A multi-level method for comprehensive utilization of hot spring wastewater and heat

Abstract

The present invention relates to a multi-level method for comprehensive utilization of hot spring wastewater and heat. The multi-level comprehensive system for hot spring wastewater and heat includes four parts: hot spring swimming pool, wastewater ecological treatment part, bathing part, and spirulina breeding part; The hot spring swimming pool is connected with the hot spring wastewater plate heat exchanger, and then connected with the swimming pool wastewater ecological treatment part; the swimming pool wastewater ecological treatment part is divided into two sections; the bathing part includes a bath room, a boiler room, and a bath wastewater plate heat exchanger; The spirulina cultivation part is composed of an algae pond, a stirrer, a temperature detector, a controller, and a plate radiator. The water quality of the hot spring swimming pool wastewater treated by the technical scheme is already safe when it enters the fish pond. At the same time, the present invention uses a plate heat exchanger to exchange the heat of the hot spring wastewater and bath wastewater for bathing and spirulina cultivation, without any contact with the hot spring wastewater. Direct contact with bathing wastewater greatly reduces the energy consumption of bathing and spirulina cultivation.

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.
