Is Erhai Lake pollution related to homestays?

As the owner of the inn around Erhai Lake, the crime of "polluting Erhai Lake" seems to have been settled.

In fact, inns and homestays around Erhai Lake have already connected sewage pipes to the village sewage treatment system instead of directly discharging Erhai Lake; At the end of last year, nearly half of the inns installed biofilm sewage treatment systems; Moreover, as far as pollution sources are concerned, the hotel industry belongs to point source pollution, and its impact on Erhai Lake is already limited.

The renovation and protection measures of Erhai Lake in Dali City were originally based on non-point source renovation. At the same time, the management of inns and homestays was strengthened, and the behavior of directly discharging Erhai Lake was severely punished, and even the business was closed for rectification.

At present, the pollution interception project around Dali Lake is an example. The original design idea of the sewage interception project around the lake is to intercept the pollution sources that may directly flow into Erhai Lake on the ground, collect them uniformly, and purify them artificially and naturally through sewage treatment and pond purification.

At the same time, residents on the west side of Erhai Lake no longer use Cangshan water source (Cangshan Eighteen Rivers), but set up a natural water plant on the west side of Erhai Lake to extract Erhai Lake for water treatment and supply it to residents and inns.

The sewage interception project around the lake is a forward-looking project, and its sewage treatment capacity can meet the needs of the rapidly growing tourists and local residents in the future. However, the construction period of sewage interception project around the lake is relatively long, and the realistic problem facing Dali is that the existing sewage treatment facilities are far from meeting the needs of hotel industry growth.

The new situation requires Erhai Lake to improve the water quality rapidly, so shock therapy to suspend the business of hotels around Erhai Lake and reduce the number of tourists has become an option.
