With the development of society and the increase of urban population, the construction speed of sewage treatment facilities in China has greatly increased in recent years, and sludge production has also rapidly increased. Since sludge contains a large number of toxic and harmful substances (such as parasite eggs, pathogenic microorganisms, bacteria, heavy metals, etc.) and useful substances (such as plant nutrients, organic matter, water, etc.), it is necessary to treat and dispose of sludge in a timely manner so that Sludge reduction, stabilization, harmlessness and utilization. A water source heat pump and solar combined sludge drying system are provided. The sludge
Dryer is realized by the following method. The water source heat pump is the main heat source of the sludge drying system, and the solar heat source is auxiliary. The system makes full use of the sewage source heat pump to recover the secondary biological wastewater treatment plant as the main source of energy for drying the heat energy water sludge, utilizes the solar energy as a supplemental energy source, improves the efficiency, and at the same time overcomes the lean and intermittent process of solar energy itself that is odorless and wasteless. Continuous operation, zero emission clean production. The system includes: collector system, adiabatic dehumidification system, automatic control system and sludge dewatering system, among which the collector system includes: water source heat pump and solar collector, collector inlet device of fan and sewage system sludge dewatering system and sludge dewatering System connection, including: drying chamber, heating and dehumidification system, sludge feeding device, tipping device and receiving device, feeding device, feeding drying sludge dehydration chamber entrance, heating and dehumidification system, feeding device, feeding device device and regulator The heating capacity of the receiving device is relatively high, and the desiccant drying sludge drying process is sent to the storage silo from the discharge port.
