At present, we are accelerating the construction of a resource-saving and environment-friendly society, promoting the development of the national economy under the guidance of the scientific outlook on development, and a pattern of energy conservation and emission reduction led by the government, dominated by enterprises and jointly promoted by the whole society is taking shape. The promotion of energy conservation and emission reduction has become the focus of promoting the healthy development of circular economy.

With the popularization of sewage treatment facilities and the improvement of treatment rate in China, the amount of sludge will reach 30 million tons / day. Due to the complex composition of sludge, if untreated sludge is not properly disposed, stacking and discharging untreated sludge everywhere will pose a great threat to the human environment. The cost of sludge treatment and disposal mainly includes on-site transmission cost, off-site transportation cost and landfill cost, and the most important factor affecting the cost is the amount of sludge.

The implementation of the project will make effective use of sludge, realize its resource utilization while achieving harmless treatment of sludge, and have considerable economic benefits and good social driving benefits.

The greenhouse system consists of the main body of the greenhouse, ventilation system, heating circulation system, internal and external weather stations and computer control system. The main frame of the main sunlight plate greenhouse is hot-dip galvanized steel pipe and steel plate, the top of the greenhouse is special aluminum profile, and the fan is used in the north and south of the ventilation system. It can be automatically turned on according to indoor and outdoor temperature, humidity and sunlight illumination parameters. The temperature sensor of internal and external weather stations adopts Japanese tokyo-100, with a resolution of 0.1 ℃. The humidity sensor adopts humier-15 tubular structure of American humier company, which is not affected by water condensation. At the same time, it adopts solid polymer patented technology, which has self-protection against greenhouse H2S, NH3 and other gas pollution, with a resolution of 0.5%. The wind speed and direction sensor adopts Davis 7911 of American company and adopts special engineering plastics, which has excellent anti ultraviolet aging effect. The light sensor adopts American Davis full spectrum light sensor, with the spectral range of 200-1100nm The computer system adopts the chipset with industrial single chip microcomputer of Intel company as the core. Reliable performance. Realize remote control through communication.

6. Dry material collection equipment

The dried sludge can be recycled: first, the mixture of sludge (about 50%) and shale or coal gangue is used to burn environmental protection bricks, which have the characteristics of thermal insulation, heat insulation, light weight and convenient transportation; Second, it can be used as fuel. When each kilogram of dry sludge is burned, it will produce 2000-3000 calories of heat, and 2.5kg of dry sludge is equivalent to the heat generated by 1kg of standard coal. Third, it can be used as a source of organic fertilizer. Municipal sludge is rich in organic matter, with the content of 55% and the content of nitrogen, phosphorus and potassium reaching 10%, all of which meet the national requirements for the efficiency of organic fertilizer.

The biggest features are: high efficiency, energy saving, environmental protection, safety, economy and reliability.
