The details of the product

Product introduction

Solar desalination plant is a system that uses solar energy to convert seawater into fresh water. Solar collectors convert sunlight into heat energy, heat seawater, and desalinate it using the principles of evaporation and condensation.

Solar desalination plant is an environmental protection equipment that integrates solar photovoltaic power generation technology, efficient drinking water, and domestic sewage treatment technology, and is equipped with leisure or office area and bathing related functions. It aims to use renewable energy to synergistically treat drinking water and sewage. While achieving efficient resource utilization and sustainable environmental development, work, leisure, and life needs are also solved in one stop.

Composition of solar desalination plant

Intelligent distributed solar drinking water purification system equipment is a comprehensive water supply treatment system equipment with well water, river water, and natural lakes as water sources. It is mainly composed of the following key modules:

Solar photovoltaic panel power generation module: This is the energy supply core in the system. It directly converts solar energy into electrical energy through the photovoltaic effect to provide power for the entire sewage treatment system. The area and number of photovoltaic panels depend on the energy consumption requirements of the treatment system. The solar photovoltaic panel power generation module has a folding function.
Battery group energy storage power supply module: used to store the electricity generated by the solar photovoltaic panel when there is sufficient light, ensuring that the system can continue to operate stably at night or on cloudy days when there is insufficient light. The power supply battery adopts stacked batteries, such as stacked lithium batteries, stacked colloidal batteries, stacked lead-acid batteries, etc.
Diesel power generation system module: equipped with high-performance, unattended intelligent generators to meet the power demand on rainy days or when there is insufficient light, so as to ensure the stable and reliable operation of the system device.
Ceramic membrane pretreatment system module: This module system adopts inorganic ceramic membranes of domestic and foreign first-line brands, with a filtration accuracy of 0.1μm, which can effectively remove suspended matter and colloidal substances. This module mainly includes: reaction water tank, water production tank, water production pump, backwash pump and offline cleaning system, process pipelines and pipe fittings valves, fully automatic operation management control module, etc.
Reverse osmosis deep purification system module: The product configuration adopts advanced reverse osmosis RO membranes of domestic and foreign first-line brands, and the purification system adopts multi-stage filtration and disinfection to meet the water use standards of drinking water to meet daily drinking water needs. Mainly include: raw water pump, security filter, high-pressure pump, membrane assembly and bracket, offline cleaning system, process pipeline and pipe fittings, valve, fully automatic operation management control module, etc.;
Control system module: usually includes microcomputer control system and remote communication system, which is used to automatically monitor and manage the entire sewage treatment process, including aeration time, backflow ratio, equipment operation status, etc., to achieve efficient and energy-saving automatic operation. The remote communication system allows remote monitoring and fault diagnosis, which is convenient for real-time management and maintenance.

Technical principle

Technical principle of drinking water purification plant

Drinking water purification plant mainly treats sewage through the following steps:

1. Collection and pretreatment: First, collect domestic sewage, and remove large suspended solids and impurities through simple pretreatment such as grid and sedimentation.

2. Power supply system module: The built-in solar photovoltaic panels in the system convert solar energy into electrical energy, which is stored in the battery for use in the entire sewage treatment system, including energy-consuming links such as stirring, aeration, and pumping. On rainy days, the diesel generator supplies power to the power equipment and charges the battery.

3. Ceramic membrane pretreatment system module: This module system uses a first-line brand inorganic ceramic membrane with a filtration accuracy of 0.1μm, which can effectively remove suspended solids and colloidal substances. This module mainly includes: reaction water tank, water production tank, water production pump, backwash pump and offline cleaning system, process pipelines and pipe fittings valves, fully automatic operation management control module, etc.

4. Reverse osmosis deep purification system module: The product configuration is advanced and uses a first-line brand reverse osmosis RO membrane. The purification system uses multi-stage filtration and disinfection to meet the water use standards for drinking water to meet daily drinking water needs. Mainly includes: raw water pump, security filter, high-pressure pump, membrane assembly and bracket, offline cleaning system, process pipeline and pipe fittings, valve, automatic operation management control module, etc.

Technical principles of domestic sewage treatment plants

The domestic sewage treatment plant mainly treats sewage through the following steps:

1. Collection and pretreatment: First, collect domestic sewage, and then remove large suspended solids and impurities through simple pretreatment such as screens and sedimentation.

2. Solar power supply: The built-in solar photovoltaic panels in the system convert solar energy into electricity, which is stored in batteries for use in the entire sewage treatment system, including energy-consuming links such as stirring, aeration, and pumping.

3. Biochemical treatment: The core treatment part usually adopts biological treatment technology, such as activated sludge method, biofilm method (such as MBR membrane bioreactor) or anaerobic-aerobic (A/O) process, using microorganisms to decompose organic matter in sewage and remove nutrients such as nitrogen and phosphorus.

4. Deep purification: The water after biochemical treatment is further treated by deep treatment technologies such as sand filtration, activated carbon filtration or membrane filtration to further remove fine suspended solids and some soluble organic matter, and improve the effluent quality.

5. Disinfection: Finally, ultraviolet disinfection, ozone or chemical disinfectants are used to kill pathogens in the water to ensure the safety of effluent.

6. Reuse or discharge: The treated water can be used directly for non-potable purposes such as flushing and irrigation, or discharged into natural water bodies in compliance with local environmental discharge standards.

System leakage:

•Cause: Loose or damaged pipe connections or aging seals.

•Handling: Check and tighten or replace pipe connections, repair damaged parts, and replace aging seals.

Winter operation problems:

•Handling: Take antifreeze measures, such as insulation wrapping and adding antifreeze to ensure that the temperature of key components is appropriate.

Drinking water outlet deteriorates

•Cause: MCR and RO membrane systems are blocked.
