unit equipment only covers an area of 64m2, about 1/6-1/10 of the ordinary activated sludge process (the total area of traditional methods is more than 2000m2);

2. The project investment intensity is low and the construction period is short. Due to the uniqueness of the equipment itself, it is unnecessary to lay huge pipe networks and pools, and the civil engineering is simple; The equipment is compact in structure and assembled in blocks. The construction and installation are fast and convenient, greatly shortening the construction period, and the daily processing capacity is 2500m ³ The engineering installation of a single unit can be completed in about half a month. When the equipment is running, the power consumption per hour is only 40 kilowatt hours, which is equivalent to 0.4 kilowatt hours of electricity/ton of water. The calculated comprehensive operating cost is about 0.5~1.2 yuan/ton;

3. The commissioning cycle is short. Due to the short process flow, there is no complicated commissioning and online commissioning stage of multiple units. Generally, the commissioning process only takes a few days to enter into continuous operation;

4. Strong sterilization and algae killing ability. Microwave has a high frequency penetration effect on bacteria and algae, with extremely strong killing capacity. It can kill microorganisms in a short time, and has a strong sterilization and algae killing function. In the microwave field, cyanobacteria can converge into large particles, turn yellow, settle and separate from water in a very short time;

5. Strong adaptability and high processing efficiency. Microwave sewage treatment technology can be widely used in municipal sewage, industrial wastewater, community reclaimed water reuse and other industries for water treatment, and the effluent can be discharged or reused up to the standard; Due to the particularity of the process, the machine can be started and stopped at any time during the operation process, without affecting the effluent effect, and the commissioning is simple and fast;

6. Realize small, decentralized and equipment oriented projects. Directly plug the source of pollution and save the huge underground long-distance sewage pipe network in urban construction.

4、 Applicable scope of microwave chemical sewage treatment

1. Domestic sewage: domestic sewage treatment and reclaimed water reuse of municipal (living quarters), large hotels and resorts;

2. Industrial wastewater: such as hospital wastewater, printing and dyeing wastewater, electroplating wastewater, papermaking wastewater, power plant circulating water, petrochemical wastewater, wastewater from water washing plant, alcohol sugar making wastewater, starch plant wastewater, landfill landfill leachate, poultry breeding slaughterhouse wastewater, mineral processing refinery wastewater, etc;

3. Sewage purification of rivers and lakes.
