Method for multi-level comprehensive utilization of hot spring waste water and heat

Abstract

The invention relates to a method for multi-level comprehensive utilization of hot spring waste water and heat. The method for multi-level comprehensive utilization of hot spring waste water and heatcomprises four parts: a hot spring swimming pool, a waste water ecological treatment part, a bathing part and a spirulina cultivation part, wherein the hot spring swimming pool is connected with a hotspring waste water plate heat exchanger and then connected with a swimming pool waste water ecological treatment part. The swimming pool waste water ecological treatment part is divided into two sections. The bathing part comprises a bathing room, a boiler room and a bathing waste water plate heat exchanger. The spirulina culture part consists of an algae pond, a stirrer, a temperature detector,a controller and a plate radiator. The water quality of hot spring swimming pool waste water treated by the method is safe when entering a fish pond; meanwhile, the heat of the hot spring waste waterand the bathing waste water is exchanged to be used for bathing and spirulina cultivation through the plate heat exchangers, and the energy consumption of bathing and spirulina cultivation is greatlyreduced due to no direct contact with the hot spring waste water and the bathing waste water.

Description

technical field [0001] The invention belongs to the technical field of hot spring water treatment and heat utilization, in particular to a method for multi-level comprehensive utilization of hot spring wastewater and heat. Background technique [0002] Our country is very rich in geothermal resources. Many regions have geothermal hot springs. When hot springs are discovered in the local area, hot spring resorts are generally built, which brings huge economic benefits. It is precisely because hot spring tourism can bring many benefits, but the waste water and heat of hot springs have not been effectively utilized and are wasted in vain. Some places use hot spring water, and just dig bigger pits to use the cooled hot spring water to raise fish, but not all hot spring water can be cooled to raise fish, because most of the hot spring water contains sulfate and other minerals. material elements, and the PH value is also high, which is not good for the growth of fish and aquatic ...

Problems solved by technology

At present, the commonly used solution is to place a heater in the water, but the problem is that the water temperature around the heater is too high, which is not conducive to the growth of algae, and it consumes a lot of energy.
